:::: Note (5): Predisposing factors: soft tissue (IDU, diabetes, surgery, trauma, varicella, vein donor, lymphedema); pneumonia (influenza), contacts w/ gas (pharyngitis and fasciitis).
:::: Note (6): Mastoiditis has become a rare entity, presumably as result of the aggressive treatment of acute otitis media.

::* 1.1 '''Pulmonary'''
:::* 1.1.1 '''Acute pulmonary histoplasmosis'''
::::* 1.1.1.1 '''Moderate severe or severe'''
:::::* Preferred regimen (1): Lipid formulation of [[Amphotericin B]] (3.0–5.0 mg/kg IV q12h for 1–2 weeks) {{then}} [[Itraconazole]] (200 mg tid for 3 days {{then}} 200 mg bid for a total of 12 weeks).
:::::* Preferred regimen (2): [[Methylprednisolone]] (0.5–1.0 mg/kg IV q24h) during the first 1–2 weeks of antifungal therapy is recommended for patients who develop respiratory complications, including hypoxemia or significant respiratory distress
:::::* Alternative regimen: The deoxycholate formulation of [[Amphotericin B]] (0.7–1.0 mg/kg q24h IV) is an alternative to a lipid formulation in patients who are at a low risk for nephrotoxicity.
:::::* Note (1): In severe cases, cases accompanied by respiratory insufficiency, or hypoxemia, anecdotal reports suggest that corticosteroid therapy may hasten recovery
:::::* Note (2): The pulmonary infiltrates should be resolved on the chest radiograph before antifungal therapy is stopped.
::::* 1.1.1.2 '''Mild to moderate:'''
:::::* Treatment is usually unnecessary
:::::* Preferred regimen for patients who continue to have symptoms for >1 month: [[Itraconazole]] (200 mg tid for 3 days {{then} 200 mg qd {{or}} bid for 6–12 weeks)
:::::* Note (1): Antifungal treatment is unnecessary in patients with mild symptoms caused by acute pulmonary histoplasmosis
:::* 1.1.2 '''Chronic cavitary pulmonary histoplasmosis:'''
::::* Preferred regimen: [[Itraconazole]] (200 mg tid for 3 days and {{then}} qd or bid for at least 1 year) is recommended
::::* Note (1): Blood levels of itraconazole should be obtained after the patient has been receiving this agent for at least 2 weeks to ensure adequate drug exposure
::::* Note (2): Patients with underlying emphysema often develop progressive pulmonary disease, which is characterized by cavities with surrounding inflammation after infection with hysotplasma capsulatum
:::* 1.1.3 '''Broncholithiasis'''
::::* Antifungal treatment is not recommended
::::* Note: Bronchoscopic or surgical removal of the broncholith is recommended
:::* 1.1.4 '''Pulmonary nodules (Histoplasmomas)'''
::::* Antifungal treatment is not recommended**
::::* Note: There is no evidence that antifungal agents have any effect on histoplasmomas or that histoplasmomas contain viable organisms.
::* 1.2 '''Mediastinitis'''
:::* 1.2.1 '''Mediastinal lymphadenitis'''
::::* 1.2.1.1 '''Asymptomatic cases'''
:::::* Treatment is usually unnecessary
::::* 1.2.1.2 '''Patients who have symptoms that warrant treatment with corticosteroids and in those who continue to have symptoms for > 1 month'''
:::::* [[Itraconazole]] (200 mg 3 tid for 3 days and {{then}} 200 mg qd or bid for 6–12 weeks)
::::* 1.2.1.2 '''Severe cases with obstruction or compression of contiguous structures'''
:::::* Preferred regimen: [[Prednisone]] (0.5–1.0 mg/kg qd [maximum 80 mg qd] in tapering doses over 1–2 weeks)
:::::* Note (1): Antifungal treatment is unnecessary in most patients with symptoms due to mediastinal lymphadenitis
:::::* Note (2): Itraconazole is recommended for 6–12 weeks to reduce the risk of progressive disseminated disease caused by corticosteroid-induced immunosuppression in patients who are given corticosteroids and in patients whose symptoms last longer than 1 month.
:::* 1.2.2 '''Mediastinal granuloma'''
::::* 1.2.2.1 '''Asymptomatic cases'''
:::::* Treatment is usually unnecessary
::::* 1.2.2.2 '''Symptomatic cases'''
:::::* Preferred regimen: [[Itraconazole]] (200 mg 3 times qd for 3 days and {{then}} qd or bid for 6–12 weeks)
:::::* Note (1): [[Itraconazole]] is appropriate for symptomatic cases but there are no controlled trials to prove its efficacy.
:::::* Note (2): There is no evidence that mediastinal granuloma evolves into mediastinal fibrosis. Thus treatment with either surgery or itraconazole should not be used to prevent the development of mediastinal fibrosis
:::* 1.2.3 '''Mediastinal fibrosis'''
::::* Antifungal treatment is not recommended**
:::* 1.2.3.1 '''If clinical findings cannot differentiate mediastinal fibrosis from mediastinal granuloma'''
::::* Preferred regimen: [[Itraconazole]] (200 mg qd or bid for 12 weeks)
::::* Note: The placement of intravascular stents is recommended for selected patients with pulmonary vessel obstruction
::::* Note (2): Mediastinal fibrosis is characterized by invasive fibrosis that encases mediastinal or hilar nodes and that is defined by occlusion of central vessels and airways
::* 1.3 '''Pericarditis:'''
:::* 1.3.1 '''Mild cases'''
::::* Preferred regimen: Nonsteroidal anti-inflammatory therapy
:::* 1.3.2 '''Patients with evidence of hemodynamic compromise or unremitting symptoms after several days of therapy with nonsteroidal anti-inflammatory therapy'''
::::* [[Prednisone]] (0.5–1.0 mg/kg qd [maximum, 80 mg qd] in tapering doses over 1–2 weeks)
:::* 1.3.3 '''If corticosteroids are administered'''
::::* Preferred regimen: [[Itraconazole]] (200 mg tid for 3 days and {{then}} qd or bid for 6–12 weeks)
::::* Note (1): Pericardial fluid removal is indicated for patients with hemodynamic compromise.
::::* Note (2): Pericarditis occurs as a complication of inflammation in adjacent mediastinal lymph nodes in patients with acute pulmonary histoplasmosis.
::* 1.4 '''Central nervous system histoplasmosis'''
:::* Preferred regimen: Liposomal [[Amphotericin B]] (5.0 mg/kg qd for a total of 175 mg/kg given over 4–6 weeks) followed by [[Itraconazole]] (200 mg 2 or 3 times qd) for at least 1 year and until resolution of cerebro spinal fluid abnormalities including Histoplasma antigen levels.
:::* Note: Blood levels of Itraconazole should be obtained to ensure adequate drug exposure
::* 1.5 '''Rheumatologic syndromes'''
:::* 1.5.1 '''Mild cases'''
::::* Preferred regimen: Nonsteroidal anti-inflammatory therapy
:::* 1.5.2 '''Severe cases'''
::::* Preferred regimen: [[Prednisone]] (0.5–1.0 mg/kg qd [maximum, 80 mg qd] in tapering doses over 1–2 weeks)
:::* 1.5.3 '''Corticosteroids administration'''
::::* [[Itraconazole]] (200 mg 3 times tid for 3 days and {{then}} qd or bid for 6–12 weeks)
::::* Note (1): If corticosteroids are used, concurrent itraconazole treatment is recommended to reduce the risk of progressive infection
::::* Note (2): Bone or joint involvement is very rare in progressive disseminated histoplasmosis but it should not be overlooked.
::* 1.6 '''Progressive disseminated histoplasmosis'''
:::* 1.6.1 '''Moderately severe to severe disease'''
::::* Preferred regimen: Liposomal [[Amphotericin B]] (3.0 mg/kg qd) is recommended for 1–2 weeks followed by oral [[Itraconazole]] (200 mg 3 times qd for 3 days and {{then}} 200 mg bid for a total of at least 12 months)
::::* Note (1): Substitution of another lipid formulation at a dosage of 5.0 mg/kg qd may be preferred in some patients because of cost or tolerability
::::* Note (2): The deoxycholate formulation of Amphotericin B (0.7–1.0 mg/kg qd) is an alternative to a lipid formulation in patients who are at a low risk for nephrotoxicity
:::* 1.6.2 '''Immunosupressed patients'''
::::* Lifelong suppressive therapy with [[Itraconazole]] (200 mg qd)
:::* 1.6.3 '''Mild to moderate disease'''
::::* [[Itraconazole]] (200 mg tid for 3 days and then bid qid for at least 12 months)
::::* Note (1): Lifelong suppressive therapy with itraconazole (200 mg daily) may be required in immunosuppressed patients if immunosuppression cannot be reversed and in patients who relapse despite receipt of appropriate therapy
::::* Note (2): Blood levels of itraconazole should be obtained to ensure adequate drug exposure
::::* Note (3): Antigen levels should be measured during therapy and for 12 months after therapy is ended to monitor for relapse. Persistent low-level antigenuria may not be a reason to prolong treatment in patients who have completed appropriate therapy and have no evidence of active infection.
::::* Note (4): Progressive disseminated histoplasmosis is fatal without therapy and treatment with either Amphotericin B or Itraconazole is highly effective. Among patients with AIDS and moderately severe to severe disseminated histoplasmosis, the rate of response was higher (88% vs. 64%) and the mortality rate was lower (2% vs. 13%) among recipients of liposomal amphotericin B (3 mg/kg qd for 1–2 weeks) than among recipients of the deoxycholate formulation.
::* 1.7 '''Prophylaxis recommended for immunosuppressed patients'''
:::* Preferred regimen: [[Itraconazole]] (200 mg qd) in patients with HIV infection with CD4 cell counts <150 cells/mm3 in specific areas of endemicity where the incidence of histoplasmosis is >10 cases per 100 patient-years
:::* Note: Prophylaxis with Itraconazole (200 mg qd) may be appropriate in specific circumstances in other immunosuppressed patients
::* 1.8 '''Performance Measures'''
:::* Preferred regimen: [[Itraconazole]] is the preferred azole for initial therapy for patients with mild-to-moderate histoplasmosis and as step-down therapy after receipt of [[Amphotericin B]]
:::* Note: When other azole agents are used, the medical record should document the specific reasons that Itraconazole was not used and why other azoles were used.
:::* 14.1 '''Severe or moderately severe histoplasmosis'''
:::* Preferred regimen: [[Amphotericin B]]
:::* Note: When Amphotericin B is used the patient's electrolyte level renal function and blood cell count should be monitored several times per week and documented in the medical record.
:::* Note (2): Itraconazole drug levels should be measured during the first month in patients with disseminated or chronic pulmonary histoplasmosis and these levels should be documented in the medical record as well as the physician's response to levels that are too low.
:::* Note (3): Itraconazole should not be given to patients receiving contraindicated medications (i.e., pimozide, quinidine, dofetilide, lovastatin, simvastatin, midazolam, and triazolam). Reasons for deviation from this practice should be documented in the medical record.
::* 2. '''Pregnancy treatment'''
::::* Preferred regimen: Lipid formulation [[Amphotericin B]] (3.0–5.0 mg/kg qd for 4–6 weeks) is recommended
::::* Prefered regimen low risk for nephrotoxicity: The deoxycholate formulation of [[Amphotericin B]] (0.7–1.0 mg/kg qd) is an alternative to a lipid formulation
::::* Note (1): If the newborn shows evidence for infection, treatment is recommended with [[Amphotericin B]] deoxycholate (1.0 mg/kg daily for 4 weeks)
::::* Note (2): Unique issues in pregnancy include the risk of teratogenic complications of azole therapy and of transplacental transmission of Histoplasma capsulatum to the fetus
::* 3. '''Children treatment'''
::::* 3.1 '''Acute pulmonary histoplasmosis'''
::::* Treatment indications and regimens are similar to those for adults, except that [[Amphotericin B]] deoxycholate (1.0 mg/kg daily) is usually well tolerated and the lipid preparations are not preferred
::::* Note: [[Itraconazole]] dosage: 5.0–10.0 mg/kg daily in 2 divided doses (not to exceed 400 mg daily), generally using the solution formulation
::::* '''Progressive disseminated histoplasmosis'''
::::* Prefered regimen: [[Amphotericin B]] deoxycholate (1.0 mg/kg qd for 4–6 weeks)
::::* Alternative regimen: [[Amphotericin B]] deoxycholate (1.0 mg/kg qd for 2–4 weeks) followed by itraconazole (5.0–10.0 mg/kg qd in 2 divided doses) to complete 3 months of therapy.
::::* '''Immunosuppressed patients if immunosuppression cannot be reversed and patients in relapse despite appropiate therapy'''
::::: Preferred regimen: Lifelong suppressive therapy with [[Itraconazole]] (5.0 mg/kg qd up to 200 mg qd)
::::* Note (1): Longer therapy may be needed for patients with severe disease, immunosuppression, or primary immunodeficiency syndromes
::::* Note (2): Blood levels of itraconazole should be obtained to ensure adequate drug exposure
::::* Note (3): Antigen levels should be monitored during therapy and for 12 months after therapy is ended to monitor for relapse. Persistent low-level antigenuria may not be a reason to prolong treatment in patients who have completed appropriate therapy and have no evidence of active infection.

:::::* Obtain a reference haematocrit before fluid therapy. Give only isotonic solutions such as 0.9% saline, Ringer’s lactate, or Hartmann’s solution. Start with 5–7 ml/ kg/hour for 1–2 hours, then reduce to 3–5 ml/kg/hr for 2–4 hours, and then reduce to 2–3 ml/kg/hr or less according to the clinical response
::* Note(1): Albendazole and Mebendazole are contraindicated during pregnancy and not recommended in children aged 2 years.
:::::* Reassess the clinical status and repeat the haematocrit. If the haematocrit remains the same or rises only minimally, continue with the same rate (2–3 ml/kg/hr) for another 2–4 hours. If the vital signs are worsening and haematocrit is rising rapidly, increase the rate to 5–10 ml/kg/hour for 1–2 hours. Reassess the clinical status, repeat the haematocrit and review fluid infusion rates accordingly
::* Note(2): Prednisone administered at a dose of 30 mg/day to 60 mg/day for 10 to 15 days for severe symptoms
:::::* Give the minimum intravenous fluid volume required to maintain good perfusion and urine output of about 0.5 ml/kg/hr. Intravenous fluids are usually needed for only 24–48 hours. Reduce intravenous fluids gradually when the rate of plasma leakage decreases towards the end of the critical phase. This is indicated by urine output and/or oral fluid intake that is/are adequate, or haematocrit decreasing below the baseline value in a stable patient
:::::* Patients with warning signs should be monitored by health care providers until the period of risk is over. A detailed fluid balance should be maintained. Parameters that should be monitored include vital signs and peripheral perfusion (1–4 hourly until the patient is out of the critical phase), urine output (4–6 hourly), haematocrit (before and after fluid replacement, then 6–12 hourly), blood glucose, and other organ functions (such as renal profile, liver profile, coagulation profile, as indicated)
::::* 3.2 '''Without warning signs'''
:::::* Encourage oral fluids. If not tolerated, start intravenous fluid therapy of 0.9% saline or Ringer’s lactate with or without dextrose at maintenance rate. For obese and overweight patients, use the ideal body weight for calculation of fluid infusion. Patients may be able to take oral fluids after a few hours of intravenous fluid therapy. Thus, it is necessary to revise the fluid infusion frequently. Give the minimum volume required to maintain good perfusion and urine output. Intravenous fluids are usually needed only for 24–48 hours
:::::* Patients should be monitored by health care providers for temperature pattern, volume of fluid intake and losses, urine output (volume and frequency), warning signs, haematocrit, and white blood cell and platelet counts.

:::::* Start intravenous fluid resuscitation with isotonic crystalloid solutions at 5–10 ml/kg/hour over one hour. Then reassess the patient’s condition (vital signs, capillary refill time, haematocrit, urine output). The next steps depend on the situation
:* This regimen is still under investigation, but it appears to be as effective as [[Praziquantel]].
:::::* If the patient’s condition improves, intravenous fluids should be gradually reduced to 5–7 ml/kg/hr for 1–2 hours, then to 3–5 ml/kg/hr for 2–4 hours, then to 2–3 ml/kg/hr, and then further depending on haemodynamic status, which can be maintained for up to 24–48 hours
:*Note: Urgent biliary decompression might be required for patients with acute cholangitis.
:::::* If vital signs are still unstable (i.e. shock persists), check the haematocrit after the first bolus. If the haematocrit increases or is still high (>50%), repeat a second bolus of crystalloid solution at 10–20 ml/kg/hr for one hour. After this second bolus, if there is improvement, reduce the rate to 7–10 ml/ kg/hr for 1–2 hours, and then continue to reduce as above. If haematocrit decreases compared to the initial reference haematocrit (<40% in children and adult females, <45% in adult males), this indicates bleeding and the need to cross-match and transfuse blood as soon as possible

If the condition is still unstable, repeat the haematocrit after the second bolus
:::::* If the haematocrit decreases compared to the previous value (<40% in children and adult females, less than 45% in adult males), this indicates bleeding and the need to cross-match and transfuse blood as soon as possible (see treatment for haemorrhagic complications). If the haematocrit increases compared to the previous value or remains very high ( more than 50%), continue colloid solutions at 10–20 ml/kg as a third bolus over one hour.

:*Preferred regimen: [[Triclabendazole]] 10 mg/kg PO one dose<ref>{{Cite web | title =Parasites - Fascioliasis| url = http://www.cdc.gov/parasites/fasciola/health_professionals/}}</ref>
::::* Blood transfusion required
:*Note: Two-dose (double-dose) triclabendazole therapy can be given to patients who have severe or heavy Fasciola infections (many parasites) or who did not respond to single-dose therapy.
:::::* Give 5–10ml/kg of fresh-packed red cells or 10–20 ml/kg of fresh whole blood at an appropriate rate and observe the clinical response. It is important that fresh whole blood or fresh red cells are given. Oxygen delivery at tissue level is optimal with high levels of 2,3 di-phosphoglycerate (2,3 DPG). Stored blood loses 2,3 DPG, low levels of which impede the oxygen-releasing capacity of haemoglobin, resulting in functional tissue hypoxia. A good clinical response includes improving haemodynamic status and acid-base balance
:*Alternative regimen: [[Nitazoxanide]] 500mg PO bid for 7 days
:::::* Consider repeating the blood transfusion if there is further blood loss or no appropriate rise in haematocrit after blood transfusion. There is little evidence to support the practice of transfusing platelet concentrates and/or fresh-frozen plasma for severe bleeding. It is being practised when massive bleeding can not be managed with just fresh whole blood/fresh-packed cells, but it may exacerbate the fluid overload
:::::* Great care should be taken when inserting a naso-gastric tube which may cause severe haemorrhage and may block the airway. A lubricated oro-gastric tube may minimize the trauma during insertion. Insertion of central venous catheters should be done with ultra-sound guidance or by a very experienced person

::::* Oxygen therapy should be given immediately
:*Alternative regimen (1): [[Bithinol]] 30-50mg/kg PO on alternate days for 10-15 doses
::::* When the following signs are present, intravenous fluids should be discontinued or reduced to the minimum rate necessary to maintain euglycaemia
:*Alternative regimen (2): [[Niclosamide]] 2mg/kg PO single dose
:::::* signs of cessation of plasma leakage; stable blood pressure, pulse and peripheral perfusion; haematocrit decreases in the presence of a good pulse volume; afebrile for more than 24–48 days (without the use of antipyretics); resolving bowel/abdominal symptoms; improving urine output
::::* The management of fluid overload varies according to the phase of the disease and the patient’s haemodynamic status. If the patient has stable haemodynamic status and is out of the critical phase (more than 24–48 hours of defervescence), stop intravenous fluids but continue close monitoring. If necessary, give oral or intravenous furosemide 0.1–0.5 mg/kg/dose once or twice daily, or a continuous infusion of furosemide 0.1 mg/kg/hour. Monitor serum potassium and correct the ensuing hypokalaemia
::::* If the patient has stable haemodynamic status but is still within the critical phase, reduce the intravenous fluid accordingly. Avoid diuretics during the plasma leakage phase because they may lead to intravascular volume depletion
::::* Patients who remain in shock with low or normal haematocrit levels but show signs of fluid overload may have occult haemorrhage. Further infusion of large volumes of intravenous fluids will lead only to a poor outcome. Careful fresh whole blood transfusion should be initiated as soon as possible. If the patient remains in shock and the haematocrit is elevated, repeated small boluses of a colloid solution may help

::::* Both hyperglycaemia and hypoglycaemia may occur, even in the absence of diabetes mellitus and/or hypoglycaemic agents. Electrolyte and acid-base imbalances are also common observations in severe dengue and are probably related to gastrointestinal losses through vomiting and diarrhoea or to the use of hypotonic solutions for resuscitation and correction of dehydration. Hyponatraemia, hypokalaemia, hyperkalaemia, serum calcium imbalances and metabolic acidosis (sodium bicarbonate for metabolic acidosis is not recommended for pH ≥ 7.15) can occur.

::* 1.1. '''Prevention'''
::*Alternative regimen (2): [[Mefloquine]] 250 mg PO single dose
:::* No WNV vaccines are licensed for use in humans. In the absence of a vaccine, prevention of WNV disease depends on community-level mosquito control programs to reduce vector densities, personal protective measures to decrease exposure to infected mosquitoes, and screening of blood and organ donors.
::*Note: There is no benefit in associating the alternative therapies to Praziquantel.
:::* Personal protective measures include use of mosquito repellents, wearing long-sleeved shirts and long pants, and limiting outdoor exposure from dusk to dawn. Using air conditioning, installing window and door screens, and reducing peridomestic mosquito breeding sites, can further decrease the risk for WNV exposure.
:::* Blood and some organ donations in the United States are screened for WNV infection; health care professionals should remain vigilant for the possible transmission of WNV through blood transfusion or organ transplantation. Any suspected WNV infections temporally associated with blood transfusion or organ transplantation should be reported promptly to the appropriate state health department.
::* 1.2. '''Treatment'''
:::* There is no specific treatment for WNV disease; clinical management is supportive. Patients with severe meningeal symptoms often require pain control for headaches and antiemetic therapy and rehydration for associated nausea and vomiting. Patients with encephalitis require close monitoring for the development of elevated intracranial pressure and seizures. Patients with encephalitis or poliomyelitis should be monitored for inability to protect their airway. Acute neuromuscular respiratory failure may develop rapidly and prolonged ventilatory support may be required.

::* 4 '''Prevention  of  varicella zoster virus (VZV) Infections in HIV-Infected Adults and Adolescents'''
:::* 4.1 '''Pre-Exposure Prevention of VZV Primary Infection'''
::::* '''Indications'''
:::::* Adult and adolescent patients with CD4 count ≥200 cells/mm3 without documentation of vaccination, health-care provider diagnosis or verification of a history of varicella or herpes zoster, laboratory confirmation of disease, or persons who are seronegative for VZV. Routine VZV serologic testing in HIV-infected adults and adolescents is not recommended.
:::::* '''Vaccination'''
:::::* Primary varicella vaccination (Varivax™), 2 doses (0.5 mL SQ) administered 3 months apart
:::::* If vaccination results in disease because of vaccine virus, treatment with acyclovir is recommended.
:::::* VZV-susceptible household contacts of susceptible HIV-infected persons should be vaccinated to prevent potential transmission of VZV to their HIV-infected contacts.
:::::* If post-exposure VariZIG has been administered, wait at least 5 months before varicella vaccination.
:::::* If post-exposure acyclovir has been administered, wait at least 3 days before varicella vaccine.
:::* 4.2 '''Post-Exposure Prophylaxis'''
::::* '''Indication'''
:::::* Close contact with a person who has active varicella or herpes zoster, and
:::::* Is susceptible to VZV (i.e., has no history of vaccination or of either condition, or is known to be VZV seronegative)
::::* Preferred regimen: VariZIG 125 IU /10 kg (maximum of 625 IU) IM, administered as soon as possible and within 10 days after exposure to a person with active varicella or herpes zoster
::::* Alternative regimen (Begin 7–10 Days After Exposure): [[Acyclovir]] 800 mg PO 5 times/day for 5–7 days {{or}} [[Valacyclovir]] 1 g PO tid for 5–7 days 
::::* If post-exposure VariZIG has been administered, wait at least 5 months before varicella vaccination.
::::* Note: Patients receiving monthly high dose IVIG (i.e., >400 mg/kg) are likely to be protected against VZV and probably do not require VariZIG if the last dose of IVIG was administered <3 weeks before VZV exposure.
::::* Note: Neither these pre-emptive interventions nor post-exposure varicella vaccination have been studied in HIV-infected adults and adolescents.
::::* If acyclovir or valacyclovir is used, varicella vaccines should not be given until at least 72 hours after the last dose of the antiviral drug.

::* 1.'''Preferred regimen for External Anogenital Warts'''(i.e., penis, groin, scrotum, vulva, perineum, external anus, and perianus)
:::* 1.1 '''Patient-Applied''': [[Imiquimod]] 3.75% or 5% cream {{or}} [[Podofilox]] 0.5% solution or gel {{or}} [[Sinecatechins]] 15% ointment
:::* 1.2 '''Provider-Administered''': Cryotherapy with liquid nitrogen or cryoprobe  {{or}} Surgical removal either by tangential scissor excision, tangential shave excision, curettage, laser,or electrosurgery {{or}} [[Trichloroacetic acid]] (TCA) {{or}} Bichloroacetic acid (BCA) 80%-90% solution
:::* Note (1): Many persons with external anal warts also have intra-anal warts. Thus, persons with external anal warts might benefit from an inspection of the anal canal by digital examination, standard anoscopy, or high-resolution anoscopy.
:::* Note (2): Might weaken condoms and vaginal diaphragms.
::* 2.'''Alternative Regimens for External Genital Warts'''
:::* 2.1 '''Urethral Meatus Warts'''
::::* Preferred regimen: Cryotherapy with liquid nitrogen {{or}} Surgical removal
:::* 2.2 '''Vaginal Warts'''
::::* Preferred regimen: Cryotherapy with liquid nitrogen {{or}} Surgical removal  {{or}}  (TCA {{or}} BCA 80%–90% solution)
::::* Note: The use of a cryoprobe in the vagina is not recommended because of the risk for vaginal perforation and fistula formation
:::* 2.3 '''Cervical Warts'''
::::* Preferred regimen: Cryotherapy with liquid nitrogen {{or}} Surgical removal {{or}} (TCA {{or}} BCA 80%–90% solution)
::::* Note: Management of cervical warts should include consultation with a specialist.For women who have exophytic cervical warts, a biopsy evaluation to exclude high-grade SIL must be performed before treatment is initiated.
:::* 2.4 '''Intra-anal Warts'''
::::* Preferred regimen: Cryotherapy with liquid nitrogen {{or}} Surgical removal {{or}} (TCA {{or}} BCA 80%–90% solution)
::::* Note: Management of intra-anal warts should include consultation with a specialist.


::::* Alternative regimen (2): Less effective is [[Crotamiton]] 10% cream, apply for 24 hours, rinse off, then reapply for 24 hours.  
::* 3. '''Specific considerations'''
:::* 3.1 '''Follow-up'''
::::* Most anogenital warts respond within 3 months of therapy. Factors that might affect response to therapy include immunosuppression and treatment compliance. In general, warts located on moist surfaces or in intertriginous areas respond best to topical treatment. A new treatment modality should be selected when no substantial improvement is observed after a complete course of treatment or in the event of severe side effects; treatment response and therapy-associated side effects should be evaluated throughout the course of therapy.


:::* 2. '''AIDS patients (CD4 <150 per mm3), debilitated or developmentally disabled patients '''
:::* 3.2 '''Management of sex partners'''
::::* Persons should inform current partner(s) about having genital warts because the types of HPV that cause warts can be passed on to partners. Partners should receive counseling messages that partners might already have HPV despite no visible signs of warts, so HPV testing of sex partners of persons with genital warts is not recommended.


:::: * preferred regimen (for Norwegian scabies) : [[Permethrin]] 5% cream-2 or more applications a week apart may be needed. After each [[Permethrin]] dose (days 2-7) apply 6% [[Sulfur]] in petrolatum.
:::* 3.3 '''Pregnancy'''
::::* [[Podofilox]] (podophyllotoxin), [[Podophyllin]], and [[Sinecatechins]] should not be used during pregnancy. Imiquimod appears to pose low risk but should be avoided until more data are available.
::::* Cesarean delivery is indicated for women with anogenital warts if the pelvic outlet is obstructed or if vaginal delivery would result in excessive bleeding.
::::* Pregnant women with anogenital warts should be counseled concerning the low risk for warts on the larynx of their infants or children (recurrent respiratory papillomatosis).


::::: Note: Apply entire skin from chin down to and including toes with [[Permethrin]] 5% cream. Leave on 8–14hours. Repeat if itching persists for >2-4 wks after treatment or new pustules occur.
:::* 3.4 '''HIV infection'''
::::* Data do not support altered approaches to treatment for persons with HIV infection.
::::* Squamous cell carcinomas arising in or resembling anogenital warts might occur more frequently among immunosuppressed persons, therefore requiring biopsy for confirmation of diagnosis for suspicious cases


::::* Alternative regimen: [[Ivermectin]] 200 mcg/kg PO once is reported effective; may need 2 or more doses separated by 14 days.
:::* 3.5 '''High-grade squamous intraepithelial lesions'''
::::* Biopsy of an atypical wart might reveal HSIL or cancer of the anogenital tract. In this instance, referral to a specialist for treatment is recommended.


::::: Note: Norwegian scabies in AIDS patients is extensive, crusted. Can mimic psoriasis and not pruritic but highly contagious—isolate.

::* 1.1. '''Prevention'''
:::* 1.1.1. '''Vaccines'''
::::* Note (1): Measles can be prevented with measles-containing vaccine, which is primarily administered as the combination measles-mumps-rubella (MMR) vaccine. The combination measles-mumps-rubella-varicella (MMRV) vaccine can be used for children aged 12 months through 12 years for protection against measles, mumps, rubella and varicella. Single-antigen measles vaccine is not available.
::::* Note (2): Vaccination recommendations
:::::* Children: CDC recommends routine childhood immunization for MMR vaccine starting with the first dose at 12 through 15 months of age, and the second dose at 4 through 6 years of age or at least 28 days following the first dose.
:::::* Students at post-high school educational institutions: Students at post-high school educational institutions without evidence of measles immunity need two doses of MMR vaccine, with the second dose administered no earlier than 28 days after the first dose.
:::::* Adults: People who are born during or after 1957 who do not have evidence of immunity against measles should get at least one dose of MMR vaccine.
:::::* International travelers: People 6 months of age or older who will be traveling internationally should be protected against measles. Before travelling internationally,
::::::* Infants 6 through 11 months of age should receive one dose of MMR vaccine
::::::* Children 12 months of age or older should have documentation of two doses of MMR vaccine (the first dose of MMR vaccine should be administered at age 12 months or older; the second dose no earlier than 28 days after the first dose)
::::::* Teenagers and adults born during or after 1957 without evidence of immunity against measles should have documentation of two doses of MMR vaccine, with the second dose administered no earlier than 28 days after the first dose
:::* 1.1.2. '''Post-exposure Prophylaxis'''
::::* 1.1.2.1. '''Indication'''
:::::* People exposed to measles who cannot readily show that they have evidence of immunity against measles should be offered post-exposure prophylaxis (PEP) or be excluded from the setting (school, hospital, childcare). MMR vaccine, if administered within 72 hours of initial measles exposure, or immunoglobulin (IG), if administered within six days of exposure, may provide some protection or modify the clinical course of disease.
::::* Note (1): If MMR vaccine is not administered within 72 hours of exposure as PEP, MMR vaccine should still be offered at any interval following exposure to the disease in order to offer protection from future exposures. People who receive MMR vaccine or IG as PEP should be monitored for signs and symptoms consistent with measles for at least one incubation period.
::::* Note (2): If many measles cases are occurring among infants younger than 12 months of age, measles vaccination of infants as young as 6 months of age may be used as an outbreak control measure. Note that children vaccinated before their first birthday should be revaccinated when they are 12 through 15 months old and again when they are 4 through 6 years of age.
::::* Note (3): People who are at risk for severe illness and complications from measles, such as infants younger than 12 months of age, pregnant women without evidence of measles immunity, and people with severely compromised immune systems, should receive IG. Intramuscular IG (IGIM) should be given to all infants younger than 12 months of age who have been exposed to measles.
::::* Note (4):  For infants aged 6 through 11 months, MMR vaccine can be given in place of IG, if administered within 72 hours of exposure. Because pregnant women might be at higher risk for severe measles and complications, intravenous IG (IGIV) should be administered to pregnant women without evidence of measles immunity who have been exposed to measles. People with severely compromised immune systems who are exposed to measles should receive IGIV regardless of immunologic or vaccination status because they might not be protected by MMR vaccine.
::::* Preferred regimen: The recommended dose of IGIM is 0.5 mL/kg of body weight (maximum dose = 15 mL) and the recommended dose of IGIV is 400 mg/kg.
::::* Note (5): If a healthcare provider without evidence of immunity is exposed to measles, MMR vaccine should be given within 72 hours, or IG should be given within 6 days when available. Exclude healthcare personnel without evidence of immunity from duty from day 5 after first exposure to day 21 after last exposure, regardless of post-exposure vaccine.
::* 1.2. '''Treatment'''
:::* Note (1): There is no specific antiviral therapy for measles. Medical care is supportive and to help relieve symptoms and address complications such as bacterial infections.
:::* Note (2): Severe measles cases among children, such as those who are hospitalized, should be treated with vitamin A. Vitamin A should be administered immediately on diagnosis and repeated the next day. The recommended age-specific daily doses are
::::* 50,000 IU for infants younger than 6 months of age
::::* 100,000 IU for infants 6–11 months of age
::::* 200,000 IU for children 12 months of age and older

{{PBI|BK virus}}
:* '''Human polyomavirus (BK virus) treatment'''
::* '''Maintenance regimen consisting of triple immunosuppression therapy''': [[Calcineurin]] inhibitor ([[Cyclosporine]] or [[Tacrolimus]]) {{and}} an antimetabolite ([[Azathioprine]], [[Mycophenolate mofetil]], or [[Mycophenolate sodium]]), {{and}} [[Prednisone]] is to discontinue completely the antimetabolite (usually [[Mycophenolate]]) and decrease the dose of the [[Calcineurin]] inhibitor.
::* '''Alternative regimen (1)''': Decrease the [[Mycophenolate]] dose by 50 percent, followed by a 50 percent decrease in the [[Calcineurin]] inhibitor at three months if decoy cells persist. If using this approach, the target serum [[Tacrolimus]] trough level is 4 to 6, and the target serum [[Cyclosporine]] trough level is 60 to 100 ng/mL. [[Mycophenolate]] may be discontinued completely if viral activation persists. Maintenance immunosuppression then consists of [[Tacrolimus]] and low-dose [[Prednisone]].
::* '''Alternative regimen (2)''': Reduce both the [[Calcineurin]] inhibitor and the [[Mycophenolate]], which allows both the targeting of two pathways and lower total immunosuppression.
:::* Note (1): For those who are hypogammaglobulinemic, we administer intravenous immunoglobulins (IV IG) in replacement doses of 500 mg/kg. Quantitative immunoglobulins should be checked two to three months later to determine whether hypogammaglobulinemia has recurred. Intravenous immunoglobulins (IV IG) is also an option in certain settings, based upon polymerase chain reaction (PCR) and kidney biopsy results. IVIG may contain antibodies against BK and JC virus since these viruses are ubiquitous in the general population.
:::* Note (2): The goals of decreased immunosuppressive therapy are to restrain viral replication without triggering rejection.
:::* Note (3): Reduced immunosuppression (defined as lowering mean doses of [[Mycophenolate]] and [[Tacrolimus]]) resulted in the successful elimination of viremia (mean period of six months) and allograft survival.
:::* Note (4): Alternative approaches to reducing immunosuppression have also been effective
::::* 4.1 Changing from [[Tacrolimus]] to low-dose [[Cyclosporine]] not only reduces the effect of the [[Calcineurin]] inhibitor, but also reduces [[Mycophenolate]] concentrations.
::::* 4.2 Replacing the [[Calcineurin]] inhibitor with [[Sirolimus]], with or without discontinuation of the antimetabolite, has the advantage of avoiding the long-term [[Calcineurin]] inhibitor-related nephrotoxic effects.
::::* 4.3 Lowering the dose of [[Calcineurin]] inhibitors may slow the loss of renal function.


:::< Age 2: Adenovirus;
:* '''Primary Regimens'''
::* Decrease immunosuppression if possible. (Cornerstone of Treatment)
::* Suggested antiviral therapy is based on anecdotal data. If progressive renal dysfunction:
::* Fluoroquinolone {{and}} IVIG 500 mg/kg IV {{and}} Leflunomide 100 mg for daily for 3 days, then 10-20 mg PO daily
::* If refractory to all of the above, add [[Cidofovir]] 5 mg/kg once per week for 2 weeks, then once every other week  if refractory to all of the above


:::: Note:Antibiotics indicated only with associated sinusitis or heavy growth on throat culture for S. pneumo., Group A strep, H. influenzae or no improvement in 1 week. Otherwise treatment is symptomatic.
:* '''Ancillary Therapies in BK Virus Nephropathy'''
::* [[Cidofovir]] 0.25-1.0 mg/kg IV biweekly for 8 wk without [[Probenecid]], prehydration recommended
::* [[Leflunomide]] 100 mg loading dose for 3 days, 20-60 mg/day, goal [[Leflunomide]] trough 50-100 ng/mL (consider lower trough goals of 20-40 ng/mL given hemolysis risk)
::* IV Ig 1-2 g/kg IV for 1-2 doses or 150 mg/kg  IV biweekly for 8 wk
::* [[Fluoroquinolones]]-[[Ciproflaxacin]] 500 mg/day, duration dependent on virological response.

::* 1.'''Retinitis'''
:::* 1.1 '''In HIV-infected adults'''
::::* Preferred regimen (1): [[Ganciclovir]] IV


::::* Preferred regimen (2): [[Valganciclovir]] PO
::* Optimize ART in patients who develop Progressive Multifocal Leukoencephalopathy in phase of HIV viremia on ART .


::::* Preferred regimen (3): [[Foscarnet]] IV, [[Cidofovir]] IV {{and}} [[Ganciclovir]] intraocular implant coupled with [[Valganciclovir]].
::* [[Corticosteroids]] may be used for Progressive Multifocal Leukoencephalopathy- immune reconstitution inflammatory syndrome (IRIS) characterized by contrast enhancement, edema or mass effect, and with clinical deterioration
:::* 1.2 '''In HIV-infected infants and children '''
::::* Initial treatment (induction therapy): [[Ganciclovir]] IV  for acquired CMV disease, including CMV retinitis and other end-organ disseminated CMV disease (e.g., colitis, esophagitis, CNS disease).
:::: Note (1): Oral [[Valganciclovir]], a prodrug of [[Ganciclovir]], is one of the first-line treatments for HIV infected adults with CMV retinitis and is an option in older children who weigh enough to receive the adult dose and tablet formulation of [[Valganciclovir]]. The drug is well absorbed from the GI tract and rapidly metabolized to [[Ganciclovir]] in the intestine and liver.
:::: Note (2): [[Valganciclovir]] oral solution has not been studied in pediatric patients for treatment of CMV retinitis, but consideration can be given to its use for transitioning from [[Ganciclovir]] IV to [[Valganciclovir]] oral to complete treatment and or for secondary prophylaxis once improvement in retinitis is noted.
:::* 1.3 '''An alternative drug for treating CMV disease or for use in [[Ganciclovir]]-resistant CMV infections in HIV infected children''' : [[Foscarnet]].
:::: Note (1): [[Foscarnet]] used as suppressive therapy has been associated with increased length of survival relative to [[Ganciclovir]] in HIV-infected adults. Doses should be modified in patients with renal insufficiency.
:::: Note (2): [[Cidofovir]] is effective in treating CMV retinitis in adults who are intolerant of other therapies.
:::: Note (3): Combination therapy with [[Ganciclovir]] and [[Foscarnet]] delays progression of retinitis in certain patients in whom monotherapy fails and can be used as initial therapy in children with sight-threatening disease.
:::: Note (4): Combination therapy also has been used for adults with retinitis that has relapsed on single-agent therapy.


::* 2. '''In Transplant patients'''
{{PBI|Rabies}}
:::* Preferred regimen: [[Valganciclovir]]
:* Rabies treatment
:::: Note (1): Use of [[Valganciclovir]] to prevent infections in CMV seronegative recipients who receive organs from a seropositive donor and in seropositive receivers has been highly effective.
::* Preferred regimen: no specific therapetics agents are available once the disease is established.
:::: Note (2): Others suggest preemptive treatment when pt develops CMV antigenemia or positive PCR post-transplant.
::* Note: There are vaccines and immunoglobulins available for postexposure prophylaxis

:::* '''Preferred regimen (2)''': [[Valganciclovir]] 900 mg PO q12h for 14–21 days, then 900 mg PO q24h for maintenance therapy
:::* Alternative regimen: [[Ganciclovir]] 5 mg/kg IV q12h for 14–21 days ,[[Ganciclovir]] as with retinitis except induction period extended for 3–6 wks (No agreement on use of maintenance; may not be necessary except after relapse. Responses less predictable than for retinitis.), then [[Valganciclovir]] 900 mg PO q24h {{or}} [[Foscarnet]] 60 mg/kg IV q8h or 90 mg/kg IV q12h for 14–21 days, then 90–120 mg/kg IV q24h {{or}} [[Cidofovir]] 5 mg/kg IV for 2wks, then 5 mg/kg every other wk; each dose should be administered with IV saline hydration {{and}} oral probenecid {{or}} repeated intravitreal injections with [[Fomivirsen]] (for relapses only, not as initial therapy)
:::: Note (1): Diagnosis by biopsy of ulcer base or edge  with demonstration of CMV inclusions and other pathogen.
:::: Note (2): Switch to oral [[Valganciclovir]] when PO tolerated & when symptoms not severe enough to interfere with absorption.
:::: Note (3): Antiretroviral therapy is essential in long term suppression.


::* 4. '''Pneumonia'''
Wound cleansing, human rabies immunoglobulin - administer full dose infiltrated around any wound. Administer any remaining volume IM at other site anatomically distant from the wound. Administer vaccine 1.0 ml, IM at deltoid area one each on days 0, 3, 7 and 14.
:::* Preferred regimen: : [[Valganciclovir]] 900 mg PO q12h for 14–21 days, then 900 mg PO q24h for maintenance therapy

::: Providing intravenous fluids (IV) and balancing electrolytes (body salts).
::: Maintaining oxygen status and blood pressure
::: Treating other infections if they occur.
:::: Note (1): No FDA-approved vaccine or medicine (e.g., antiviral drug) is available for Ebola.
:::: Note (2):  Recovery from Ebola depends on good supportive care and the patient’s immune response.
:::: Note (3): People who recover from Ebola infection develop antibodies that last for at least 10 years, possibly longer. It is not known if people who recover are immune for life or if they can become infected with a different species of Ebola.
:::: Note (4): Some people who have recovered from Ebola have developed long-term complications, such as joint and vision problems.

::* Supportive therapy
::* Access to safe drinking-water
:::* ICU management should include careful assessment, monitoring and adjustment of volume status and cardiac function, including inotropic and vasopressor support if needed.
::* Use of improved sanitation
:::* Fluids should be administered carefully due to the potential for capillary leakage.
::* Hand washing with soap
:::* Supplemental oxygen should be administered if patients become hypoxic.
:::* Equipment and materials for intubation and mechanical ventilation should be readily available since onset of respiratory failure may be precipitous.

:::* These are patients who are able to tolerate adequate volumes of oral fluids and pass urine at least once every six hours, and do not have any of the warning signs, particularly when fever subsides
==Smallpox==
:::* Patients who are sent home should be monitored daily by health care providers for temperature pattern, volume of fluid intake and losses, urine output (volume and frequency), warning signs, signs of plasma leakage and bleeding, haematocrit, and white blood cell and platelet counts

:* '''Smallpox''' <ref>{{Cite web | title = DIAGNOSIS AND MANAGEMENT OF SMALLPOX | url = http://www.nejm.org/doi/pdf/10.1056/NEJMra020025 }}</ref>
::* Supportive care is the mainstay of therapy.
::* Currently, there are no anti-viral drugs of proven efficacy.
::* Recently, animal studies suggest that [[cidofovir]] and its cyclic analogues, given at the time of or immediately after exposure, have promise for the prevention of cowpox, vaccinia, and monkeypox.
::* Patients need adequate hydration and nutrition, because substantial amounts of fluid and protein can be lost by febrile persons with dense, often weeping lesions.
:::* 1. '''Secondary bacterial infection'''
::::* Penicillinase-resistant antimicrobial agents should be used


::* 2. '''Ambulatory patients  with stable haematocrit can be sent home '''
:::::* If smallpox lesions are secondarily infected,  
:::* Encourage oral intake of oral rehydration solution (ORS), fruit juice and other fluids containing electrolytes and sugar to replace losses from fever and vomiting
:::* Give [[Paracetamol]] for high fever if the patient is uncomfortable. The interval of paracetamol dosing should not be less than six hours. Tepid sponge if the patient still has high fever
:::* Should be brought to hospital immediately if any of the following occur: no clinical improvement, deterioration around the time of defervescence, severe abdominal pain, persistent vomiting, cold and clammy extremities, lethargy or irritability/restlessness, bleeding (e.g. black stools or coffee-ground vomiting), not passing urine for more than 4–6 hours


::* 3. '''Patients who should be referred for in-hospital management'''
:::::* If bacterial infection endangers the eyes
:::* Patients may need to be admitted to a secondary health care centre for close observation, particularly as they approach the critical phase. These include patients with warning signs (Abdominal pain or tenderness, Persistent vomiting, Clinical fluid accumulation, Mucosal bleed, Lethargy, restlessness, Liver enlargment >2cm, Laboratory:increase in HCT concurrent with rapid decrease in platelet count), those with co-existing conditions that may make dengue or its management more complicated (such as pregnancy, infancy, old age, obesity, diabetes mellitus, renal failure, chronic haemolytic diseases), and those with certain social circumstances (such as living alone, or living far from a health facility without reliable means of transport)


::::* 3.1 '''With warning signs'''
::::::* Daily eye rinsing is required in severe cases.  
:::::* Obtain a reference haematocrit before fluid therapy. Give only isotonic solutions such as 0.9% saline, Ringer’s lactate, or Hartmann’s solution. Start with 5–7 ml/ kg/hour for 1–2 hours, then reduce to 3–5 ml/kg/hr for 2–4 hours, and then reduce to 2–3 ml/kg/hr or less according to the clinical response
:::::* Reassess the clinical status and repeat the haematocrit. If the haematocrit remains the same or rises only minimally, continue with the same rate (2–3 ml/kg/hr) for another 2–4 hours. If the vital signs are worsening and haematocrit is rising rapidly, increase the rate to 5–10 ml/kg/hour for 1–2 hours. Reassess the clinical status, repeat the haematocrit and review fluid infusion rates accordingly
:::::* Give the minimum intravenous fluid volume required to maintain good perfusion and urine output of about 0.5 ml/kg/hr. Intravenous fluids are usually needed for only 24–48 hours. Reduce intravenous fluids gradually when the rate of plasma leakage decreases towards the end of the critical phase. This is indicated by urine output and/or oral fluid intake that is/are adequate, or haematocrit decreasing below the baseline value in a stable patient
:::::* Patients with warning signs should be monitored by health care providers until the period of risk is over. A detailed fluid balance should be maintained. Parameters that should be monitored include vital signs and peripheral perfusion (1–4 hourly until the patient is out of the critical phase), urine output (4–6 hourly), haematocrit (before and after fluid replacement, then 6–12 hourly), blood glucose, and other organ functions (such as renal profile, liver profile, coagulation profile, as indicated)
::::* 3.2 '''Without warning signs'''
:::::* Encourage oral fluids. If not tolerated, start intravenous fluid therapy of 0.9% saline or Ringer’s lactate with or without dextrose at maintenance rate. For obese and overweight patients, use the ideal body weight for calculation of fluid infusion. Patients may be able to take oral fluids after a few hours of intravenous fluid therapy. Thus, it is necessary to revise the fluid infusion frequently. Give the minimum volume required to maintain good perfusion and urine output. Intravenous fluids are usually needed only for 24–48 hours
:::::* Patients should be monitored by health care providers for temperature pattern, volume of fluid intake and losses, urine output (volume and frequency), warning signs, haematocrit, and white blood cell and platelet counts. Other laboratory tests (such as liver and renal functions tests) can be done, depending on the clinical picture and the facilities of the hospital or health centre


::* 4. '''Severe dengue'''
::::::* Topical [[idoxuridine]] should be considered for the treatment of corneal lesions, although its efficacy is unproved for smallpox.
:::* Severe dengue: Severe plasma leakage leading to dengue shock and/or fluid accumulation with respiratory distress; severe haemorrhages; severe organ impairment (hepatic damage, renal impairment, cardiomyopathy, encephalopathy or encephalitis)
:::::* If the eruption is very dense and widespread.
:::* 4.1 '''Treatment of shock'''
::::* 4.1.1 '''Compensated shock'''
:::::* Start intravenous fluid resuscitation with isotonic crystalloid solutions at 5–10 ml/kg/hour over one hour. Then reassess the patient’s condition (vital signs, capillary refill time, haematocrit, urine output). The next steps depend on the situation
:::::* If the patient’s condition improves, intravenous fluids should be gradually reduced to 5–7 ml/kg/hr for 1–2 hours, then to 3–5 ml/kg/hr for 2–4 hours, then to 2–3 ml/kg/hr, and then further depending on haemodynamic status, which can be maintained for up to 24–48 hours
:::::* If vital signs are still unstable (i.e. shock persists), check the haematocrit after the first bolus. If the haematocrit increases or is still high (>50%), repeat a second bolus of crystalloid solution at 10–20 ml/kg/hr for one hour. After this second bolus, if there is improvement, reduce the rate to 7–10 ml/ kg/hr for 1–2 hours, and then continue to reduce as above. If haematocrit decreases compared to the initial reference haematocrit (<40% in children and adult females, <45% in adult males), this indicates bleeding and the need to cross-match and transfuse blood as soon as possible
:::::* Further boluses of crystalloid or colloidal solutions may need to be given during the next 24–48 hours


::::* 4.1.2 '''Hypotensive shock'''
==HIV/AIDS==
:::::* Initiate intravenous fluid resuscitation with crystalloid or colloid solution (if available) at 20 ml/kg as a bolus given over 15 minutes to bring the patient out of shock as quickly as possible
{{PBI|HIV/AIDS}}
:::::* If the patient’s condition improves, give a crystalloid/colloid infusion of 10 ml/kg/hr for one hour. Then continue with crystalloid infusion and gradually reduce to 5–7 ml/kg/hr for 1–2 hours, then to 3–5 ml/kg/hr for 2–4 hours, and then to 2–3 ml/kg/hr or less, which can be maintained for up to 24–48 hours

:::::* If vital signs are still unstable (i.e. shock persists), review the haematocrit obtained before the first bolus. If the haematocrit was low (<40% in children and adult females, <45% in adult males), this indicates bleeding and the need to cross- match and transfuse blood as soon as possible (see treatment for haemorrhagic complications)
:* 1.1. '''Integrase strand transfer inhibitor-based regimens'''
:::::* If the haematocrit was high compared to the baseline value (if not available, use population baseline), change intravenous fluids to colloid solutions at 10–20 ml/kg as a second bolus over 30 minutes to one hour. After the second bolus, reassess the patient. If the condition improves, reduce the rate to 7–10 ml/kg/hr for 1–2 hours, then change back to crystalloid solution and reduce the rate of infusion as mentioned above. If the condition is still unstable, repeat the haematocrit after the second bolus
::* Preferred regimen (1): [[Dolutegravir]] 50 mg PO qd {{and}} [[Abacavir]] 600 mg-[[Lamivudine]] 300 mg PO qd in patients who are HLA-B*5701-negative
:::::* If the haematocrit decreases compared to the previous value (<40% in children and adult females, less than 45% in adult males), this indicates bleeding and the need to cross-match and transfuse blood as soon as possible (see treatment for haemorrhagic complications). If the haematocrit increases compared to the previous value or remains very high ( more than 50%), continue colloid solutions at 10–20 ml/kg as a third bolus over one hour. After this dose, reduce the rate to 7–10 ml/kg/hr for 1–2 hours, then change back to crystalloid solution and reduce the rate of infusion as mentioned above when the patient’s condition improves
::* Preferred regimen (2): [[Dolutegravir]] 50 mg PO qd {{and}} [[Tenofovir]] 300 mg-[[Emtricitabine]] 200 mg PO qd

::* Preferred regimen: [[Darunavir]] 800 mg-[[Ritonavir]] 100 mg PO qd {{and}} [[Tenofovir]] 300 mg-[[Emtricitabine]] 200 mg PO qd
:::::* Give 5–10ml/kg of fresh-packed red cells or 10–20 ml/kg of fresh whole blood at an appropriate rate and observe the clinical response. It is important that fresh whole blood or fresh red cells are given. Oxygen delivery at tissue level is optimal with high levels of 2,3 di-phosphoglycerate (2,3 DPG). Stored blood loses 2,3 DPG, low levels of which impede the oxygen-releasing capacity of haemoglobin, resulting in functional tissue hypoxia. A good clinical response includes improving haemodynamic status and acid-base balance
::* Alternative regimen (1): [[Atazanavir]] 300 mg-[[Cobicistat]] 150 mg PO qd {{and}} [[Tenofovir]] disoproxil fumarate 300 mg-[[Emtricitabine]] 200 mg PO qd only for patients with pre-treatment estimated CrCl ≥70 mL/min
:::::* Consider repeating the blood transfusion if there is further blood loss or no appropriate rise in haematocrit after blood transfusion. There is little evidence to support the practice of transfusing platelet concentrates and/or fresh-frozen plasma for severe bleeding. It is being practised when massive bleeding can not be managed with just fresh whole blood/fresh-packed cells, but it may exacerbate the fluid overload
::* Alternative regimen (2): [[Atazanavir]] 300 mg-[[Ritonavir]] 100 mg PO qd {{and}} [[Tenofovir]] 300 mg-[[Emtricitabine]] 200 mg PO qd
:::::* Great care should be taken when inserting a naso-gastric tube which may cause severe haemorrhage and may block the airway. A lubricated oro-gastric tube may minimize the trauma during insertion. Insertion of central venous catheters should be done with ultra-sound guidance or by a very experienced person
::* Alternative regimen (3): ([[Darunavir]] 800 mg-[[Cobicistat]] 150 mg PO qd {{or}} [[Darunavir]] 800 mg-[[Ritonavir]] 100 mg PO qd) {{and}} [[Abacavir]] 600 mg-[[Lamivudine]] 300 mg PO qd only for patients who are HLA-B*5701 negative

::::* Oxygen therapy should be given immediately
::* Alternative regimen (2): [[Rilpivirine]] 25 mg-[[Tenofovir]] 300 mg-[[Emtricitabine]] 200 mg PO qd
::::* When the following signs are present, intravenous fluids should be discontinued or reduced to the minimum rate necessary to maintain euglycaemia
:::::* signs of cessation of plasma leakage; stable blood pressure, pulse and peripheral perfusion; haematocrit decreases in the presence of a good pulse volume; afebrile for more than 24–48 days (without the use of antipyretics); resolving bowel/abdominal symptoms; improving urine output
::::* The management of fluid overload varies according to the phase of the disease and the patient’s haemodynamic status. If the patient has stable haemodynamic status and is out of the critical phase (more than 24–48 hours of defervescence), stop intravenous fluids but continue close monitoring. If necessary, give oral or intravenous furosemide 0.1–0.5 mg/kg/dose once or twice daily, or a continuous infusion of furosemide 0.1 mg/kg/hour. Monitor serum potassium and correct the ensuing hypokalaemia
::::* If the patient has stable haemodynamic status but is still within the critical phase, reduce the intravenous fluid accordingly. Avoid diuretics during the plasma leakage phase because they may lead to intravascular volume depletion
::::* Patients who remain in shock with low or normal haematocrit levels but show signs of fluid overload may have occult haemorrhage. Further infusion of large volumes of intravenous fluids will lead only to a poor outcome. Careful fresh whole blood transfusion should be initiated as soon as possible. If the patient remains in shock and the haematocrit is elevated, repeated small boluses of a colloid solution may help


:::* 5.2 '''Other complications of dengue'''
:* 1.4. '''Other regimen options'''
::::* Both hyperglycaemia and hypoglycaemia may occur, even in the absence of diabetes mellitus and/or hypoglycaemic agents. Electrolyte and acid-base imbalances are also common observations in severe dengue and are probably related to gastrointestinal losses through vomiting and diarrhoea or to the use of hypotonic solutions for resuscitation and correction of dehydration. Hyponatraemia, hypokalaemia, hyperkalaemia, serum calcium imbalances and metabolic acidosis (sodium bicarbonate for metabolic acidosis is not recommended for pH ≥ 7.15) can occur. One should also be alert for co-infections and nosocomial infections.

:::* 1.2 '''Provider-Administered''': Cryotherapy with liquid nitrogen or cryoprobe  {{or}} Surgical removal either by tangential scissor excision, tangential shave excision, curettage, laser,or electrosurgery {{or}} [[Trichloroacetic acid]] (TCA) {{or}} Bichloroacetic acid (BCA) 80%-90% solution
:::* Note (1): Many persons with external anal warts also have intra-anal warts. Thus, persons with external anal warts might benefit from an inspection of the anal canal by digital examination, standard anoscopy, or high-resolution anoscopy.
:::* Note (2): Might weaken condoms and vaginal diaphragms.
::* 2.'''Alternative Regimens for External Genital Warts'''
:::* 2.1 '''Urethral Meatus Warts'''
::::* Preferred regimen: Cryotherapy with liquid nitrogen {{or}} Surgical removal
:::* 2.2 '''Vaginal Warts'''
::::* Preferred regimen: Cryotherapy with liquid nitrogen {{or}} Surgical removal  {{or}}  (TCA {{or}} BCA 80%–90% solution)
::::* Note: The use of a cryoprobe in the vagina is not recommended because of the risk for vaginal perforation and fistula formation
:::* 2.3 '''Cervical Warts'''
::::* Preferred regimen: Cryotherapy with liquid nitrogen {{or}} Surgical removal {{or}} (TCA {{or}} BCA 80%–90% solution)
::::* Note: Management of cervical warts should include consultation with a specialist.For women who have exophytic cervical warts, a biopsy evaluation to exclude high-grade SIL must be performed before treatment is initiated.
:::* 2.4 '''Intra-anal Warts'''
::::* Preferred regimen: Cryotherapy with liquid nitrogen {{or}} Surgical removal {{or}} (TCA {{or}} BCA 80%–90% solution)
::::* Note: Management of intra-anal warts should include consultation with a specialist.
 
::* 3. '''Specific considerations'''
:::* 3.1 '''Follow-up'''
::::* Most anogenital warts respond within 3 months of therapy. Factors that might affect response to therapy include immunosuppression and treatment compliance. In general, warts located on moist surfaces or in intertriginous areas respond best to topical treatment. A new treatment modality should be selected when no substantial improvement is observed after a complete course of treatment or in the event of severe side effects; treatment response and therapy-associated side effects should be evaluated throughout the course of therapy.
 
:::* 3.2 '''Management of sex partners'''
::::* Persons should inform current partner(s) about having genital warts because the types of HPV that cause warts can be passed on to partners. Partners should receive counseling messages that partners might already have HPV despite no visible signs of warts, so HPV testing of sex partners of persons with genital warts is not recommended.
 
:::* 3.3 '''Pregnancy'''
::::* [[Podofilox]] (podophyllotoxin), [[Podophyllin]], and [[Sinecatechins]] should not be used during pregnancy. Imiquimod appears to pose low risk but should be avoided until more data are available.
::::* Cesarean delivery is indicated for women with anogenital warts if the pelvic outlet is obstructed or if vaginal delivery would result in excessive bleeding.
::::* Pregnant women with anogenital warts should be counseled concerning the low risk for warts on the larynx of their infants or children (recurrent respiratory papillomatosis).
 
:::* 3.4 '''HIV infection'''
::::* Data do not support altered approaches to treatment for persons with HIV infection.
::::* Squamous cell carcinomas arising in or resembling anogenital warts might occur more frequently among immunosuppressed persons, therefore requiring biopsy for confirmation of diagnosis for suspicious cases
 
:::* 3.5 '''High-grade squamous intraepithelial lesions'''
::::* Biopsy of an atypical wart might reveal HSIL or cancer of the anogenital tract. In this instance, referral to a specialist for treatment is recommended.

{{PBI|BK virus}}
:* '''Human polyomavirus (BK virus) treatment'''
::* '''Maintenance regimen consisting of triple immunosuppression therapy''': [[Calcineurin]] inhibitor ([[Cyclosporine]] or [[Tacrolimus]]) {{and}} an antimetabolite ([[Azathioprine]], [[Mycophenolate mofetil]], or [[Mycophenolate sodium]]), {{and}} [[Prednisone]] is to discontinue completely the antimetabolite (usually [[Mycophenolate]]) and decrease the dose of the [[Calcineurin]] inhibitor.
::* '''Alternative regimen (1)''': Decrease the [[Mycophenolate]] dose by 50 percent, followed by a 50 percent decrease in the [[Calcineurin]] inhibitor at three months if decoy cells persist. If using this approach, the target serum [[Tacrolimus]] trough level is 4 to 6, and the target serum [[Cyclosporine]] trough level is 60 to 100 ng/mL. [[Mycophenolate]] may be discontinued completely if viral activation persists. Maintenance immunosuppression then consists of [[Tacrolimus]] and low-dose [[Prednisone]].
::* '''Alternative regimen (2)''': Reduce both the [[Calcineurin]] inhibitor and the [[Mycophenolate]], which allows both the targeting of two pathways and lower total immunosuppression.
:::* Note (1): For those who are hypogammaglobulinemic, we administer intravenous immunoglobulins (IV IG) in replacement doses of 500 mg/kg. Quantitative immunoglobulins should be checked two to three months later to determine whether hypogammaglobulinemia has recurred. Intravenous immunoglobulins (IV IG) is also an option in certain settings, based upon polymerase chain reaction (PCR) and kidney biopsy results. IVIG may contain antibodies against BK and JC virus since these viruses are ubiquitous in the general population.
:::* Note (2): The goals of decreased immunosuppressive therapy are to restrain viral replication without triggering rejection.
:::* Note (3): Reduced immunosuppression (defined as lowering mean doses of [[Mycophenolate]] and [[Tacrolimus]]) resulted in the successful elimination of viremia (mean period of six months) and allograft survival.
:::* Note (4): Alternative approaches to reducing immunosuppression have also been effective
::::* 4.1 Changing from [[Tacrolimus]] to low-dose [[Cyclosporine]] not only reduces the effect of the [[Calcineurin]] inhibitor, but also reduces [[Mycophenolate]] concentrations.
::::* 4.2 Replacing the [[Calcineurin]] inhibitor with [[Sirolimus]], with or without discontinuation of the antimetabolite, has the advantage of avoiding the long-term [[Calcineurin]] inhibitor-related nephrotoxic effects.
::::* 4.3 Lowering the dose of [[Calcineurin]] inhibitors may slow the loss of renal function.
 
:* '''Primary Regimens'''
::* Decrease immunosuppression if possible. (Cornerstone of Treatment)
::* Suggested antiviral therapy is based on anecdotal data. If progressive renal dysfunction:
::* Fluoroquinolone {{and}} IVIG 500 mg/kg IV {{and}} Leflunomide 100 mg for daily for 3 days, then 10-20 mg PO daily
::* If refractory to all of the above, add [[Cidofovir]] 5 mg/kg once per week for 2 weeks, then once every other week  if refractory to all of the above
 
:* '''Ancillary Therapies in BK Virus Nephropathy'''
::* [[Cidofovir]] 0.25-1.0 mg/kg IV biweekly for 8 wk without [[Probenecid]], prehydration recommended
::* [[Leflunomide]] 100 mg loading dose for 3 days, 20-60 mg/day, goal [[Leflunomide]] trough 50-100 ng/mL (consider lower trough goals of 20-40 ng/mL given hemolysis risk)
::* IV Ig 1-2 g/kg IV for 1-2 doses or 150 mg/kg  IV biweekly for 8 wk

:::::::* Preferred regimen: [[Primaquine]] 0.25 mg/kg PO single dose with ACT
:::::* 6.22.2.1.2. '''Recurrent falciparum malaria'''
::::::* 6.22.2.1.2.1. '''Failure within 28 days '''
:::::::* Note: The recommended second-line treatment is an alternative ACT known to be effective in the region. Adherence to 7-day treatment regimens with [[Artesunate]] or [[Quinine]] both of which should be co-administered with [[Tetracycline]], or [[Doxycycline]] or [[Clindamycin]]) is likely to be poor if treatment is not directly observed; these regimens are no longer generally recommended.
::::::* 6.22.2.1.2.2. '''Failure after 28 days'''
:::::::* Note: All presumed treatment failures after 4 weeks of initial treatment should, from an operational standpoint, be considered new infections and be treated with the first-line ACT. However, reuse of [[Mefloquine]] within 60 days of first treatment is associated with an increased risk for neuropsychiatric reactions, and an alternative ACT should be used.
:::::* 6.22.2.1.3. '''Reducing the transmissibility of treated Plasmodium falciparum infections in low-transmission areas in  patients with Plasmodium falciparum malaria (except pregnant women, infants aged < 6 months and women breastfeeding infants aged < 6 months) '''
::::::* Note: Single dose of 0.25 mg/kg biweekly [[Primaquine]] with ACT
:::::* 6.22.2.1.4. '''Treating uncomplicated Plasmodium falciparum malaria in special risk groups'''
::::::* 6.22.2.1.4.1. '''Pregnancy '''
:::::::* First trimester of pregnancy : [[Quinine]] {{and}} [[Clindamycin]] 10 mg/kg/day PO bid for 7 days
:::::::* Second and third trimesters : [[Mefloquine]] is considered safe for the treatment of malaria during the second and third trimesters; however, it should be given only in combination with an artemisinin derivative.
:::::::* Note (1): [[Quinine]] is associated with an increased risk for hypoglycaemia in late pregnancy, and it should be used (with clindamycin) only if effective alternatives are not available.
:::::::* Note (2): [[Primaquine]] and [[Tetracyclines]] should not be used in pregnancy.
::::::* 6.22.2.1.4.2. '''Infants less than 5kg body weight'''
:::::::* Note: They should be treated with an ACT at the same mg/kg bw target dose as for children weighing 5 kg.
::::::* 6.22.2.1.4.4. '''Large and obese adults'''
:::::::* Note: For obese patients, less drug is often distributed to fat than to other tissues; therefore, they should be dosed on the basis of an estimate of lean body weight, ideal body weight. Patients who are heavy but not obese require the same mg/kg bw doses as lighter patients.
::::::* 6.22.2.1.4.5. '''Non-immune travellers'''
:::::::* Note: Treat travellers with uncomplicated P. falciparum malaria returning to nonendemic settings with an ACT.
::::::* 6.22.2.1.4.6. '''Uncomplicated hyperparasitaemia'''
:::::::* Note: People with P. falciparum hyperparasitaemia are at increased risk of treatment failure, severe malaria and death so should be closely monitored, in addition to receiving an ACT.
::::* 6.22.2.2. '''Treatment of uncomplicated malaria caused by Plasmodium vivax, Plasmodium ovale, Plasmodium malariae or Plasmodium knowlesi'''
:::::* 6.22.2.2.1.  '''Blood Stage infection'''
::::::* 6.22.2.2.1.1.  '''Uncomplicated malaria caused by Plasmodium vivax'''
:::::::* 6.22.2.2.1.1.1. '''In areas with chloroquine-sensitive Plasmodium vivax'''
::::::::* Preferred regimen: [[Chloroquine]] total dose of 25 mg/kg PO. [[Chloroquine]] is given at an initial dose of 10 mg/kg, followed by 10 mg/kg on the second day and 5 mg/kg on the third day PO
:::::::* 6.22.2.2.1.1.2. '''In areas with chloroquine-resistant Plasmodium vivax'''
::::::::* Note: ACTs containing [[Piperaquine]], [[Mefloquine]] {{or}} [[Lumefantrine]] are the recommended treatment, although [[Artesunate]] {{and}} [[Amodiaquine]] may also be effective in some areas. In the systematic review of ACTs for treating P. vivax malaria, [[Dihydroartemisinin]] {{and}} [[Piperaquine]] provided a longer prophylactic effect than ACTs with shorter half-lives ([[Artemether]] {{and}}[[Lumefantrine]]) {{or}} ([[Artesunate]] {{and}} [[Amodiaquine]]), with significantly fewer recurrent parasitaemias during 9 weeks of follow-up.
::::::* 6.22.2.2.1.2. '''Uncomplicated malaria caused by Plasmodium ovale, Plasmodium malariae or Plasmodium knowlesi malaria'''
:::::::* Note: Resistance of P. ovale, P. malariae and P. knowlesi to antimalarial drugs is not well characterized, and infections caused by these three species are generally considered to be sensitive to [[Chloroquine]]. In only one study, conducted in Indonesia, was resistance to [[Chloroquine]] reported in P. malariae. The blood stages of P. ovale, P. malariae and P. knowlesi should therefore be treated with the standard regimen of ACT or [[Chloroquine]], as for vivax malaria.
::::::* 6.22.2.2.1.3. '''Mixed malaria infections '''
:::::::* Note: ACTs are effective against all malaria species and so are the treatment of choice for mixed infections.
:::::* 6.22.2.2.2. '''Liver stages (hypnozoites) of Plasmodium vivax and Plasmodium ovale'''
::::::* Note: To prevent relapse, treat P. vivax or P. ovale malaria in children and adults (except pregnant women, infants aged < 6 months, women breastfeeding infants < 6 months, women breastfeeding older infants unless they are known not to be G6PD deficient and people with G6PD deficiency) with a 14-day course of [[Primaquine]] in all transmission settings. Strong recommendation, high-quality evidence In people with G6PD deficiency, consider preventing relapse by giving primaquine base at 0.75 mg base/kg bw once a week for 8 weeks, with close medical supervision for potential primaquine-induced adverse haematological effects.
:::::* 6.22.2.2.2.1. '''Primaquine for preventive relapse'''
::::::* Preferred regimen: [[Primaquine]] 0.25–0.5 mg/kg/day PO qd for 14 days
:::::* 6.22.2.2.2.2. '''Primaquine and glucose-6-phosphate dehydrogenase deficiency'''
::::::* Preferred regimen: [[Primaquine]] 0.75 mg base/kg/day PO once a week for 8 weeks
::::::* Note: The decision to give or withhold [[Primaquine]] should depend on the possibility of giving the treatment under close medical supervision, with ready access to health facilities with blood transfusion services.
:::::* 6.22.2.2.2.3. '''Prevention of relapse in pregnant or lacating women and infants'''
::::::* Note: [[Primaquine]] is contraindicated in pregnant women, infants < 6 months of age and in lactating women (unless the infant is known not to be G6PD deficient)
::::* 6.22.2.3. '''Treatment of severe malaria'''
:::::* 6.22.2.3.1. '''Treatment of severe falciparum infection with Artesunate'''
::::::* 6.22.2.3.1.1. '''Adults and children with severe malaria (including infants, pregnant women in all trimesters and lactating women)'''
:::::::* Preferred regimen: [[Artesunate]] IV/IM for at least 24 h and until they can tolerate oral medication. Once a patient has received at least 24 h of parenteral therapy and can tolerate oral therapy, complete treatment with 3 days of an ACT (add single dose [[Primaquine]] in areas of low transmission).
::::::* 6.22.2.3.1.2. '''Young children weighing < 20 kg'''
:::::::* Preferred regimen:[[Artesunate]] 3 mg/kg per dose IV/IM q24h
:::::::* Alternative regimen: use [[Artemether]] in preference to quinine for treating children and adults with severe malaria
:::::* 6.22.2.3.2.'''Treating cases of suspected severe malaria pending transfer to a higher-level facility (pre-referral treatment)'''
::::::* 6.22.2.3.2.1. '''Adults and children'''
:::::::* Preferred regimen: [[Artesunate]] IM q24h
:::::::* Alternative regimen: [[Artemether]] IM {{or}} [[Quinine]] IM
::::::* 6.22.2.3.2.2.  '''Children < 6 years'''
:::::::* Preferred regimen: Where intramuscular injections of artesunate are not available, treat with a single rectal dose (10 mg/kg) of [[Artesunate]], and refer immediately to an appropriate facility for further care.
:::::::* Note: Do not use rectal artesunate in older children and adults.
:::::* 6.22.2.3.3. '''Pregancy'''
::::::* Note: Parenteral artesunate is the treatment of choice in all trimesters. Treatment must not be delayed.
:::::* 6.22.2.3.4. '''Treatment of severe Plasmodium Vivax infection'''
::::::* Note: Parenteral [[Artesunate]], treatment can be completed with a full treatment course of oral ACT or [[Chloroquine]] (in countries where [[Chloroquine]] is the treatment of choice). A full course of radical treatment with [[Primaquine]] should be given after recovery.
:::::* 6.22.2.3.5. '''Additional aspects of management in severe malaria'''
::::::* Fluid therapy:  It is not possible to give general recommendations on fluid replacement; each patient must be assessed individually and fluid resuscitation based on the estimated deficit.
::::::* Blood Transfusion: In high-transmission settings, blood transfusion is generally recommended for children with a haemoglobin level of < 5 g/100 mL(haematocrit < 15%). In low-transmission settings, a threshold of 20% (haemoglobin,7 g/100 mL) is recommended.
::::::* Exchange blood transfusion: Exchange blood transfusion requires intensive nursing care and a relatively large volume of blood, and it carries significant risks. There is no consensus on the indications, benefits and dangers involved or on practical details such as the volume of blood that should be exchanged. It is, therefore, not possible to make any recommendation regarding the use of exchange blood transfusion.

  • 1.1 Follow-up
  • Patients should be re-examined 3–7 days after initiation of therapy. If treatment is successful, ulcers usually improve symptomatically within 3 days and objectively within 7 days after therapy. If no clinical improvement is evident, the clinician must consider whether 1) the diagnosis is correct, 2) the patient is coinfected with another STD, 3) the patient is infected with HIV, 4) the treatment was not used as instructed, or 5) the H. ducreyi strain causing the infection is resistant to the prescribed antimicrobial.
  • Clinical resolution of fluctuant lymphadenopathy is slower than that of ulcers and might require needle aspiration or incision and drainage, despite otherwise successful therapy. Although needle aspiration of buboes is a simpler procedure, incision and drainage might be preferred because of reduced need for subsequent drainage procedures.
  • 1.2 Management of sex partners

  • Preferred regimen (1): Lipid formulation of Amphotericin B (3.0–5.0 mg/kg IV q12h for 1–2 weeks) THEN Itraconazole (200 mg tid for 3 days THEN 200 mg bid for a total of 12 weeks).
  • Preferred regimen (2): Methylprednisolone (0.5–1.0 mg/kg IV q24h) during the first 1–2 weeks of antifungal therapy is recommended for patients who develop respiratory complications, including hypoxemia or significant respiratory distress
  • Alternative regimen: The deoxycholate formulation of Amphotericin B (0.7–1.0 mg/kg q24h IV) is an alternative to a lipid formulation in patients who are at a low risk for nephrotoxicity.
  • Note (1): In severe cases, cases accompanied by respiratory insufficiency, or hypoxemia, anecdotal reports suggest that corticosteroid therapy may hasten recovery
  • Note (2): The pulmonary infiltrates should be resolved on the chest radiograph before antifungal therapy is stopped.
  • 1.1.1.2 Mild to moderate:
  • Treatment is usually unnecessary
  • Preferred regimen for patients who continue to have symptoms for >1 month: Itraconazole (200 mg tid for 3 days {{then} 200 mg qd OR bid for 6–12 weeks)

  • 1.6.2 Immunosupressed patients
  • 1.6.3 Mild to moderate disease
  • Itraconazole (200 mg tid for 3 days and then bid qid for at least 12 months)
  • Note (1): Lifelong suppressive therapy with itraconazole (200 mg daily) may be required in immunosuppressed patients if immunosuppression cannot be reversed and in patients who relapse despite receipt of appropriate therapy
  • Note (2): Blood levels of itraconazole should be obtained to ensure adequate drug exposure
  • Note (3): Antigen levels should be measured during therapy and for 12 months after therapy is ended to monitor for relapse. Persistent low-level antigenuria may not be a reason to prolong treatment in patients who have completed appropriate therapy and have no evidence of active infection.
  • Note (4): Progressive disseminated histoplasmosis is fatal without therapy and treatment with either Amphotericin B or Itraconazole is highly effective. Among patients with AIDS and moderately severe to severe disseminated histoplasmosis, the rate of response was higher (88% vs. 64%) and the mortality rate was lower (2% vs. 13%) among recipients of liposomal amphotericin B (3 mg/kg qd for 1–2 weeks) than among recipients of the deoxycholate formulation.
  • 1.7 Prophylaxis recommended for immunosuppressed patients
  • Preferred regimen: Itraconazole (200 mg qd) in patients with HIV infection with CD4 cell counts <150 cells/mm3 in specific areas of endemicity where the incidence of histoplasmosis is >10 cases per 100 patient-years
  • Note: Prophylaxis with Itraconazole (200 mg qd) may be appropriate in specific circumstances in other immunosuppressed patients
  • 1.8 Performance Measures
  • Preferred regimen: Itraconazole is the preferred azole for initial therapy for patients with mild-to-moderate histoplasmosis and as step-down therapy after receipt of Amphotericin B
  • Note: When other azole agents are used, the medical record should document the specific reasons that Itraconazole was not used and why other azoles were used.
  • 14.1 Severe or moderately severe histoplasmosis
  • Preferred regimen: Amphotericin B
  • Note: When Amphotericin B is used the patient's electrolyte level renal function and blood cell count should be monitored several times per week and documented in the medical record.
  • Note (2): Itraconazole drug levels should be measured during the first month in patients with disseminated or chronic pulmonary histoplasmosis and these levels should be documented in the medical record as well as the physician's response to levels that are too low.
  • Note (3): Itraconazole should not be given to patients receiving contraindicated medications (i.e., pimozide, quinidine, dofetilide, lovastatin, simvastatin, midazolam, and triazolam). Reasons for deviation from this practice should be documented in the medical record.

  • 1.1 Treatment in pregnancy
  • The use of Iodoquinol in pregnancy is limited, and risk to the embryo-fetus is unknown, should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
  • Oral dose of Paromomycin generally is poorly absorbed from the gastrointestinal tract, with minimal, if any, systemic availability.
  • Metronidazole is in pregnancy category B. Data on the use of this drug in pregnant women are conflicting. The available evidence suggests use during pregnancy has a low risk of congenital anomalies. May be used during pregnancy in those patients who will clearly benefit from the drug, although its use in the first trimester is generally not advised.
  • 1.2 Treatment during lactation
  • Iodoquinol should be used with caution in breastfeeding women.
  • Oral dose of Paromomycin is unlikely to be excreted in breast milk, and the drug generally is poorly absorbed from the gastrointestinal tract.

  • 1. Cystoisospora belli treatment[281]
  • 1.1 Immunocompetent hosts
  • In the immunocompetent hosts, symptoms of Cystoisospora infection are usually self-limited.
  • Antimicrobial therapy to immunocompetent patients may be considered if symptoms do not start to resolve spontaneously after 5 to 7 days (depending upon severity)
  • Prefered regimen: Trimethoprim-sulfamethoxazole 160 mg/800 mg PO bid for 7-10 days

  • TMP-SMX should be avoided near-term because of the potential for hyperbilirubinemia and kernicterus in the newborn.
  • Ciprofloxacin should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
  • 1.1.2 During lactation
  • TMP-SMX generally should be avoided by women when nursing infants who are premature, jaundiced, ill, or stressed, or who have glucose-6-phosphate dehydrogenase deficiency.
  • The American Academy of Pediatrics classifies Ciprofloxacin as usually compatible with breastfeeding, whereas the World Health Organization recommends avoiding Ciprofloxacin while breastfeeding and CDC recommends Ciprofloxacin should be used during lactation only if the potential benefit justifies the potential risk to the fetus.
  • 1.1.3 In pediatric patients
  • The use of TMP-SMX in children less than 2 months of age generally is not recommended.

  • Preferred regimen (2): Trimethoprim-sulfamethoxazole 160 mg/800 mg PO/IV bid for 7-10 days
  • Note (1): One approach is to start with TMP-SMX (160 mg/800 mg) bid regimen first, and increase daily dose and/or duration (up to 3–4 weeks) if symptoms worsen or persist.
  • Note (2): IV therapy is recommended for patients with potential or documented malabsorption.
  • Alternative regimen (1): Pyrimethamine 50–75 mg PO qd AND Leucovorin 10–25 mg PO qd
  • Alternative regimen (2): Ciprofloxacin 500 mg PO bid for 7 days
  • 2. Cystoisospora belli prophylaxis[282]

  • Note (1): Criteria for discontinuation of chronic maintenance therapy: sustained increase in CD4 count > 200 cells/mm3 for > 6 months in response to ART and without evidence of active Cystoisospora belli infection
  • Note (2): Because of concerns about possible teratogenicity associated with first-trimester drug exposure, clinicians may withhold secondary prophylaxis during the first trimester and treat only symptomatic infection.

  • 2. Intestinal (diarrhea)[284]
  • Preferred regimen:
  • Adult: Albendazole 400 mg PO bid for 3 weeks for E. intestinalis.
  • Pediatric: Albendazole 15 mg/kg per day divided into 2 daily doses for 7 days for E. intestinalis.

Leishmania

  • Leishmaniasis
  • 1. Cutaneous Leishmaniasis[297]
  • Different Leishmania species cause Old World versus New World (American) cutaneous leishmaniasis. In the Old World (the Eastern Hemisphere), the etiologic agents include Leishmania tropica, L. major, and L. aethiopica, as well as L. infantum and L. donovani. The main species in the New World (the Western Hemisphere) are either in the L. mexicana species complex (L. mexicana, L. amazonensis, and L. venezuelensis) or the subgenus Viannia (L. [V.] braziliensis, L. [V.] guyanensis, L. [V.] panamensis, and L. [V.] peruviana). The Viannia subgenus is also referred to as the L. (V.) braziliensis species complex.

  • Preferred regimen (2): Artesunate 2–10 mg/kg/day PO qd AND Amodiaquine 7.5–15 mg/kg/day PO qd for 3 days
  • Note: A total therapeutic dose range of 6–30 mg/kg/day artesunate and 22.5–45 mg/kg/day per dose amodiaquine is recommended.
  • Dosage regimen based on Body weight (kg)
  • Body weight (kg)-4.5 to < 9- Artesunate 25 mg PO qd AND Amodiaquine 67.5 mg PO qd for 3 days
  • Body weight (kg)-9 to < 18 - Artesunate 50 mg PO qd AND Amodiaquine 135 mg PO qd for 3 days

  • 1.1.2 Reducing the transmissibility of treated P. falciparum infections In low-transmission areas in patients with P. falciparum malaria (except pregnant women, infants aged < 6 months and women breastfeeding infants aged < 6 months)
  • Preferred regimen: Single dose of 0.25 mg/kg Primaquine with ACT
  • 1.2 Recurrent Falciparum Malaria
  • 1.2.1 Failure within 28 days
  • Note:The recommended second-line treatment is an alternative ACT known to be effective in the region. Adherence to 7-day treatment regimens (with artesunate or quinine both of which should be co-administered with + tetracycline, or doxycycline or clindamycin) is likely to be poor if treatment is not directly observed; these regimens are no longer generally recommended.
  • 1.2.2 Failure after 28 days
  • Note: all presumed treatment failures after 4 weeks of initial treatment should, from an operational standpoint, be considered new infections and be treated with the first-line ACT. However, reuse of mefloquine within 60 days of first treatment is associated with an increased risk for neuropsychiatric reactions, and an alternative ACT should be used.
  • 1.3 Reducing the transmissibility of treated P. falciparum infections In low-transmission areas in patients with P. falciparum malaria (except pregnant women, infants aged < 6 months and women breastfeeding infants aged < 6 months)
  • Note: Single dose of 0.25 mg/kg bw Primaquine with ACT
  • 1.4 Treating uncomplicated P. falciparum malaria in special risk groups
  • 1.4.1 Pregnancy
  • First trimester of pregnancy : Quinine AND Clindamycin 10mg/kg/day PO bid for 7 days
  • Second and third trimesters : Mefloquine is considered safe for the treatment of malaria during the second and third trimesters; however, it should be given only in combination with an artemisinin derivative.
  • Note (1): Quinine is associated with an increased risk for hypoglycaemia in late pregnancy, and it should be used (with clindamycin) only if effective alternatives are not available.
  • Note (2): Primaquine and tetracyclines should not be used in pregnancy.
  • 1.4.2 Infants less than 5kg body weight : with an ACT at the same mg/kg bw target dose as for children weighing 5 kg.
  • 1.4.3 Patients co-infected with HIV: should avoid Artesunate + SP if they are also receiving Co-trimoxazole, and avoid Artesunate AND Amodiaquine if they are also receiving efavirenz or zidovudine.
  • 1.4.4 Large and Obese adults: For obese patients, less drug is often distributed to fat than to other tissues; therefore, they should be dosed on the basis of an estimate of lean body weight, ideal body weight. Patients who are heavy but not obese require the same mg/kg bw doses as lighter patients.
  • 1.4.5 Patients co-infected with TB: Rifamycins, in particular rifampicin, are potent CYP3A4 inducers with weak antimalarial activity. Concomitant administration of rifampicin during quinine treatment of adults with malaria was associated with a significant decrease in exposure to quinine and a five-fold higher recrudescence rate
  • 1.4.6 Non-immune travellers : Treat travellers with uncomplicated P. falciparum malaria returning to nonendemic settings with an ACT.
  • 1.4.7 Uncomplicated hyperparasitaemia: People with P. falciparum hyperparasitaemia are at increased risk of treatment failure, severe malaria and death so should be closely monitored, in addition to receiving an ACT.
  • 2. Treatment of uncomplicated malaria caused by P. vivax, P. ovale, P. malariae or P. knowlesi
  • 2.1 Blood Stage infection
  • 2.1.1. Uncomplicated malaria caused by P. vivax
  • 2.1.1.1 In areas with chloroquine-sensitive P. vivax
  • Preferred regimen: Chloroquine total dose of 25 mg/kg PO. Chloroquine is given at an initial dose of 10 mg/kg, followed by 10 mg/kg on the second day and 5 mg/kg on the third day.
  • 2.1.1.2 In areas with chloroquine-resistant P. vivax
  • 2.1.2 Uncomplicated malaria caused by P. ovale, P. malariae or P. knowlesi malaria
  • Note: Resistance of P. ovale, P. malariae and P. knowlesi to antimalarial drugs is not well characterized, and infections caused by these three species are generally considered to be sensitive to chloroquine. In only one study, conducted in Indonesia, was resistance to chloroquine reported in P. malariae. The blood stages of P. ovale, P. malariae and P. knowlesi should therefore be treated with the standard regimen of ACT or Chloroquine, as for vivax malaria.
  • 2.1.3 Mixed malaria infections
  • Note: ACTs are effective against all malaria species and so are the treatment of choice for mixed infections.
  • 2.2 Liver stages (hypnozoites) of P. vivax and P. ovale
  • Note: To prevent relapse, treat P. vivax or P. ovale malaria in children and adults (except pregnant women, infants aged < 6 months, women breastfeeding infants < 6 months, women breastfeeding older infants unless they are known not to be G6PD deficient and people with G6PD deficiency) with a 14-day course of primaquine in all transmission settings. Strong recommendation, high-quality evidence In people with G6PD deficiency, consider preventing relapse by giving primaquine base at 0.75 mg base/kg bw once a week for 8 weeks, with close medical supervision for potential primaquine-induced adverse haematological effects.]
  • 2.2.1 Primaquine for preventive relapse
  • Preferred regimen: Primaquine 0.25–0.5 mg/kg/day PO qd for 14 days
  • 2.2.2 Primaquine and glucose-6-phosphate dehydrogenase deficiency
  • Preferred regimen: Primaquine 0.75 mg base/kg/day PO once a week for 8 weeks.

  • 3.1.2 Young children weighing < 20 kg
  • Preferred regimen:Artesunate 3 mg/kg per dose IV/IM q24h
  • Alternatives regimen: use Artemether in preference to quinine for treating children and adults with severe malaria

  • Note: Do not use rectal artesunate in older children and adults.
  • 3.3 Pregancy
  • Note: Parenteral artesunate is the treatment of choice in all trimesters. Treatment must not be delayed.
  • 3.4 Treatment of severe P. Vivax infection
  • Note: parenteral artesunate, treatment can be completed with a full treatment course of oral ACT or chloroquine (in countries where chloroquine is the treatment of choice). A full course of radical treatment with primaquine should be given after recovery.
  • 3.5 Additional aspects of management in severe malaria
  • Fluid therapy: It is not possible to give general recommendations on fluid replacement; each patient must be assessed individually and fluid resuscitation based on the estimated deficit.
  • Blood Transfusion :In high-transmission settings, blood transfusion is generally recommended for children with a haemoglobin level of < 5 g/100 mL(haematocrit < 15%). In low-transmission settings, a threshold of 20% (haemoglobin,7 g/100 mL) is recommended.
  • Exchange blood transfusion: Exchange blood transfusion requires intensive nursing care and a relatively large volume of blood, and it carries significant risks. There is no consensus on the indications, benefits and dangers involved or on practical details such as the volume of blood that should be exchanged. It is, therefore, not possible to make any recommendation regarding the use of exchange blood transfusion.

  • 1. Patients who may be sent home
  • These are patients who are able to tolerate adequate volumes of oral fluids and pass urine at least once every six hours, and do not have any of the warning signs, particularly when fever subsides
  • Patients who are sent home should be monitored daily by health care providers for temperature pattern, volume of fluid intake and losses, urine output (volume and frequency), warning signs, signs of plasma leakage and bleeding, haematocrit, and white blood cell and platelet counts
  • 2. Ambulatory patients with stable haematocrit can be sent home
  • Encourage oral intake of oral rehydration solution (ORS), fruit juice and other fluids containing electrolytes and sugar to replace losses from fever and vomiting
  • Give Paracetamol for high fever if the patient is uncomfortable. The interval of paracetamol dosing should not be less than six hours. Tepid sponge if the patient still has high fever
  • Should be brought to hospital immediately if any of the following occur: no clinical improvement, deterioration around the time of defervescence, severe abdominal pain, persistent vomiting, cold and clammy extremities, lethargy or irritability/restlessness, bleeding (e.g. black stools or coffee-ground vomiting), not passing urine for more than 4–6 hours
  • 3. Patients who should be referred for in-hospital management
  • Patients may need to be admitted to a secondary health care centre for close observation, particularly as they approach the critical phase. These include patients with warning signs (Abdominal pain or tenderness, Persistent vomiting, Clinical fluid accumulation, Mucosal bleed, Lethargy, restlessness, Liver enlargment >2cm, Laboratory:increase in HCT concurrent with rapid decrease in platelet count), those with co-existing conditions that may make dengue or its management more complicated (such as pregnancy, infancy, old age, obesity, diabetes mellitus, renal failure, chronic haemolytic diseases), and those with certain social circumstances (such as living alone, or living far from a health facility without reliable means of transport)
  • 3.1 With warning signs
  • Obtain a reference haematocrit before fluid therapy. Give only isotonic solutions such as 0.9% saline, Ringer’s lactate, or Hartmann’s solution. Start with 5–7 ml/ kg/hour for 1–2 hours, then reduce to 3–5 ml/kg/hr for 2–4 hours, and then reduce to 2–3 ml/kg/hr or less according to the clinical response
  • Reassess the clinical status and repeat the haematocrit. If the haematocrit remains the same or rises only minimally, continue with the same rate (2–3 ml/kg/hr) for another 2–4 hours. If the vital signs are worsening and haematocrit is rising rapidly, increase the rate to 5–10 ml/kg/hour for 1–2 hours. Reassess the clinical status, repeat the haematocrit and review fluid infusion rates accordingly
  • Give the minimum intravenous fluid volume required to maintain good perfusion and urine output of about 0.5 ml/kg/hr. Intravenous fluids are usually needed for only 24–48 hours. Reduce intravenous fluids gradually when the rate of plasma leakage decreases towards the end of the critical phase. This is indicated by urine output and/or oral fluid intake that is/are adequate, or haematocrit decreasing below the baseline value in a stable patient
  • Patients with warning signs should be monitored by health care providers until the period of risk is over. A detailed fluid balance should be maintained. Parameters that should be monitored include vital signs and peripheral perfusion (1–4 hourly until the patient is out of the critical phase), urine output (4–6 hourly), haematocrit (before and after fluid replacement, then 6–12 hourly), blood glucose, and other organ functions (such as renal profile, liver profile, coagulation profile, as indicated)
  • 3.2 Without warning signs
  • Encourage oral fluids. If not tolerated, start intravenous fluid therapy of 0.9% saline or Ringer’s lactate with or without dextrose at maintenance rate. For obese and overweight patients, use the ideal body weight for calculation of fluid infusion. Patients may be able to take oral fluids after a few hours of intravenous fluid therapy. Thus, it is necessary to revise the fluid infusion frequently. Give the minimum volume required to maintain good perfusion and urine output. Intravenous fluids are usually needed only for 24–48 hours
  • Patients should be monitored by health care providers for temperature pattern, volume of fluid intake and losses, urine output (volume and frequency), warning signs, haematocrit, and white blood cell and platelet counts. Other laboratory tests (such as liver and renal functions tests) can be done, depending on the clinical picture and the facilities of the hospital or health centre
  • 4. Severe dengue
  • Severe dengue: Severe plasma leakage leading to dengue shock and/or fluid accumulation with respiratory distress; severe haemorrhages; severe organ impairment (hepatic damage, renal impairment, cardiomyopathy, encephalopathy or encephalitis)
  • 4.1 Treatment of shock
  • 4.1.1 Compensated shock
  • Start intravenous fluid resuscitation with isotonic crystalloid solutions at 5–10 ml/kg/hour over one hour. Then reassess the patient’s condition (vital signs, capillary refill time, haematocrit, urine output). The next steps depend on the situation
  • If the patient’s condition improves, intravenous fluids should be gradually reduced to 5–7 ml/kg/hr for 1–2 hours, then to 3–5 ml/kg/hr for 2–4 hours, then to 2–3 ml/kg/hr, and then further depending on haemodynamic status, which can be maintained for up to 24–48 hours
  • If vital signs are still unstable (i.e. shock persists), check the haematocrit after the first bolus. If the haematocrit increases or is still high (>50%), repeat a second bolus of crystalloid solution at 10–20 ml/kg/hr for one hour. After this second bolus, if there is improvement, reduce the rate to 7–10 ml/ kg/hr for 1–2 hours, and then continue to reduce as above. If haematocrit decreases compared to the initial reference haematocrit (<40% in children and adult females, <45% in adult males), this indicates bleeding and the need to cross-match and transfuse blood as soon as possible
  • Further boluses of crystalloid or colloidal solutions may need to be given during the next 24–48 hours
  • 4.1.2 Hypotensive shock
  • Initiate intravenous fluid resuscitation with crystalloid or colloid solution (if available) at 20 ml/kg as a bolus given over 15 minutes to bring the patient out of shock as quickly as possible
  • If the patient’s condition improves, give a crystalloid/colloid infusion of 10 ml/kg/hr for one hour. Then continue with crystalloid infusion and gradually reduce to 5–7 ml/kg/hr for 1–2 hours, then to 3–5 ml/kg/hr for 2–4 hours, and then to 2–3 ml/kg/hr or less, which can be maintained for up to 24–48 hours
  • If vital signs are still unstable (i.e. shock persists), review the haematocrit obtained before the first bolus. If the haematocrit was low (<40% in children and adult females, <45% in adult males), this indicates bleeding and the need to cross- match and transfuse blood as soon as possible (see treatment for haemorrhagic complications)
  • If the haematocrit was high compared to the baseline value (if not available, use population baseline), change intravenous fluids to colloid solutions at 10–20 ml/kg as a second bolus over 30 minutes to one hour. After the second bolus, reassess the patient. If the condition improves, reduce the rate to 7–10 ml/kg/hr for 1–2 hours, then change back to crystalloid solution and reduce the rate of infusion as mentioned above. If the condition is still unstable, repeat the haematocrit after the second bolus
  • If the haematocrit decreases compared to the previous value (<40% in children and adult females, less than 45% in adult males), this indicates bleeding and the need to cross-match and transfuse blood as soon as possible (see treatment for haemorrhagic complications). If the haematocrit increases compared to the previous value or remains very high ( more than 50%), continue colloid solutions at 10–20 ml/kg as a third bolus over one hour. After this dose, reduce the rate to 7–10 ml/kg/hr for 1–2 hours, then change back to crystalloid solution and reduce the rate of infusion as mentioned above when the patient’s condition improves
  • Further boluses of fluids may need to be given during the next 24 hours. The rate and volume of each bolus infusion should be titrated to the clinical response. Patients with severe dengue should be admitted to the high-dependency or intensive care area
  • 4.2 Treatment of haemorrhagic complications
  • Blood transfusion required
  • Give 5–10ml/kg of fresh-packed red cells or 10–20 ml/kg of fresh whole blood at an appropriate rate and observe the clinical response. It is important that fresh whole blood or fresh red cells are given. Oxygen delivery at tissue level is optimal with high levels of 2,3 di-phosphoglycerate (2,3 DPG). Stored blood loses 2,3 DPG, low levels of which impede the oxygen-releasing capacity of haemoglobin, resulting in functional tissue hypoxia. A good clinical response includes improving haemodynamic status and acid-base balance
  • Consider repeating the blood transfusion if there is further blood loss or no appropriate rise in haematocrit after blood transfusion. There is little evidence to support the practice of transfusing platelet concentrates and/or fresh-frozen plasma for severe bleeding. It is being practised when massive bleeding can not be managed with just fresh whole blood/fresh-packed cells, but it may exacerbate the fluid overload
  • Great care should be taken when inserting a naso-gastric tube which may cause severe haemorrhage and may block the airway. A lubricated oro-gastric tube may minimize the trauma during insertion. Insertion of central venous catheters should be done with ultra-sound guidance or by a very experienced person
  • 5. Treatment of complications and other areas of treatment
  • 5.1 Fluid overload
  • Oxygen therapy should be given immediately
  • When the following signs are present, intravenous fluids should be discontinued or reduced to the minimum rate necessary to maintain euglycaemia
  • signs of cessation of plasma leakage; stable blood pressure, pulse and peripheral perfusion; haematocrit decreases in the presence of a good pulse volume; afebrile for more than 24–48 days (without the use of antipyretics); resolving bowel/abdominal symptoms; improving urine output
  • The management of fluid overload varies according to the phase of the disease and the patient’s haemodynamic status. If the patient has stable haemodynamic status and is out of the critical phase (more than 24–48 hours of defervescence), stop intravenous fluids but continue close monitoring. If necessary, give oral or intravenous furosemide 0.1–0.5 mg/kg/dose once or twice daily, or a continuous infusion of furosemide 0.1 mg/kg/hour. Monitor serum potassium and correct the ensuing hypokalaemia
  • If the patient has stable haemodynamic status but is still within the critical phase, reduce the intravenous fluid accordingly. Avoid diuretics during the plasma leakage phase because they may lead to intravascular volume depletion
  • Patients who remain in shock with low or normal haematocrit levels but show signs of fluid overload may have occult haemorrhage. Further infusion of large volumes of intravenous fluids will lead only to a poor outcome. Careful fresh whole blood transfusion should be initiated as soon as possible. If the patient remains in shock and the haematocrit is elevated, repeated small boluses of a colloid solution may help
  • 5.2 Other complications of dengue
  • Both hyperglycaemia and hypoglycaemia may occur, even in the absence of diabetes mellitus and/or hypoglycaemic agents. Electrolyte and acid-base imbalances are also common observations in severe dengue and are probably related to gastrointestinal losses through vomiting and diarrhoea or to the use of hypotonic solutions for resuscitation and correction of dehydration. Hyponatraemia, hypokalaemia, hyperkalaemia, serum calcium imbalances and metabolic acidosis (sodium bicarbonate for metabolic acidosis is not recommended for pH ≥ 7.15) can occur. One should also be alert for co-infections and nosocomial infections.
  • 5.3 Supportive care and adjuvant therapy
  • renal replacement therapy, with a preference to continuous veno-venous haemodialysis (CWH), since peritoneal dialysis has a risk of bleeding;
  • vasopressor and inotropic therapies as temporary measures to prevent life- threatening hypotension in dengue shock and during induction for intubation, while correction of intravascular volume is being vigorously carried out;
  • further treatment of organ impairment, such as severe hepatic involvement or encephalopathy or encephalitis;
  • further treatment of cardiac abnormalities, such as conduction abnormalities, may occur (the latter usually not requiring interventions)
  • West nile virus
  • 1.1. Prevention
  • No WNV vaccines are licensed for use in humans. In the absence of a vaccine, prevention of WNV disease depends on community-level mosquito control programs to reduce vector densities, personal protective measures to decrease exposure to infected mosquitoes, and screening of blood and organ donors.
  • Personal protective measures include use of mosquito repellents, wearing long-sleeved shirts and long pants, and limiting outdoor exposure from dusk to dawn. Using air conditioning, installing window and door screens, and reducing peridomestic mosquito breeding sites, can further decrease the risk for WNV exposure.
  • Blood and some organ donations in the United States are screened for WNV infection; health care professionals should remain vigilant for the possible transmission of WNV through blood transfusion or organ transplantation. Any suspected WNV infections temporally associated with blood transfusion or organ transplantation should be reported promptly to the appropriate state health department.
  • 1.2. Treatment
  • There is no specific treatment for WNV disease; clinical management is supportive. Patients with severe meningeal symptoms often require pain control for headaches and antiemetic therapy and rehydration for associated nausea and vomiting. Patients with encephalitis require close monitoring for the development of elevated intracranial pressure and seizures. Patients with encephalitis or poliomyelitis should be monitored for inability to protect their airway. Acute neuromuscular respiratory failure may develop rapidly and prolonged ventilatory support may be required.
  • Preferred regimen: No specific treatment is available for yellow fever. In the toxic phase, supportive treatment includes therapies for treating dehydration and fever. Ribavirin has failed in several studies in the monkey model.
  • Note: An international seminar held by WHO in 1984 recommended maintenance of nutrition, prevention of hypoglycemia, maintenance of the blood pressure with fluids and vasoactive drugs, prevention of bleeding with fresh-frozen plasma, dialysis if renal failure, correction of metabolic acidosis, administration of cimetidine IV to avoid gastric bleeding and oxygen if needed.
Chikungunya Fever [389]
  • Preferred regimen: no specific therapeutics agents are available and there are no licensed vaccines to prevent Chikungunya Fever.
  • Note: Anti inflammatory drugs can be used to control joint swelling and arthritis.
  • Preferred regimen: No therapy recommended. If within 2 wks of exposure, IVIG 0.02 mL per kg IM times 1 protective.

  • 4 Prevention of varicella zoster virus (VZV) Infections in HIV-Infected Adults and Adolescents
  • 4.1 Pre-Exposure Prevention of VZV Primary Infection
  • Indications
  • Adult and adolescent patients with CD4 count ≥200 cells/mm3 without documentation of vaccination, health-care provider diagnosis or verification of a history of varicella or herpes zoster, laboratory confirmation of disease, or persons who are seronegative for VZV. Routine VZV serologic testing in HIV-infected adults and adolescents is not recommended.
  • Vaccination
  • Primary varicella vaccination (Varivax™), 2 doses (0.5 mL SQ) administered 3 months apart
  • If vaccination results in disease because of vaccine virus, treatment with acyclovir is recommended.
  • VZV-susceptible household contacts of susceptible HIV-infected persons should be vaccinated to prevent potential transmission of VZV to their HIV-infected contacts.
  • If post-exposure VariZIG has been administered, wait at least 5 months before varicella vaccination.
  • If post-exposure acyclovir has been administered, wait at least 3 days before varicella vaccine.
  • 4.2 Post-Exposure Prophylaxis
  • Indication
  • Close contact with a person who has active varicella or herpes zoster, and
  • Is susceptible to VZV (i.e., has no history of vaccination or of either condition, or is known to be VZV seronegative)
  • Preferred regimen: VariZIG 125 IU /10 kg (maximum of 625 IU) IM, administered as soon as possible and within 10 days after exposure to a person with active varicella or herpes zoster
  • Alternative regimen (Begin 7–10 Days After Exposure): Acyclovir 800 mg PO 5 times/day for 5–7 days OR Valacyclovir 1 g PO tid for 5–7 days
  • If post-exposure VariZIG has been administered, wait at least 5 months before varicella vaccination.
  • Note: Patients receiving monthly high dose IVIG (i.e., >400 mg/kg) are likely to be protected against VZV and probably do not require VariZIG if the last dose of IVIG was administered <3 weeks before VZV exposure.
  • Note: Neither these pre-emptive interventions nor post-exposure varicella vaccination have been studied in HIV-infected adults and adolescents.
  • If acyclovir or valacyclovir is used, varicella vaccines should not be given until at least 72 hours after the last dose of the antiviral drug.

  • 2.4 Intra-anal Warts
  • Preferred regimen: Cryotherapy with liquid nitrogen OR Surgical removal OR (TCA OR BCA 80%–90% solution)
  • Note: Management of intra-anal warts should include consultation with a specialist.
  • 3. Specific considerations
  • 3.1 Follow-up
  • Most anogenital warts respond within 3 months of therapy. Factors that might affect response to therapy include immunosuppression and treatment compliance. In general, warts located on moist surfaces or in intertriginous areas respond best to topical treatment. A new treatment modality should be selected when no substantial improvement is observed after a complete course of treatment or in the event of severe side effects; treatment response and therapy-associated side effects should be evaluated throughout the course of therapy.
  • 3.2 Management of sex partners
  • Persons should inform current partner(s) about having genital warts because the types of HPV that cause warts can be passed on to partners. Partners should receive counseling messages that partners might already have HPV despite no visible signs of warts, so HPV testing of sex partners of persons with genital warts is not recommended.
  • 3.3 Pregnancy
  • Podofilox (podophyllotoxin), Podophyllin, and Sinecatechins should not be used during pregnancy. Imiquimod appears to pose low risk but should be avoided until more data are available.
  • Cesarean delivery is indicated for women with anogenital warts if the pelvic outlet is obstructed or if vaginal delivery would result in excessive bleeding.
  • Pregnant women with anogenital warts should be counseled concerning the low risk for warts on the larynx of their infants or children (recurrent respiratory papillomatosis).
  • 3.4 HIV infection
  • Data do not support altered approaches to treatment for persons with HIV infection.
  • Squamous cell carcinomas arising in or resembling anogenital warts might occur more frequently among immunosuppressed persons, therefore requiring biopsy for confirmation of diagnosis for suspicious cases
  • 3.5 High-grade squamous intraepithelial lesions
  • Biopsy of an atypical wart might reveal HSIL or cancer of the anogenital tract. In this instance, referral to a specialist for treatment is recommended.

  • Note:Patients with severe disease may have diarrhea and may not absorb oseltamivir efficiently
  • 2. Patients with Avian Influenza who have diarrhea and malabsorption
  • Preferred regimen (1): Zanamivir 10 mg inhaled bid for minimum 5 days
  • Preferred regimen (2): Peramivir 600 mg IV as a single dose for 1 day
  • Note(1): Preliminary evidence demonstrates that Neuraminidase inhibitor can reduce the duration of viral replication and improve survival among patients with avian influenza. In cases of suspected avian influenza, one of the following 3 neuraminidase inhibitors should be administered as soon possible, preferably within 48 hours of symptom onset.
  • Note(2): The use of Corticosteroids is not recommended.
  • Note(3): Physicians may consider increasing either the recommended daily dose and/or the duration of treatment in cases of severe disease.
  • Note(4): The use of Amantadine is not recommended as most H5N1 and H7N9 avian influenza viruses are resistant to it.[412]
  • Note(5): Supportive care is also an important cornerstone of the care of patients with avian influenza. Considering the severity of the illness and the possible complications, patients may require fluid resuscitation, vasopressors, intubation and ventilation, paracentesis, hemodialysis or hemofiltration, and parentral nutrition.

  • 1. Condition1: Patients who have severe or progressive clinical illness
  • Preferred regimen: Oseltamivir 150 mg PO bid
  • Note (1): Treatment duration depends on clinical response
  • Note (2): Where the clinical course remains severe or progressive, despite 5 or more days of antiviral treatment, monitoring of virus replication and shedding, and antiviral drug susceptibility testing is desirable
  • Note (3): Antiviral treatment should be maintained without a break until virus infection is resolved or there is satisfactory clinical improvement
  • Note (4): Patients who have severe or progressive clinical illness, but who are unable to take oral medication may be treated with oseltamivir administered by nasogastric or orogastric tube
  • 2. Condition2: In situations where oseltamivir is not available, or not possible to use, patients who have severe or progressive clinical illness
  • Preferred regimen: Zanamivir inhaled
  • Note: Zanamivir IV should be considered where available and is recommended for those with serious or progressive illness. If not available, Peramivir IV may be considered
  • 3. Condition3: Severely immunosuppressed patients

  • Measles
  • 1.1. Prevention
  • 1.1.1. Vaccines
  • Note (1): Measles can be prevented with measles-containing vaccine, which is primarily administered as the combination measles-mumps-rubella (MMR) vaccine. The combination measles-mumps-rubella-varicella (MMRV) vaccine can be used for children aged 12 months through 12 years for protection against measles, mumps, rubella and varicella. Single-antigen measles vaccine is not available.
  • Note (2): Vaccination recommendations
  • Children: CDC recommends routine childhood immunization for MMR vaccine starting with the first dose at 12 through 15 months of age, and the second dose at 4 through 6 years of age or at least 28 days following the first dose.
  • Students at post-high school educational institutions: Students at post-high school educational institutions without evidence of measles immunity need two doses of MMR vaccine, with the second dose administered no earlier than 28 days after the first dose.
  • Adults: People who are born during or after 1957 who do not have evidence of immunity against measles should get at least one dose of MMR vaccine.
  • International travelers: People 6 months of age or older who will be traveling internationally should be protected against measles. Before travelling internationally,
  • Infants 6 through 11 months of age should receive one dose of MMR vaccine
  • Children 12 months of age or older should have documentation of two doses of MMR vaccine (the first dose of MMR vaccine should be administered at age 12 months or older; the second dose no earlier than 28 days after the first dose)
  • Teenagers and adults born during or after 1957 without evidence of immunity against measles should have documentation of two doses of MMR vaccine, with the second dose administered no earlier than 28 days after the first dose
  • 1.1.2. Post-exposure Prophylaxis
  • 1.1.2.1. Indication
  • People exposed to measles who cannot readily show that they have evidence of immunity against measles should be offered post-exposure prophylaxis (PEP) or be excluded from the setting (school, hospital, childcare). MMR vaccine, if administered within 72 hours of initial measles exposure, or immunoglobulin (IG), if administered within six days of exposure, may provide some protection or modify the clinical course of disease.
  • Note (1): If MMR vaccine is not administered within 72 hours of exposure as PEP, MMR vaccine should still be offered at any interval following exposure to the disease in order to offer protection from future exposures. People who receive MMR vaccine or IG as PEP should be monitored for signs and symptoms consistent with measles for at least one incubation period.
  • Note (2): If many measles cases are occurring among infants younger than 12 months of age, measles vaccination of infants as young as 6 months of age may be used as an outbreak control measure. Note that children vaccinated before their first birthday should be revaccinated when they are 12 through 15 months old and again when they are 4 through 6 years of age.
  • Note (3): People who are at risk for severe illness and complications from measles, such as infants younger than 12 months of age, pregnant women without evidence of measles immunity, and people with severely compromised immune systems, should receive IG. Intramuscular IG (IGIM) should be given to all infants younger than 12 months of age who have been exposed to measles.
  • Note (4): For infants aged 6 through 11 months, MMR vaccine can be given in place of IG, if administered within 72 hours of exposure. Because pregnant women might be at higher risk for severe measles and complications, intravenous IG (IGIV) should be administered to pregnant women without evidence of measles immunity who have been exposed to measles. People with severely compromised immune systems who are exposed to measles should receive IGIV regardless of immunologic or vaccination status because they might not be protected by MMR vaccine.
  • Preferred regimen: The recommended dose of IGIM is 0.5 mL/kg of body weight (maximum dose = 15 mL) and the recommended dose of IGIV is 400 mg/kg.
  • Note (5): If a healthcare provider without evidence of immunity is exposed to measles, MMR vaccine should be given within 72 hours, or IG should be given within 6 days when available. Exclude healthcare personnel without evidence of immunity from duty from day 5 after first exposure to day 21 after last exposure, regardless of post-exposure vaccine.
  • 1.2. Treatment
  • Note (1): There is no specific antiviral therapy for measles. Medical care is supportive and to help relieve symptoms and address complications such as bacterial infections.
  • Note (2): Severe measles cases among children, such as those who are hospitalized, should be treated with vitamin A. Vitamin A should be administered immediately on diagnosis and repeated the next day. The recommended age-specific daily doses are
  • 50,000 IU for infants younger than 6 months of age
  • 100,000 IU for infants 6–11 months of age
  • 200,000 IU for children 12 months of age and older


  • Middle East Respiratory Syndrome treatment
  • Preferred regimen: supportive care. There is no antiviral recommended for this infection at this moment, even though experimental therapies are at research (IFNs, Ribavirin, Lopinavir, Mycophenolic acid, Cyclosporine, Chloroquine, Chlorpromazine, Loperamide, 6-mercaptopurine and 6-thioguanine). Supportive care include: administer oxygen to patients with severe acute pulmonary infection with signs of respiratory distress, hypoxaemia or shock; use conservative fluids management, avoid administering high-dose systemic glucocorticoids, use non-invasive ventilation, but, if its nor effective, do not delay endotracheal intubation; use lung-protective strategy for intubated patients, recognize sepsis as early as possible and treat it accordingly.[414]

  • 1.1 In case of adverse events
  • Preferred regimen: Decrease dose or discontinue Ribavirin
  • 1.2 Creatinine clearance
  • 30–50 mL/min: Ribavirin PO/IV maximal 200 mg q8h
  • 10–30 mL/ min: No recommendation can be given


  • 1. Erythema infectiosum
  • Supportive therapy: Symptomatic treatment only
  • 2. Arthritis/arthalgia

  • 4. Fetal hydrops
  • Supportive therapy: Intrauterine blood transfusion
  • 5. Chronic infection with anemia
  • Preferred regimen: IVIG and transfusion
  • 6.Chronic infection without anemia
  • Preferred regimen: IVIG
Note (1): Diagnostic tools are IgM and Igb antibody titers.Perhaps better is blood Parvovirus PCR.
Note (2): Dose of IVIG not standardized; suggest 400 mg/kg IV of commercial IVIG for 5 or 10 days or 1000 mg/kg IV for 3 days.
Note (3): Most dramatic anemias in pts with pre-existing hemolytic anemia.
Note (4): Bone marrow shown erythrocyte maturation arrest with giant pronormoblasts.
  • Human polyomavirus (BK virus) treatment
  • Note (1): For those who are hypogammaglobulinemic, we administer intravenous immunoglobulins (IV IG) in replacement doses of 500 mg/kg. Quantitative immunoglobulins should be checked two to three months later to determine whether hypogammaglobulinemia has recurred. Intravenous immunoglobulins (IV IG) is also an option in certain settings, based upon polymerase chain reaction (PCR) and kidney biopsy results. IVIG may contain antibodies against BK and JC virus since these viruses are ubiquitous in the general population.
  • Note (2): The goals of decreased immunosuppressive therapy are to restrain viral replication without triggering rejection.
  • Note (3): Reduced immunosuppression (defined as lowering mean doses of Mycophenolate and Tacrolimus) resulted in the successful elimination of viremia (mean period of six months) and allograft survival.
  • Note (4): Alternative approaches to reducing immunosuppression have also been effective
  • 4.1 Changing from Tacrolimus to low-dose Cyclosporine not only reduces the effect of the Calcineurin inhibitor, but also reduces Mycophenolate concentrations.
  • 4.2 Replacing the Calcineurin inhibitor with Sirolimus, with or without discontinuation of the antimetabolite, has the advantage of avoiding the long-term Calcineurin inhibitor-related nephrotoxic effects.
  • 4.3 Lowering the dose of Calcineurin inhibitors may slow the loss of renal function.
  • Primary Regimens
  • Decrease immunosuppression if possible. (Cornerstone of Treatment)
  • Suggested antiviral therapy is based on anecdotal data. If progressive renal dysfunction:
  • Fluoroquinolone AND IVIG 500 mg/kg IV AND Leflunomide 100 mg for daily for 3 days, then 10-20 mg PO daily
  • If refractory to all of the above, add Cidofovir 5 mg/kg once per week for 2 weeks, then once every other week if refractory to all of the above
  • Ancillary Therapies in BK Virus Nephropathy
  • Cidofovir 0.25-1.0 mg/kg IV biweekly for 8 wk without Probenecid, prehydration recommended
  • Leflunomide 100 mg loading dose for 3 days, 20-60 mg/day, goal Leflunomide trough 50-100 ng/mL (consider lower trough goals of 20-40 ng/mL given hemolysis risk)
  • IV Ig 1-2 g/kg IV for 1-2 doses or 150 mg/kg IV biweekly for 8 wk
  • Fluoroquinolones-Ciproflaxacin 500 mg/day, duration dependent on virological response.
  • Progressive Multifocal Leukoencephalopathy (PML) caused by JC Virus ( John Cunningham virus) infections[417]
  • There is no specific antiviral therapy for JC virus infection.
  • The main treatment approach is to reverse the immunosuppression caused by HIV.
  • Initiate anti retroviral therapy (ART) immediately in ART-naive patients .
  • Optimize ART in patients who develop Progressive Multifocal Leukoencephalopathy in phase of HIV viremia on ART .
  • Corticosteroids may be used for Progressive Multifocal Leukoencephalopathy- immune reconstitution inflammatory syndrome (IRIS) characterized by contrast enhancement, edema or mass effect, and with clinical deterioration
  • Rabies treatment
  • Preferred regimen: no specific therapetics agents are available once the disease is established.
  • Note: There are vaccines and immunoglobulins available for postexposure prophylaxis
  • Postexposure prophylaxis
  • 1. For non immunized individuals
Wound cleansing, human rabies immunoglobulin - administer full dose infiltrated around any wound. Administer any remaining volume IM at other site anatomically distant from the wound. Administer vaccine 1.0 ml, IM at deltoid area one each on days 0, 3, 7 and 14.
  • 2. For immunized individuals
Wound cleansing, do not administer human rabies immune globulin. Administer vaccine 1,0ml, IM at deltoid area one each on days 0 and 3.
  • Respiratory Syncytial Virus Return to Top
  • Respiratory syncytial virus treatment
  • Supportive therapy
  • Hydration and supplemental oxygen.
  • Routine use of Ribavirin not recommended. Ribavirin therapy associated with small increases in O2 saturation.
  • No consistent decrease in need for mechanical ventilation or ICU stays. High cost, aerosol administration and potential toxicity[418]
  • Note (1): In adults, Respiratory syncytial virus accounted for 10.6% of hospitalizations for pneumonia, 11.4% for COPD, 7.2% for asthma & 5.4% for CHF in pts >65 yrs of age [419]. Respiratory syncytial virus caused 11% of clinically important respiratory illnesses in military recruits[420]
  • Note (2): Respiratory Syncytial Virus major cause of morbidity in neonates/infants.
  • Note (3): Nucleic acid test now approved to detect 12 respiratory viruses (xTAG Respiratory Viral Panel, Luminex Molecular Diagnostics).
  • Prevention of Respiratory syncytial virus
  • 1. In children <24 months old with chronic lung disease of prematurity (formerly broncho-pulmonary dysplasia) requiring supplemental oxygen or
  • 2. In premature infants (<32 wks gestation) and <6 months old at start of Respiratory syncytial virus season or
  • 3. In children with selected congenital heart diseases.
  • Preferred regimen for prevention of Respiratory syncytial virus: Palivizumab (Synagis) 15 mg per kg IM q month Nov.-April[418]
Note : Significant reduction in Respiratory syncytial virus hospitalization among children with congenital heart disease[421]
  • Supportive therapy
  • 1. Symptomatic treatment-Ipratropium bromide intranasal (2 sprays tid) AND Clemastine 1.34 mg 1–2 tab PO bid–tid (over the counter)
  • 2. Symptomatic relief by Ipratropium nasal spray decreases rhinorrhea and sneezing vs placebo.[422] AND Clemastine (an antihistamine) decreases sneezing, rhinorrhea but associated with dry nose, mouth & throat in 6–19%.[423]OR Oral pleconaril given within 24 hrs of onset reduced duration (1 day) & severity of “cold symptoms” in DBPCT (p < .001).[424]
  • Note (1): No antiviral treatment indicated . [425]
  • Note (2): Found in half of children with community-acquired pneumonia; role in pathogenesis unclear (CID 39:681, 2004). [426]
  • Note (3): High rate of rhinovirus identified in children with significant lower resp tract infections [427]
  • Treatment of diarrhoea caused by rotavirus
  • Rehydration with oral rehydration salts (ORS) solution. oral rehydration salts (ORS) solution is a mixture of clean water, salt and sugar. It costs a few cents per treatment. oral rehydration salts (ORS) solution is absorbed in the small intestine and replaces the water and electrolytes lost in the faeces.
  • Zinc supplements-with zinc supplements reduce the duration of a diarrhoea episode by 25% and are associated with a 30% reduction in stool volume.
  • Rehydration with intravenous fluids in case of severe dehydration or shock.
  • Nutrient-rich foods the vicious circle of malnutrition and diarrhoea can be broken by continuing to give nutrient-rich foods including breast milk during an episode, and by giving a nutritious diet including exclusive breastfeeding for the first six months of life to children when they are well.
  • Consulting a health professional , in particular for management of persistent diarrhoea or when there is blood in stool or if there are signs of dehydration.
Note (1): Rotavirus and Escherichia coli are the two most common etiological agents of diarrhoea in developing countries.
Note (2): There is no antiviral drug to treat rotavirus infection. Antibiotic drugs will not help because antibiotics fight against bacteria not viruses.
Note (3): Rotavirus infection can cause severe vomiting and diarrhea. This can lead to dehydration (loss of body fluids). During rotavirus infection, infants and young children, older adults, and people with other illnesses are most at risk becoming dehydrated.
Note (4): Symptoms of dehydration include decrease in urination, dry mouth and throat, feeling dizzy when standing up. A dehydrated child may also cry with few or no tears and be unusually sleepy or fussy.
  • Prevention
  • Access to safe drinking-water
  • Use of improved sanitation
  • Hand washing with soap
  • Exclusive breastfeeding for the first six months of life
  • Good personal and food hygiene
  • Health education about how infections spread; and Rotavirus vaccination.

Smallpox

  • Supportive care is the mainstay of therapy.
  • Currently, there are no anti-viral drugs of proven efficacy.
  • Recently, animal studies suggest that cidofovir and its cyclic analogues, given at the time of or immediately after exposure, have promise for the prevention of cowpox, vaccinia, and monkeypox.
  • Patients need adequate hydration and nutrition, because substantial amounts of fluid and protein can be lost by febrile persons with dense, often weeping lesions.
  • 1. Secondary bacterial infection
  • Penicillinase-resistant antimicrobial agents should be used
  • If smallpox lesions are secondarily infected,
  • If bacterial infection endangers the eyes
  • Daily eye rinsing is required in severe cases.
  • Topical idoxuridine should be considered for the treatment of corneal lesions, although its efficacy is unproved for smallpox.
  • If the eruption is very dense and widespread.

  • 6.22.2.1.2. Recurrent falciparum malaria
  • 6.22.2.1.2.1. Failure within 28 days
  • Note: The recommended second-line treatment is an alternative ACT known to be effective in the region. Adherence to 7-day treatment regimens with Artesunate or Quinine both of which should be co-administered with Tetracycline, or Doxycycline or Clindamycin) is likely to be poor if treatment is not directly observed; these regimens are no longer generally recommended.
  • 6.22.2.1.2.2. Failure after 28 days
  • Note: All presumed treatment failures after 4 weeks of initial treatment should, from an operational standpoint, be considered new infections and be treated with the first-line ACT. However, reuse of Mefloquine within 60 days of first treatment is associated with an increased risk for neuropsychiatric reactions, and an alternative ACT should be used.
  • 6.22.2.1.3. Reducing the transmissibility of treated Plasmodium falciparum infections in low-transmission areas in patients with Plasmodium falciparum malaria (except pregnant women, infants aged < 6 months and women breastfeeding infants aged < 6 months)
  • Note: Single dose of 0.25 mg/kg biweekly Primaquine with ACT
  • 6.22.2.1.4. Treating uncomplicated Plasmodium falciparum malaria in special risk groups
  • 6.22.2.1.4.1. Pregnancy
  • First trimester of pregnancy : Quinine AND Clindamycin 10 mg/kg/day PO bid for 7 days
  • Second and third trimesters : Mefloquine is considered safe for the treatment of malaria during the second and third trimesters; however, it should be given only in combination with an artemisinin derivative.
  • Note (1): Quinine is associated with an increased risk for hypoglycaemia in late pregnancy, and it should be used (with clindamycin) only if effective alternatives are not available.
  • Note (2): Primaquine and Tetracyclines should not be used in pregnancy.
  • 6.22.2.1.4.2. Infants less than 5kg body weight
  • Note: They should be treated with an ACT at the same mg/kg bw target dose as for children weighing 5 kg.
  • 6.22.2.1.4.4. Large and obese adults
  • Note: For obese patients, less drug is often distributed to fat than to other tissues; therefore, they should be dosed on the basis of an estimate of lean body weight, ideal body weight. Patients who are heavy but not obese require the same mg/kg bw doses as lighter patients.
  • 6.22.2.1.4.5. Non-immune travellers
  • Note: Treat travellers with uncomplicated P. falciparum malaria returning to nonendemic settings with an ACT.
  • 6.22.2.1.4.6. Uncomplicated hyperparasitaemia
  • Note: People with P. falciparum hyperparasitaemia are at increased risk of treatment failure, severe malaria and death so should be closely monitored, in addition to receiving an ACT.

  • 6.22.2.2.1.2. Uncomplicated malaria caused by Plasmodium ovale, Plasmodium malariae or Plasmodium knowlesi malaria
  • Note: Resistance of P. ovale, P. malariae and P. knowlesi to antimalarial drugs is not well characterized, and infections caused by these three species are generally considered to be sensitive to Chloroquine. In only one study, conducted in Indonesia, was resistance to Chloroquine reported in P. malariae. The blood stages of P. ovale, P. malariae and P. knowlesi should therefore be treated with the standard regimen of ACT or Chloroquine, as for vivax malaria.

  • Preferred regimen: Primaquine 0.75 mg base/kg/day PO once a week for 8 weeks
  • Note: The decision to give or withhold Primaquine should depend on the possibility of giving the treatment under close medical supervision, with ready access to health facilities with blood transfusion services.
  • 6.22.2.2.2.3. Prevention of relapse in pregnant or lacating women and infants
  • Note: Primaquine is contraindicated in pregnant women, infants < 6 months of age and in lactating women (unless the infant is known not to be G6PD deficient)
  • 6.22.2.3. Treatment of severe malaria
  • 6.22.2.3.1. Treatment of severe falciparum infection with Artesunate
  • 6.22.2.3.1.1. Adults and children with severe malaria (including infants, pregnant women in all trimesters and lactating women)

  • Preferred regimen: Where intramuscular injections of artesunate are not available, treat with a single rectal dose (10 mg/kg) of Artesunate, and refer immediately to an appropriate facility for further care.
  • Note: Do not use rectal artesunate in older children and adults.
  • 6.22.2.3.3. Pregancy
  • Note: Parenteral artesunate is the treatment of choice in all trimesters. Treatment must not be delayed.
  • 6.22.2.3.4. Treatment of severe Plasmodium Vivax infection
  • Note: Parenteral Artesunate, treatment can be completed with a full treatment course of oral ACT or Chloroquine (in countries where Chloroquine is the treatment of choice). A full course of radical treatment with Primaquine should be given after recovery.
  • 6.22.2.3.5. Additional aspects of management in severe malaria
  • Fluid therapy: It is not possible to give general recommendations on fluid replacement; each patient must be assessed individually and fluid resuscitation based on the estimated deficit.
  • Blood Transfusion: In high-transmission settings, blood transfusion is generally recommended for children with a haemoglobin level of < 5 g/100 mL(haematocrit < 15%). In low-transmission settings, a threshold of 20% (haemoglobin,7 g/100 mL) is recommended.
  • Exchange blood transfusion: Exchange blood transfusion requires intensive nursing care and a relatively large volume of blood, and it carries significant risks. There is no consensus on the indications, benefits and dangers involved or on practical details such as the volume of blood that should be exchanged. It is, therefore, not possible to make any recommendation regarding the use of exchange blood transfusion.
