==Overview==
Despite the existence of different [[species]] of ''Ebola virus'', according to the data collected throughout the last 40 years, a common [[syndrome|clinical syndrome]] has been described among these different [[filovirus|filoviroses]], with the difference residing essentially in the severity of the presentation and respective [[mortality rate]].
Ebola hemorrhagic fever is commonly associated with fever on physical examination at admission. At advanced stages of the disease, physical examination findings are more pertinent and often include unstable vital signs, such as tachycardia or relative bradycardia, orthostatic hypotension, and tachypnea. Physical examination may also be remarkable for abdominal tenderness and distension, evidence of mucosal or visceral bleeding, and neurological impairment.<ref name="FeldmannGeisbert2011">{{cite journal|last1=Feldmann|first1=Heinz|last2=Geisbert|first2=Thomas W|title=Ebola haemorrhagic fever|journal=The Lancet|volume=377|issue=9768|year=2011|pages=849–862|issn=01406736|doi=10.1016/S0140-6736(10)60667-8}}</ref><ref name="FormentyHatz1999">{{cite journal|last1=Formenty|first1=Pierre|last2=Hatz|first2=Christophe|last3=Le Guenno|first3=Bernard|last4=Stoll|first4=Agnés|last5=Rogenmoser|first5=Philipp|last6=Widmer|first6=Andreas|title=Human Infection Due to Ebola Virus, Subtype Côte d'Ivoire: Clinical and Biologic Presentation|journal=The Journal of Infectious Diseases|volume=179|issue=s1|year=1999|pages=S48–S53|issn=0022-1899|doi=10.1086/514285}}</ref><ref name="pmid10667555">{{cite journal| author=Gradon J| title=An outbreak of Ebola virus: lessons for everyday activities in the intensive care unit. | journal=Crit Care Med | year= 2000 | volume= 28 | issue= 1 | pages= 284-5 | pmid=10667555 | doi= | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=10667555  }} </ref>
Attending to the mechanism of [[infection]] and pathogeny of the [[virus]] in human [[cells]], ''Ebola hemorrhagic fever'' usually begins with an acute onset of high [[fever]], [[chills]] and [[hemorrhage]] observed on [[physical examination]]. Other pertinent findings may include swollen [[joints]], [[weakness]], [[rash]] and [[red eyes]]. Also, the high [[fever]] present in this condition may lead to the development of relative [[bradycardia]], similarly to [[typhoid fever]]. <ref name="FeldmannGeisbert2011">{{cite journal|last1=Feldmann|first1=Heinz|last2=Geisbert|first2=Thomas W|title=Ebola haemorrhagic fever|journal=The Lancet|volume=377|issue=9768|year=2011|pages=849–862|issn=01406736|doi=10.1016/S0140-6736(10)60667-8}}</ref><ref name="FormentyHatz1999">{{cite journal|last1=Formenty|first1=Pierre|last2=Hatz|first2=Christophe|last3=Le Guenno|first3=Bernard|last4=Stoll|first4=Agnés|last5=Rogenmoser|first5=Philipp|last6=Widmer|first6=Andreas|title=Human Infection Due to Ebola Virus, Subtype Côte d'Ivoire: Clinical and Biologic Presentation|journal=The Journal of Infectious Diseases|volume=179|issue=s1|year=1999|pages=S48–S53|issn=0022-1899|doi=10.1086/514285}}</ref><ref name="pmid10667555">{{cite journal| author=Gradon J| title=An outbreak of Ebola virus: lessons for everyday activities in the intensive care unit. | journal=Crit Care Med | year= 2000 | volume= 28 | issue= 1 | pages= 284-5 | pmid=10667555 | doi= | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=10667555  }} </ref>

==Physical Examination==
The general appearance of the patient will depend on the stage of evolution of the disease. However, common presentations include a patient who shows [[prostration]], who may be [[nauseated]] and [[vomiting]], with [[shortness of breath|difficult in breathing]] and in [[dysphagia|swallowing]] and possibly showing some kind of [[hemorrhage]], most typically [[retinal]] [[hemorrhage]] and/or [[bleeding gums]].<ref name="BorchertMutyaba2011">{{cite journal|last1=Borchert|first1=Matthias|last2=Mutyaba|first2=Imaam|last3=Van Kerkhove|first3=Maria D|last4=Lutwama|first4=Julius|last5=Luwaga|first5=Henry|last6=Bisoborwa|first6=Geoffrey|last7=Turyagaruka|first7=John|last8=Pirard|first8=Patricia|last9=Ndayimirije|first9=Nestor|last10=Roddy|first10=Paul|last11=Van der Stuyft|first11=Patrick|title=Ebola haemorrhagic fever outbreak in Masindi District, Uganda: outbreak description and lessons learned|journal=BMC Infectious Diseases|volume=11|issue=1|year=2011|pages=357|issn=1471-2334|doi=10.1186/1471-2334-11-357}}</ref>

The general appearance of the patient depends on the stage of the disease. Typically, patients demonstrate [[prostration]], may be [[nauseated]] and [[vomiting]], and less commonly present with signs of hemorrhage, such as epistaxis or gingival bleeding. In later stages of the disease, patients are often brought with convulsions or are in a state of shock, stupor, or coma.<ref name="BorchertMutyaba2011">{{cite journal|last1=Borchert|first1=Matthias|last2=Mutyaba|first2=Imaam|last3=Van Kerkhove|first3=Maria D|last4=Lutwama|first4=Julius|last5=Luwaga|first5=Henry|last6=Bisoborwa|first6=Geoffrey|last7=Turyagaruka|first7=John|last8=Pirard|first8=Patricia|last9=Ndayimirije|first9=Nestor|last10=Roddy|first10=Paul|last11=Van der Stuyft|first11=Patrick|title=Ebola haemorrhagic fever outbreak in Masindi District, Uganda: outbreak description and lessons learned|journal=BMC Infectious Diseases|volume=11|issue=1|year=2011|pages=357|issn=1471-2334|doi=10.1186/1471-2334-11-357}}</ref>

Overview

Ebola hemorrhagic fever is commonly associated with fever on physical examination at admission. At advanced stages of the disease, physical examination findings are more pertinent and often include unstable vital signs, such as tachycardia or relative bradycardia, orthostatic hypotension, and tachypnea. Physical examination may also be remarkable for abdominal tenderness and distension, evidence of mucosal or visceral bleeding, and neurological impairment.[1][2][3]

Physical Examination

Appearance of the Patient

The general appearance of the patient depends on the stage of the disease. Typically, patients demonstrate prostration, may be nauseated and vomiting, and less commonly present with signs of hemorrhage, such as epistaxis or gingival bleeding. In later stages of the disease, patients are often brought with convulsions or are in a state of shock, stupor, or coma.[4]

Vitals

Temperature

  • High-grade fever is often present in more than 80% of patients. Fever is the most common presenting sign of Ebola virus infection.

  • Tachypnea often precedes death during final hours of infection.

Skin

Hemorrhagic manifestations tend to occur during the more severe stages of the disease and may include:[1]
