Overview

Symptoms of typhoid fever, which usually begin to develop 5 to 21 days after ingestion of the causative organism, include fever, headache, malaise, and bradycardia. If left untreated, the patient will develop complications in the second or third week of illness such as intestinal perforation, intestinal hemorrhage, typhoid encephalopathy, meningitis, disseminated intravascular coagulation, miscarriage, or relapse.[1][2][3][4][5][6][7][8][9][10][11][12] Without therapy, the illness may last for 3 to 4 weeks and mortality rates range between 12% and 30%. The prognosis of typhoid fever varies depending on the local incidence rate. The mortality rate of typhoid fever in endemic areas is 1-4% with treatment, while it is less than 1% with treatment in areas with low incidence of typhoid fever.[13][14]

Natural history

The symptoms of typhoid fever usually develop 5 to 21 days after ingestion of the causative organism.[12][15][16][17][18]

First Week Second Week[12] Third Week Fourth Week[16][19]
  • Prostration
  • High grade fever which plateaus around 40°C
  • Bradycardia (Sphygmo-thermic dissociation), classically with a dicrotic pulse wave
  • Delirium or agitation (nervous fever)
  • Rose spots on the lower chest and abdomen (1/3 patients)
  • Rhonchi in lung bases
  • Abdominal pain (right lower quadrant)
  • Diarrhea (six to eight stools/day), green with a characteristic smell, comparable to pea-soup[20]
  • Constipation
  • Resolution
  • Chronic carrier state[14]
  • Death

Complications

Common complications of typhoid fever include:[2][3][4][5][6][7][9][10][11][21][22]

Gastrointestinal

Neurologiocal

Cardiovascular

Respiratory

Heamatologic

Other

Prognosis

Worldwide, the prognosis of typhoid fever varies depending on the local incidence rate. The mortality rate of typhoid fever in endemic areas is 1-4% with treatment as compared to 10-30% without treatment.[13] However, the mortality rate in the areas with low incidence of typhoid fever is less than 1% with treatment.[14]

  • Favorable prognostic factors:
  • Early diagnosis and treatment[25]
  • Susceptibility to drugs[26]
  • Less virulent strain[27]
  • Good compliance
  • Poor prognostic factors:
