  • Paratyphus
  • Rickettsiosis

Notifiable, potentially fatal infection with Salmonella typhi.

Ca. 500,000 dead year.

  • Pathogen
    • Salmonella typhi.
  • Transmission
    • Contamination of food by faeces.
  • The reservoir of the pathogen is humans. Asymptomtic excretion is also possible.

  • Fever, reduced general condition, constipation and cephalgia.
  • Erythematous macules (roseolae) may form abdominally and transform to papules as they progress.
  • Healing may occur with postinflammatory hyperpigmentation.

  • Clinical
  • Stool sample for pathogen detection.
  • Serological antibody detection.
  • If necessary, dermatopathological backup.

Dilated capillaries correlate with roseolae.
