Paratyphoid fever

A rare form of salmonellosis caused by Salmonella enterica serovar Paratyphi A, B and C, characterized by typical symptoms of enteric fever including high fever, headache, abdominal pain and intestinal symptoms, dry cough, chills, and rashes, followed by a long period of recovery. The infection can be complicated by intestinal hemorrhage and perforation, as well as cardiac involvement, and may even be fatal. Transmission of the pathogen is via the fecal-oral route, with humans as the sole reservoir of infection.
