Typhoid fever, or “enteric fever,” is an acute systemic disease caused by the Gram-negative bacillus Salmonella typhi. Transmission may occur person-to-person or by ingestion of food or water contaminated by the urine or feces of acute cases or carriers. Common symptoms include insidious onset of persistent fever, headache, malaise, anorexia, constipation (more commonly than diarrhea), bradycardia, enlargement of the spleen, and rose spots on the trunk. Humans are the only known reservoir for S. typhi. Vaccine is available to those at high risk or travelers.
