About Typhoid Fever

How is it transmitted?

Typhoid Fever is a bacterial illness normally transmitted by swallowing something contaminated with the bacteria (Salmonella enterica, serotype Typhi). Most commonly, Typhoid is contracted by ingesting contaminated food and water in countries with poor sanitation. Direct person-to-person transmission is less common but can occur. Stool (feces) from an infected person can contaminate surfaces, food, or water; another person can become infected if any bacteria enter the person’s mouth (“fecal-oral transmission”). The incubation period is 6-30 days.

Signs and symptoms

Illness onset is gradual and consists of increasing fatigue and a fever that increases daily, from low grade to as high as 102-104 degrees Fahrenheit (38-40 degrees Celsius). Other possible symptoms include stomach pains, headache, appetite loss, rash, diarrhea, and constipation. 


Typhoid fever is treated with antibiotics.


    • Hand washing, especially after using the bathroom and before eating/handling food.
    • Clean and disinfect contaminated areas.
    • If you are traveling to a country where typhoid is common, you should make a Travel Health appointment to discuss your vaccination options. You should be seen by a travel health provider at least 2 weeks before departure, in order to ensure adequate benefit before potential exposure.
