Is typhoid contagious?

Page last updated 10 July 2018

Yes. The transmission if typhoid usually occurs when contaminated food and water are ingested. The time between contracting typhoid and the onset of symptoms (known as the incubation period) is usually around 8 to 14 days, however it can be shorter or longer. 

Because it is transmitted via food and water, in general, typhoid is more common in less developed countries with poor sanitation, poor food handling standards and unsafe drinking water. Shellfish as well as raw fruits and vegetables are the types of foods most often associated with illness, and flies may also help with transfer of bacteria to food.
