Typhoid fever, caused by the bacterium Salmonella typhi, is a life-threatening bacterial infection. Typhoid fever is still common in the developing world, where it affects about 21 million people annually.

Salmonella typhi lives only in humans. Persons with typhoid fever carry the bacteria in their bloodstream and intestinal tract. In addition, a small number of persons, called carriers, recover from typhoid fever but continue to carry the bacteria. Both ill persons and carriers shed S.typhi in their feces.

CDC: All travelers to Pakistan are at risk of getting XDR typhoid fever

You can get typhoid fever if you eat food or drink beverages that have been handled by a person who is shedding S. typhi or if sewage contaminated with S. typhi bacteria gets into the water you use for drinking or washing food. Therefore, typhoid fever is more common in areas of the world where handwashing is less frequent and water is likely to be contaminated with sewage.
