Answer

United States

Since 1900, improved sanitation and successful antibiotic treatment have steadily decreased the incidence of typhoid fever in the United States. In 1920, 35,994 cases of typhoid fever were reported. In 2006, there were 314.

Between 1999 and 2006, 79% of typhoid fever cases occurred in patients who had been outside of the country within the preceding 30 days. Two thirds of these individuals had just journeyed from the Indian subcontinent. The 3 known outbreaks of typhoid fever within the United States were traced to imported food or to a food handler from an endemic region. Remarkably, only 17% of cases acquired domestically were traced to a carrier. [23]
