Sexual transmission of typhoid fever: A multistate outbreak among men who have sex with men

Abstract

In August 2000, the Ohio Department of Health reported a cluster of men with typhoid fever who denied having traveled abroad. To determine the cause and the extent of the outbreak, an epidemiological investigation was initiated in which 7 persons in Ohio, Kentucky, and Indiana with culture-confirmed Salmonella enterica serotype Typhi infection and 2 persons with probable typhoid fever were evaluated; all were men, and all but one reported having had sex with 1 asymptomatic male S. Typhi carrier. We document sexual transmission of typhoid fever, which may be acquired by means of oral and anal sex, as well as via food and drink.
