Foodborne illness
Epidemiology
Asymptomatic subclinical infection may help spread these diseases, particularly Staphylococcus aureus, Campylobacter, Salmonella, Shigella, Enterobacter, Vibrio cholerae, and Yersinia. For example, as of 1984 it was estimated that in the United States, 200,000 people were asymptomatic carriers of Salmonella.
