Hepatitis A is a self-limited, virally mediated infection of the liver. The usual mode of transmission is by the fecal-oral route. Employees of food-service establishments who are infected with the hepititus A virus can transmit the disease when handling food products. The Centers for Disease Control and Prevention recommends the use of the hepatitis A vaccine among dietary workers who may be at risk for contracting and spreading the disease. Because hepatitis A infection can often be a subclinical disease, the incidence of cases reported is not indicative of its true prevalence. The objective of this study was to document the seroprevalence of hepatitis A among hospital dietary workers. Dietary workers at a suburban hospital were interviewed to determine if they had been exposed to hepatitis A and if they had a history of hepatitis A infection.
