Hepatitis A outbreak originating in a day care center: A community case report

A community outbreak of hepatitis A is described, involving 23 persons in a small town in central Israel. Seventy-four percent of the cases were related to a contact with toddlers in one nursery class in a day care center. There were no overt cases in that class itself. The mode of transmission exemplified in this community underlines the difficulties in identifying a common source of hepatitis A infection, which is necessary for the elimination of a further spread of the disease.
