Abstract

Two hundred fifty-one pools of mosquitoes were caught in 15 separate trap sites in parks of Essex County, New Jersey, and examined for the presence of hepatitis B antigen (HB Ag). Ten of the pools were HB Ag-positive. These were found at trap sites in parks adjacent to areas of high population density and low economic level, after periods of crowding over a weekend. Pools obtained from low population density, high socioeconomic areas were uniformly HB Ag-negative. The possible role of HB Ag-positive mosquitoes in transmission of viral hepatitis depends on the degree of mosquito infestation and the epidemiological characteristics of the human population involved.
