Recent reports of 12 confirmed cases of acquired immunodeficiency syndrome (AIDS) in Costa Rica have generated interest in the extent of spread of human T-lymphotropic virus type III/LAV (HTLV-III) in Latin America (1). To date, all cases of AIDS in Costa Rica have occurred in members of previously identified, high-risk groups, chiefly hemophiliacs. To examine the possibility of heterosexual transmission in Costa Rica, we utilized sera collected in a population-based case-control study of cervical cancer, conducted by the Costa Rican Demographic Association and other institution.
