title: HIV-1 and HIV-2 in Ghana, west Africa: community surveys compared to surveys of pregnant women.
abstract: We conducted a population-based serosurvey of HIV-1/2 in 2,410 residents of two urban and two rural areas of southern Ghana, West Africa and compared the results to serosurveys of 1,417 pregnant women. Using conservative criteria, we found the prevalence of HIV-1/2 in community survey adults (> 15 years old) to be 1.5% in women and 1.0% in men. Among pregnant women, the prevalence was 9.3% in one rural area but only 1.0% in other areas. Many samples, especially among the pregnant women were HIV-1 and -2 dual reactive on serology. We attribute the disparity between prevalence in the community survey participants and pregnant women to local socio-economic factors. Women in this area have a tradition of working throughout West Africa as trader/ commercial sex workers. When pregnant or ill, they return to their home villages to be with their families. HIV surveillance programs which rely on pregnant women need to be sure that sampled populations are truly typical of the communities they are intended to represent.
