title: HIV 1 and HIV 2 prevalence of seropositivity in a population of West Africa.
abstract: In the month of August 1986, tests for anti-HIV 1 and anti-HIV 2 antibodies were performed in people coming to the hospital of Tanguietà (North Benin) (401 subjects) and in people working in the same hospital (23 subjects). The study revealed an anti-HIV 1 antibody prevalence of 0.4% (2/424) and an anti-HIV 2 prevalence of 0.2% (1/419). Seropositivity for both antibodies (anti-HIV 1 and anti-HIV 2) was found in one case; the other case was positive only for anti-HIV 1. The changing composition of the population due to frequent migratory displacements lead us to expect some possible alterations of the registered data in the future.
