Abstract:
In Guinea Bissau, West Africa's little country, since 1989 to 1995 June the first 3091 patients with tuberculosis have been tested for HIV-1, and HIV-2 infections. During the first two years of epidemic surveillance the HIV-2 seroprevalence among tuberculotics was respectively 14.89% and 17.26%. Since 1991 it has been noticed besides an increase of seroprevalence for HIV-2 up to 20,27% in 1992, a constant increase for HIV-1 infection, associated or not with HIV-2. The Authors conclude that the epidemiologic pattern of Guinea Bissau is particularly interesting because in this country two epidemics (for HIV-1 and for HIV-2) have been followed since the beginning among tuberculotics allowing to study the natural history and epidemiologic evolution with particular accuracy.
