Compared prevalence of infections by HIV-1 and HIV-2 during a 2-year period in suburban and rural areas of Ivory Coast.

ABSTRACT

PIP: The testing for human immune deficiency virus type 2 (HIV-2) antibodies of 794 sera collected in July-August 1985 in the 4 regions of Korhogo, Bondoukou, Man, and Bouake in Ivory Coast and the collection and testing for HIV-1 and HIV-2 antibodies of 1126 sera collected in July-August 1987 in the same regions and age groups showed a remarkable stability in the prevalence of infection by these 2 retroviruses (0.7 and 0.4% in 1985 vs 0.9 and 0.2% in 1987, respectively for HIV-1 and HIV-2) in rural areas. In contrast, the increase in prevalence of both HIV-1 (from 1-1.9%) and HIV-2 (from 0.8-1.3%) from 1985-87 in the urban population was accompanied by a sharp increase during these 2 years in the number of AIDS cases in regional hospitals.
