HIV-2 antibodies in serum samples from Maharashtra state.

Two hundred serum samples were tested to detect the presence of HIV-2 infection in Maharashtra state. The serum samples were derived from various groups including those with high risk behaviour for HIV infection. All samples were tested by three combined HIV-1 and HIV-2 ELISA kits. The reactivity was confirmed by LiaTek HIV 1+2 immunoblot. The study confirmed that HIV-2 infection exists in Maharashtra, as 14 samples showed antibodies to HIV-2 and 14 showed antibodies to both HIV-1 and HIV-2. Antibodies to HIV-2 or HIV-1 and HIV-2 were detected mainly in persons with high risk behaviour.
