Abstract
Four HIV-2 and 8 HIV-1 infections were detected when serum specimens from 422 persons from high-endemic areas were examined with 6 different commercial ELISA tests. 41 specimens showed a positive result in at feast one of the assays. 12 of these were confirmed as anti-HIV positive. One of the anti-HIV-2 specimens was negative in the Abbott recombinant HIV-1 test but positive in the ELAVIA II and the 4 HIV-1/HIV-2 combination tests. The 4 HIV-2 positive individuals originated from West Africa.
