title: Searching for the HIV (human immunodeficiency virus) in south Sudan, Guinea Bissau, Cape Verde Islands, Iran, Nicaragua, El Salvador, Columbia.
abstract: In the spring of 1986, 3.473 human blood samples were serologically screened for HIV-antibodies. The methods used were ELISA (enzyme-linked immunosorbent assay), immunoblotting (Western Blot) and the indirect immunofluorescence assay (IFA). The blood samples were collected from males and females of all age groups in: South Sudan (Melut District in 1981 and 1983), Guinea Bissau (1983), on the Cape Verde Islands (1983/84), in Iran (1985), Nicaragua (1984), El Salvador (1984) and Columbia (1984). 18 out of 1.614 sera from South Sudan, 5 out of 93 sera from Guinea Bissau, 1 out of 289 tested sera from El Salvador were confirmed to be positive. None of the sera from Iran and Nicaragua were HIV-antibody positive.
