Searching for the HIV (human immunodeficiency virus) in south Sudan, Guinea Bissau, Cape Verde Islands, Iran, Nicaragua, El Salvador, Columbia.
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.
