[Detection of HIV antibodies in a rural region of a developing country].

A HIV seroprevalence among 312 antenatal mothers at their first visit to the Idjwi isle's hospital, in Zaïre, near Rwanda, and among 61 other patients, was made with the HIV1 Immunocomb of PBS Orgenics during one year: 1989. The seroprevalence is 0.32%, in this rural area, as was confirmed by Western-Blot. A panel of this 51 "false and true positive" and 13 negative african sera was tested with one other ELISA and two new rapid tests used in France, HIV CHEK 1 + 2 and TEST PACK HIV1/HIV2 to evaluate efficacy under conditions in which transfusions are normally given. These were performed within 15 mn of receipt of blood from a donor in Zaïre.
