A new sentinel survey of pregnant women who underwent voluntary AIDS testing in maternity clinics, indicates that 4.3 percent of Guinea's adult population is infected with HIV. That represents a big jump from the figure of 2.8 percent suggested by the previous sentinel survey carried out in 2001. The new survey was conducted last year by the government's National Council for Fighting AIDS (CNLS) and the German aid agency GTZ. It was funded by the World Bank.
