[The seroprevalence of human immunodeficiency virus infection (HIV) in the Touaregs and Peuls Bororo in Niger].
A seroepidemiological study of endemic treponematosis (bejel) in Niger allows us to realise an anonymous non correlated screening of VIH infection in Nomads: Touaregs of Tchirozerine (Agadez), Peuls Boro of Bermo (Maradi). On the 424 Touaregs screened only one was seropositive to VIH2 infection confirmed with Western blot that means 0.23% of seroprevalency comparable to that 0.50% found in the general population. The seroprevalency of trepronematosis (VDRL + TPHA+) is 7% in the range of 5 to 15 years old (80%), period which corresponds to the transmission of Bejel. Moreover this population don't travel to the seaborder countries. Concerning the 213 of the Peuls Bororo screened we had only 3 undetermined reactions to Western blot 1 and 2, despite the high seroprevalence of the treponematosis (VDRL+ TPHA+): 22% mostly in the subjects of more than 15 years old (89.36%) which is the sexual intercourse and exodus period to the seaborder countries, where 66% of our VIH patients are infected.
