H. Ousseini et al., SEROPREVALENCY OF HIV-INFECTION AMONG TOU AREGS AND PEULS-BORORO OF NIGER, Bulletin de la Societe de pathologie exotique et de ses filiales, 88(3), 1995, pp. 124-125
A seroepidemiological study of endemic treponematosis (bejel) in Niger
allows us to realise an anonymus non correlated screening of VIH infe
ction in Nomads: Touaregs of Tchirozerine (Agadez), Peuls Bororo of Be
rmo (Maradi). On the 424 Touaregs screened only one was seropositive t
o VIH2 infection confirmed with Western blot that means 0,23 % of sero
prevalency comparable to that 0,50 % found in the general population.
The seroprevalency of trepronematosis (VDRL + TPHA +) is 7 % in the ra
nge of 5 to 15 years old (80 %), period which corresponds to the trans
mission of Bejel. Moreover this population don't travel to the seabord
er countries. Concerning the 213 of the Peuls Bororo screened we had o
nly 3 indetermined reactions to Western blot I 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 sexuel i
ntercourse and exodus period to the seaborder countries, where 66 % of
our VIH patients are infected.
