Background: The prevalence of HIV within the general population, according to the last survey of 2012 in Niger, is 0.4%. However, there are key populations more displayed at the risk of HIV (sex workers [SW], men sex men, prisoners). This study aimed to determine HIV prevalence and describe knowledge, attitudes and practices among SW in Niger.
Methods: We conducted a cross-sectional survey from November to December 2015. The SW is a woman who claims to have sexual intercourse against property or money; sample size: 781 for the behavioral survey selected in 8 regions and 602 for serological test; participants were identified with the support of SW leaders. Data were collected on electronic questionnaire. Chi2 test was used to compare proportions. Unadjusted prevalence ratios (PR) and 95% CI were calculated.
Results: Mean age: 28.5 years 95% CI [27.9-29.1], SD: 8.7; 379(48.5%) unschooled; 387 (49.6%) identified as singles; 370 (47.4%) divorced and 24 (3%) married. Average exercise period as SW: 3.9 years 95% CI [3.6-4.1]. HIV prevalence among SW: 100 (16.6%) of 602 tested, [95% CI (13.8-19.8)]; 10 cases/13 (76.9%) [95% CI (49.7-91.2)] were from Diffa. HIV prevalence was higher in the group of unschooled SW: 53/287 (18.5%) compared with those who attended school: 47/315 (14.9%), but this difference is not statistically significant, p = 0.27. PR = 1.24 [0.84 -1.98]. 156 (20%) know the three main prevention Methods:; 352 (45.1%) reject misconceptions (to know that mosquitoes bites does not transmit the HIV; eating with someone living with the HIV does not transmit the virus); 71 (9.1%) know ways to prevent and reject misconceptions. 231 (29.6%) had their first sexual intercourse before 15 years. 698 (89.4%) use condom for every paid sex.
Conclusion: HIV prevalence among SW is very high. Proximity prevention strategies should be intensified with this target group.
