Reduction in risk-taking behaviors among MSM in Senegal between 2004 and 2007 and prevalence of HIV and other STIs. ELIHoS Project, ANRS 12139.

An epidemiological survey conducted in Senegal in 2004 among men having sex with men (MSM) revealed high HIV prevalence and a high rate of risky behaviors within this population. Consequently, several prevention campaigns targeting MSM were implemented. A second survey was carried out in 2007 to assess the impact of these measures.

Surprisingly high prevalence of subtype C and specific HIV-1 subtype/CRF distribution in men having sex with men in Senegal.

Background: Recent reports showed the high vulnerability for HIV infection of men who have sex with men (MSM) in Africa. Here, we report the HIV-1 variants that circulate among MSM in Senegal.

Methods: HIV-1 subtype/circulating recombinant form (CRF) was determined in an 1800-base pair fragment of pol for 70 HIV-1-positive samples from MSM.
