Sudan is not among the most HIV affected countries in the world but does have a significant problem, especially among some population groups. The HIV prevalence rate of 0.67% reflects a concentrated epidemic among Most-at-Risk Populations (MARPs) in Sudan, namely female sexual workers (FSWs) and men who have sex with men (MSM). Yet, the risk of the epidemic spreading to the general population is high given that 25 % of MSM are married and 50% have sex with women. Current trends estimate an increase in HIV rate to 1.12% by 2015.
