However, data from the national sentinel surveillance for HIV/AIDS indicated magnitudes and trends in HIV prevalence vary substantially across different at-risk populations: e.g. 0.6% HIV prevalence among female sex workers (FSW) in 2009 [2] and increases from 1.4% in 2001 to 5.3% in 2009 among men who have sex with men (MSM) [4, 5] , and from 5.9% in 2002 to 9.3% in 2009 among injecting drug users (IDU) [2, 6] .	./cache/cord-342076-3a6aky7i.txt	./txt/cord-342076-3a6aky7i.txt
