Condom use and HIV awareness rate need to enhance further among female sex workers. The proportion of female sex workers who attended VCT and knew their HIV testing result and the proportion of female sex workers who reached intervention in last year both increase. HIV prevalence rate among female sex workers is generally low, but high risk behaviors are still alarming. It is necessary to take more comprehensive and effective prevention measures and intervention.
