“…Inconsistent or ineffective condom use, a history of STD, and lack of HIV testing have been widely considered key HIV risks (Hong et al, 2012; Li et al, 2010; Li et al, 2011; Rusch et al, 2010; Zermiani et al, 2012; Zhang et al, 2011). Even though condom use can effectively prevent HIV transmission and other sexually transmitted infections among FSWs, only a small proportion of FSWs consistently and properly use condoms with their clients (Zhang et al, 2011; Li et al, 2010; Li et al, 2011; Lau et al, 2010). Recent studies in China revealed that 47.1% of FSWs had consistently used condoms during the previous month (Zhang et al, 2011), 15% consistently had used condoms throughout their sex lives (Yang et al, 2005), and 60% of FSWs knew how to use condoms effectively (Li et al, 2011; Yang et al, 2005).…”
