“…Substance use has also been associated with increased vulnerability among FSWs to HIV/STIs (Medhi et al, 2013; Strathdee et al, 2008). Most studies report that two-thirds or more of FSWs have used alcohol in recent months (Chersich, Bosire, King’ola, Temmerman, & Luchters, 2014; Fernandes et al, 2014; Leslie, Ahern, Chinaglia, Kerrigan, & Lippman, 2013; Odukoya, Sekoni, Onajole, & Upadhyay, 2013), and a significant percentage meet criteria for hazardous and harmful drinking (Chersich et al, 2014).
