Antiretroviral therapy for prevention of HIV transmission: potential role for people who inject drugs in Central Asia.

Interest in the use of antiretroviral therapy (ART) for prevention stems from mounting evidence from research studies demonstrating that ART is associated with a decrease in sexual HIV transmission among serodiscordant couples and, perhaps, in other populations at risk. There is paucity of data on the efficacy of ART for prevention in key populations, including persons who inject drugs (PWID). In this paper, we examine the current status of HIV services for PWID in Central Asia, the use of ART by this population and explore ART for prevention for PWID in this context. We also discuss research and implementation questions with relevance to such a strategy in the region.
