Scaling up HIV Treatment for MSM in Bangkok - What Does It Take?: A Modelling and Costing Study

The HIV epidemic amongst men who have sex with men (MSM) in Bangkok is substantial. The population size of MSM in Bangkok is 120,000-250,000, with approximately one-third (33.5 percent) considered high-risk, characterized by their young age, multiple partnerships, frequent unprotected anal intercourse, and sexual activities around MSM hotspots. In metropolitan Bangkok, HIV prevalence among MSM reportedly increased from 21 percent to 28 percent between 2000 and 2012. The Thai Working Group of Estimation and Projection (2013) projected an estimate of 39,000 new HIV infections would occur in Thailand during 2012-2016, based on the AIDS Epidemic Model (AEM).
