What is already known on this topic?

Continuing, increasing, and reemerging epidemics of human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs) have been reported among men who have sex with men (MSM) in the United States and elsewhere in the industrialized world. Limited information is available about the prevalence and incidence of HIV and STI infection among MSM in lower-income and lower-middle income countries.

What is added by this report?

Among MSM followed at a sexual health clinic in Bangkok, Thailand, during 2005-2011, the prevalence of HIV infection was 28.3% and of all stages of syphilis was 9.8%. Among those returning for HIV or syphilis testing before the end of 2011, the incidence of HIV infection was 6.3 per 100 person-years and of syphilis was 3.6 per 100 person-years.

What are the implications for public health practice?

The ongoing epidemics of HIV and syphilis infection in Bangkok MSM underscores the need for innovative and increased efforts to reduce their spread in this population.
