To assess human immunodeficiency virus (HIV), syphilis, and behavioral risk factors among men who have sex with men (MSM) in southwestern China, where HIV started as a drug-driven epidemic, and shifted to mainly heterosexual transmission. These cross-sectional studies were conducted yearly in 2013, 2014, and 2015 in Guangxi, China. A total of 1,996, 1,965, and 1,697 participants were recruited in 2013, 2014, and 2015, respectively.

The prevalence of syphilis was 9.3% in 2013, 9.8% in 2014, and 6.1% in 2015. And HCV prevalence was 0.5% in 2013 and remained stable at 0.4% in 2014, and 2015.
