This aims to describe HIV/STI prevalence and drug use among MSM in Ha Noi, Hai Phong, and Can Tho, Viet Nam.

Neisseria Gonorrhoea (NG) was 3.4%, 0.3%, and 3.2% in rectal and 0.0%, 0.3%, and 0.9% in genital in Ha Noi, Hai Phong, and Can Tho, respectively. Consistently condom use with non-commercial male partners in past month was 59.1%, 78.6%, and 62.3% in Ha Noi, Hai Phong, and Can Tho, respectively. Reported ever drug use was 13.2%, 13.1%, and 1.5% in Ha Noi, Hai Phong, and Can Tho, respectively. Opiate in urinalysis was 5.3%, 11.0%, and 1.2% in Ha Noi, Hai Phong, and Can Tho, respectively.
