Globally, men who have sex with men (MSM) are disproportionately burdened by Human Immunodeficiency Virus (HIV) and other Sexually Transmitted Infections (STIs). In 2017, the Sexual Health Promotion clinic at Hanoi Medical University launched a baseline survey as part of a cohort study to describe HIV and STIs among a representative sample of MSM in Hanoi, Vietnam. This literature review was performed to understand the most recent findings in HIV/STI epidemiology and prevention/intervention strategies in worldwide MSM population.
The author performed searches of literature on HIV/STI epidemiology and prevention/control among MSM population with PubMed, Embase, and Web of Science. All literature was logged in a color-coded Excel spreadsheet for easy information extraction.
Over 1600 publications were published in the last 5 years. Upon literature review, 190+ articles were determined to be relevant to the Hanoi MSM cohort study.
Prevalence of HIV, syphilis, Chlamydia Trachomatis, and Neisseria Gonorrhoeae infections was high among Hanoi MSM. Worldwide, pre-exposure Prophylaxis (PrEP) successfully decreases HIV incidence but leads to an increase in STI incidence, likely due to risk compensation behaviors.
