What this trial studies

This observational study aims to evaluate the burden and transmission dynamics of Mycoplasma genitalium (MG) infection among men who have sex with men in Hong Kong. It involves a cross-sectional approach where participants will complete an online survey and provide self-collected samples for laboratory testing of STIs, including MG, Chlamydia trachomatis, and Neisseria gonorrhoeae. Additionally, a mathematical modeling component will simulate the transmission dynamics of MG and analyze the effectiveness of various test-and-treat strategies. The study seeks to recruit approximately 920 eligible participants.

Why it matters

Potential benefit: If successful, this study could enhance understanding of Mycoplasma genitalium transmission and inform effective prevention strategies for at-risk populations.

How similar studies have gone: While there have been studies on other sexually transmitted infections, this specific focus on Mycoplasma genitalium transmission dynamics in this population is relatively novel.
