Trends in Incidence of HIV and Syphilis Among Men Who Have Sex with Men - Tianjin Municipality, China, 2013-2022.

ABSTRACT

What is already known about this topic? Given the common modes of transmission, outbreaks of both human immunodeficiency virus (HIV) and syphilis are primarily observed in men who have sex with men (MSM). However, minimal research has been conducted to concurrently evaluate the rates and trends of HIV and syphilis incidence within this community in China. What is added by this report? This manuscript presents the incidence rates and associated factors of HIV and syphilis in MSM in Tianjin based on data derived from a decade-long cohort study. Intriguingly, it depicts a decreasing trend in HIV incidence juxtaposed with an increasing incidence of syphilis among this population in Tianjin. What are the implications for public health practice? The interconnected risk factors for HIV and syphilis pose significant hindrances to disease control. Our study underscores the urgent need for improved intervention strategies specifically aimed at MSM to mitigate the propagation of both infections.
