Sexually transmitted infections and demographic, clinical, and behavioral characteristics were prospectively collected at 6-month follow-up visits between October 2017 and November 2019.

The overall incidence of any reported STI was 91.9 per 1000 PYFU (95% confidence interval [CI], 85.8 \u201398.5). Among the 1634 STI episodes, there were 573 (35.1%) incident cases of syphilis, 497 gonorrhea (30.4%), and 418 chlamydia (25.6%). Men who have sex with men (MSM) younger than 50 years represented 21% of the study population, but accounted for 61% of reported STIs. Male sex (adjusted incidence rate ratio [aIRR], 2.03; 95% CI, 1.36\u20133.02), MSM (aIRR, 3.62; 95% CI, 2.88\u20134.55), age group 18\u201334 years (aIRR, 1.78; 95% CI, 1.51\u20132.10), history of sexual relationships with occasional partners (aIRR, 6.87; 95% CI, 5.40\u20138.73), and reporting injecting drug use (aIRR, 2.48; 95% CI, 1.91\u20133.23) were associated with a higher risk of incident STIs.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Sexually transmitted infections were frequent among PWH and varied considerably between age and risk groups.
