Pre-exposure Prophylaxis Use and Detected Sexually Transmitted Infections Among Men Who Have Sex With Men in the United States—National HIV Behavioral Surveillance, 5 US Cities, 2017

Abstract

The prevalence of extragenital STI was high for both MSM on PrEP and those not on PrEP in the past year. MSM on PrEP were more likely to have rectal chlamydia but not pharyngeal STIs or rectal gonorrhea. Our findings support regular STI testing at exposed anatomic sites as recommended for sexually active MSM, including those on PrEP.
