Positivity among those screened was syphilis, 7.8% (n = 18\/230); gonorrhea, 5.0% urogenital (10\/201), 11.1% rectal (18\/162), and 7.5% oropharyngeal (15\/201); chlamydia, 5.0% urogenital (10\/201), 11.7% rectal (19\/162), and 1.5% oropharyngeal (3\/201). Reported anal and oral sex (vs neither) was independently associated with STI screening (aPR, 2.11; 1.05\u20134.27) at PrEP initiation. At biannual PrEP-care visits, STI screening was lower and syphilis and rectal gonorrhea\/chlamydia positivity was higher.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Observed STI screening levels and disease burden suggest the effectiveness of STI screening in PrEP care for STI prevention may be limited.
