On multivariate analysis, self-reporting as transgender women (adjusted odds ratio [AOR] 7.41, 95% CI 1.59\u201034.53) and men who have sex with men (AOR 2.59, 95% CI 1.02\u20106.56) compared to heterosexual men, and students compared to office workers or employers (AOR 3.76, 95% CI 1.25\u201011.35) were associated with RITA-CS-recent infection.
