HIV Serostatus Disclosure Among Men Who Have Sex with Men in China in the Era of U=U and PrEP.

Given the recent evidence on "Undetectable = Untransmittable" (U=U) and pre-exposure prophylaxis (PrEP), the present study aimed to investigate HIV disclosure behaviors and their associations with sexual risk behaviors and U=U and PrEP awareness among men who have sex with men (MSM) in China. A cross-sectional survey was conducted among 689 MSM recruited through a gay-friendly non-governmental organization located in Chengdu, China in 2018-2019. Information was collected by a structured self-administrated questionnaire.
