HIV status disclosure by Nigerian men who have sex with men and transgender women living with HIV: a cross-sectional analysis at enrollment into an observational cohort.

HIV status disclosure to sexual partners was uncommon among Nigerian MSM and TGW living with HIV but was associated with improved HIV care outcomes. Disclosure was not associated with substantially increased experiences of stigma. Strategies to encourage HIV status disclosure may improve HIV management outcomes in these highly-marginalized populations with a high burden of HIV infection.
