Of HIV‐positive participants. Prior HIV diagnosis = (1) reporting having tested HIV positive previously to standard interview questions, (2) having tested HIV positive at home in a prior round, or (3) having an HIV‐1 RNA concentration <1000 copies/μL. All estimates were weighted to the CHDSS census population by age group, sex, and urban (Chókwè town) or rural (CHDSS villages) residence, and adjusted for within‐household correlation. Reported for sex and age groups with at least 50 HIV‐positive participants.
