In several subgroups of South Africa, the percentage of HIV-positive individuals aware of their status falls well below the UNAIDS 90% target. This study examined the impact that home-based HIV testing services (HBHTS) had on knowledge of status in a hyperendemic area of South Africa.
We analysed data from the second cross-sectional HIV Incidence Provincial Surveillance System survey (2015/2016), a representative sample (n = 10,236) of individuals aged 15–49 years. Participants completed a questionnaire, provided blood samples for laboratory testing (used to estimate HIV prevalence), and were offered HBHTS. The proportion of people living with HIV (n = 3870) made aware of their status through HBHTS was measured, and factors associated with HBHTS uptake were identified.
Knowledge of HIV-positive status at the time of the survey was 62.9% among men and 73.4% among women. Through HBHTS, the percentage of HIV-positive men and women who knew their status rose to 74.2% and 80.5%, respectively. The largest impact was observed among youth (15–24 years). Knowledge of status increased from 36.6% to 59.3% and from 50.8% to 64.8% among young men and women, respectively. In addition, 51.4% of those who had previously never tested received their first test. Key reasons for declining HBHTS among undiagnosed HIV-positive individuals included fear and self-report of an HIV-negative status.
HBHTS was effective in increasing awareness of HIV-positive status, particularly among youth, men, and those who had never tested. HBHTS could have a marked impact on progress toward the UNAIDS 90-90-90 targets within these subgroups.
