Background: Combination HIV prevention initiatives incorporate evidence-based, biomedical and behavioral interventions
appropriate and acceptable to specific populations, aiming to significantly reduce population-level HIV incidence.
Knowledge of HIV serostatus is key to linkages to HIV care and prevention. Household-based HIV counseling and testing
(HBCT) can achieve high HIV testing rates. We evaluated HBCT as a platform for delivery of combination HIV prevention
services in sub-Saharan Africa.
