First seen Jun 27, 2026 · Last updated Sep 17, 2026 · Updated 2 times
Summary
This study tests whether a video app that explains 'Undetectable = Untransmittable' (U=U) can help people with HIV stay on treatment and keep the virus under control. About 880 people from clinics in South Africa will use the app during counseling. The goal is to see if better understanding of U=U improves viral suppression and retention in care.
