NCT ID NCT06971367
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to find low-cost ways to encourage people at higher risk of HIV to get retested. Researchers will test several simple behavioral interventions, like phone messages, in 40,000 adults in Kenya and Uganda. The goal is to see which methods work best to increase repeat HIV testing and, if needed, start prevention medication (PrEP).
