What this research studies
The research team will work with community members to adapt simple reminders, prompts, and incentives that address common reasons people skip retesting. They will prototype these nudges with end users and local partners to make sure they fit the local context. Then participants at multiple clinic sites in sub-Saharan Africa will be randomly offered different nudges so researchers can see which approaches lead to more retesting. The study tracks return testing, linkage to care, and uptake of prevention like PrEP to identify practical strategies clinics can use.
Who could benefit from this research
Good fit: Adults (age 21+) at increased risk of HIV—such as people with recent exposures, partners with HIV, or those eligible for PrEP—who live near participating clinics in sub-Saharan Africa.
Not a fit: Children and adolescents under 21, people not at increased risk, or those already on continuous testing schedules or fully engaged in care may not receive direct benefit from this project.
Why it matters
Potential benefit: If successful, this could lead to more timely HIV diagnoses and increase linkage to treatment or prevention services like PrEP.
How similar studies have performed: Related low-cost behavioral 'nudge' approaches have improved health behaviors in other areas, but large-scale evidence specifically showing increased HIV retesting is still limited.
