Door-to-Door help may increase COVID testing in Hard-to-Reach communities
NCT ID NCT05606016
First seen Aug 26, 2026 · Last updated Aug 27, 2026 · Updated 1 time
Summary
This study tests whether community health workers can help increase COVID-19 testing among vulnerable adults. Participants receive either education and rapid antigen test kits or guidance on where to get tested. The goal is to see which approach leads to more people getting tested and using tests correctly.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Facilitated Self-Sampling Intervention (FSSI) and Testing Navigation Intervention (TNI) delivered by community health workers
- What this could lead to
- If effective, this approach could increase COVID-19 testing among vulnerable groups, helping to control spread and improve health equity.
- What could go wrong
- The study is early and focuses on a specific intervention; results may not apply broadly. Also, testing behavior can be influenced by many factors beyond the intervention.
