Mali hospital study tracks hidden COVID-19 cases
NCT ID NCT04710316
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how COVID-19 spread among patients and healthcare workers in four hospitals in Bamako, Mali. Researchers used molecular tests to find active infections and blood tests to check for past infections and immunity. The goal was to understand infection rates, including in people without symptoms, and to see if point-of-care testing could work in Mali.
