First seen Jun 27, 2026 · Last updated Aug 05, 2026 · Updated 2 times
Summary
This trial tests whether actively searching for leprosy cases in communities finds more people with the disease than waiting for them to come to clinics. Researchers will raise awareness, train healthcare workers, and use questionnaires and rapid tests in high-risk areas. About 1,925 people will take part across multiple municipalities in Brazil.
