Description
Scott D Nash and co-authors measure an eye disease, trachoma, and the infection behind it in a locality in Sudan, published in 2026. Trachoma remains endemic in Sudan. A baseline survey years earlier found a level of the key clinical sign that triggered mass drug administration with an antibiotic.
After three rounds of that program, an impact survey was run. Trained graders checked participants for clinical signs, and children were swabbed to test for the causative bacterium by DNA. The clinical sign stayed above the elimination threshold, and infection was still present, at a low level clustered in central communities with high sign levels. The authors argue that infection testing should be considered alongside clinical signs in trachoma programs, to better judge how endemic a place remains.
