New treatment policies were developed by WHO in 2012 to replace those of the 1950s. The recommended practice is to offer an initial MDA with azithromycin to the entire population, followed by resurveys every 6 months to detect and treat remaining cases.We will use serology surveys, clinical surveys and ulcer aetiology studies to measure the effect of mass azithromycin treatment on the community burden of yaws infection.","abstract_license":"ClinicalTrials.gov (U.S. National Library of Medicine), data processed 2026-10-29T09:00:05; modifications: selected fields only; whitespace normalized; brief summary truncated to 2,000 characters","license":"ClinicalTrials.gov terms (attribution, processing date, modifications noted)","is_open_access":true,"peer_reviewed":null,"categories":["Yaws"],"details":{"acronym":"YESA-13","status":"COMPLETED","phase":"PHASE3","study_type":"INTERVENTIONAL","enrollment":16000,"sponsor":"Lihir Medical Centre","conditions":["Yaws"],"interventions":["DRUG: Azithromycin"],"start_date":"2013-03-01","start_date_type":null,"primary_completion_date":"2017-05-01","has_results":false,"data_source":"ClinicalTrials.gov","data_processed":"2026-10-29T09:00:05","modifications":"selected fields only; whitespace normalized; brief summary truncated to 2,000 characters"},"provenance":"clinicaltrials","attribution":"Source: ClinicalTrials.gov (U.S. National Library of Medicine), data processed 2026-10-29T09:00:05; modifications: selected fields only; whitespace normalized; brief summary truncated to 2,000 characters.
