Effect of WHO-yaws Elimination Strategy in Lihir Island, Papua New Guinea

Summary

The trial that the investigators are proposing is a pilot study to determine the effect of the new WHO-yaws eradication strategy in Lihir Island (population 18,000), Papua New Guinea. 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.
