Yaws in the Philippines: A clinico-seroprevalence study of selected communities in Mindanao.

This study confirmed that the Philippines is endemic for yaws but at a low level in the schools surveyed. This is an under-estimation due to the limited sampling. The lack of proper disease surveillance after the eradication campaign in the 1960's has made yaws a forgotten disease and has led to its resurgence. Yaws surveillance is needed to determine the extent of yaws in the Philippines and to help develop a strategy to eradicate yaws by 2030.
