Yaws Prevalence, Lessons from the Field and the Way Forward towards Yaws Eradication in Ghana

International Scholarly Research Notices, Volume 2014, Issue 1, 2014., 2014
Despite past WHO/UNICEF led global yaws eradication efforts, the disease seems to persist. The true burden is however not known for comprehensive action. Ghana’s data showed significant increase in notified cases since the 1970s. Recognizing limitations in routine data, we carried out a yaws treatment survey in 2008 in three purposively selected ...
