Yaws Prevalence in Guyana

Posted by Michael_Silverman on 13 Sep 2008 at 17:47 GMT

In the Americas, the situation is less clear. Yaws has been eliminated from most of the continent (e.g., [14]), but a survey conducted in 2000 in rural Guyana indicated a prevalence of skin yaws similar to that recorded in 1952 in Haiti, the country with the highest prevalence in the Western Hemisphere before the eradication campaign began [15]. On the other hand, surveys carried out in 2006 and 2007 in endemic yaws territory in Guyana demonstrated no active cases of the disease [10].

Please note that between the survey of 2000, and the repeat surveys of 2005/6, an aggressive Yaws eradication campaign was carried out in this region using targeted oral penicillin therapy [15]. This is the reason for the dramatic change in prevalence between the different time periods.
