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.

Many thanks, Michael, for clarifying this aspect of yaws situation in Guyana. As underlined in the article, this further demonstrates that well planned local interventions can bring yaws under full control, thus permitting its subsequent eradication.
