Yaws in the Americas.

Until the middle of this century, yaws was a major public health problem in the Americas Region of the World Health Organization. All countries located between the tropics of Cancer and Capricorn reported cases of yaws. From 1950 to 1957, major programs for the eradication of yaws were implemented throughout the region, and yaws rapidly ceased to be a threat. As of 1983, sporadic cases continued to occur in limited geographic areas of Colombia, French Guyana, Guyana, and Suriname.
