Abstract

Historical and ecologic evidence is reviewed in an effort to account for the origin and continued existence of a focus of human onchocerciasis at San Antonio on the Río Micay in western Colombia, the first such focus observed in that country. From a Spanish colonial document of the early 18th century, it can be established that some of the Negro slaves then working in placer gold-mining operations on the Río Micay had been brought there recently and that some bore surnames that can be identified with tribal areas of West Africa where onchocerciasis is now present. It is suggested that the absence of horses and cattle at San Antonio is a key factor in the persistence of the disease there, since the presumed vector, , has recently been shown to be highly zoophilic elsewhere in western Colombia.
