Treponematosis eradication, with special reference to yaws eradication in Haiti.

This paper outlines the general administrative and therapeutic principles governing yaws eradication campaigns, with particular reference to the operational problems encountered in Haiti. The ways in which those problems were solved are described in the course of a relatively detailed account of the yaws eradication programme which began in that country in 1950 and which has now reached the end of the "mopping-up" phase. The author points out that lessons learnt in this mass treatment campaign can usefully be applied to eradication programmes against other diseases.
