Deworm the World Initiative

From EA Wiki

Deworm the World works with health ministries in both India and various African countries to launch school-based deworming programs. It helps them with planning and the training of teachers to distribute the treatments. It has been recommended by leading charity evaluator GiveWell, and described as a “best buy” in global health listed by the Jameel Poverty Action Lab at MIT. They can treat children for well under a dollar, and have a funding gap of several million.
