Neglected tropical diseases (NTDs) blight the lives of a billion people worldwide and threaten the health of millions more. These ancient companions of poverty weaken impoverished populations, frustrate the achievement of health in the Millennium Development Goals and impede global public health outcomes. An evaluation of their significance to public health and economies has convinced governments, donors, the pharmaceutical industry and other agencies, including nongovernmental organizations, to invest in preventing and controlling this diverse group of diseases.

Preventive chemotherapy is one of the interventions deployed by the World Health Organization to combat at least five diseases – lymphatic filariasis, onchocerciasis, schistosomiasis, soil-transmitted helminthiases and trachoma – involves administering six medicines in seven different combinations, making it possible to treat more than one disease at a time. Preventive chemotherapy is one of the largest, most successful public health interventions in history, benefitting a billion people worldwide.
