Lassa Fever is endemic in certain parts of West Africa, and has a case fatality rate of 69%. The disease is transmitted via rodents, and whilst much research has gone into the treatment, limited information is available on it’s prevention. The DfID funded WASH Facility supported Tulane University and the Sierra Leone Ministry of Health & Sanitation to undertake a pilot on prevention, predominantly looking at measures that can be integrated within rural water, sanitation and hygiene programmes.
