The USAID Neglected Tropical Disases (NTD) program has programs to eliminate and/or control NTDs in 24 countries. Even as NTDs are eliminated through mass drug administration, the reinfection of these diseases will remain a problem if behaviors and the environment remain unchanged. STH, schistosomiasis, and trachoma are all clearly linked to inadequate sanitation, contaminated food and water, and poor hygiene, providing an opportunity for water, sanitation, and hygiene (WASH) related approaches to help change behavior and the environment. It is unlikely that trachoma can be eliminated without face washing and improved environmental hygiene and the cycle of STH treatment and reinfection will likely persist until sanitation and hygiene practices and conditions are improved.
The USAID WASHplus activity conducted this desk review of WASH interventions to help eliminate and/or control STH, shistosomiasis, and trachoma.
