Improving Nutrition Outcomes with Better Water, Sanitation and Hygiene

This publication, jointly prepared by WHO, the United Nations Children's Fund (UNICEF) and the United States Agency for International Development (USAID), summarizes the current evidence on the benefits of WASH (water, sanitation and hygiene) for improving nutrition outcomes and describes how WASH interventions can be integrated into nutrition programs. It provides practical suggestions, targeted at nutrition program managers and implementers, on both "what" WASH interventions should be included in nutrition programs and "how" to include them. It also seeks to help the WASH community to better understand their role, both as providers of technical expertise in WASH interventions and in prioritizing longer-term improvements to WASH infrastructure in areas where under-nutrition is a concern.
