The Impact of Water, Sanitation and Hygiene on Key Health and Social Outcomes: Review of Evidence

This evidence paper developed by SHARE and UNICEF looks at 10 areas identified collaboratively on which WASH can plausibly have a strong impact: diarrhoea, nutrition, complementary food hygiene, female psychosocial stress, violence, maternal and newborn health, menstrual hygiene management, school attendance, oral vaccine performance, and neglected tropical diseases. The paper highlights a number of points where evidence-based consensus has been established, or is emerging in these areas. While the paper has been tailored to support the development of the new UNICEF’s Strategy for WASH 2016-2030, it has broader relevance to the WASH sector as a whole.
