Burden of Disease from Inadequate Water, Sanitation and Hygiene in Low- and Middle-Income Settings: a Retrospective Analysis of Data from 145 Countries.

This study by Prüss-Üstün et al. (2014) and published in Tropical Medicine and International Health estimates the burden of diarrhoeal diseases from exposure to inadequate WASH in low- and middle-income settings. Global exposure data were estimated for the year 2012, and risk estimates were taken from the most recent systematic analyses. In 2012, 842 000 diarrhoea deaths are estimated to be caused by inadequate drinking water, poor sanitation and hygiene, which amounts to 1.5% of the total disease burden and 58% of diarrhoeal diseases.
