Assessing the Impact of Sanitation on Disease

In Tropical Medicine and International Health, researchers from 13 different research institutions, including the Water Institute, conducted a systematic review of studies published between 1970 and 2013 in order to assess the impact of inadequate water and sanitation on diarrhoeal disease in low and middle-income settings. Overall, improvements in drinking water and sanitation were associated with decreased risks of diarrhea but there were notable differences in illness reduction according to the type of improvements made.
