Diarrheal diseases are a leading cause of death for children in the developing world, killing 760,000 children under the age of five each year, yet many cases of diarrhea could be prevented with good water quality and sanitation. IPA’s research in this area explores the effectiveness of new and existing approaches for improving on water quality, sanitation, and hygiene (WASH).

Poor sanitation leads to major diseases, increased public health expenditures, and causes diarrhea—a leading cause of mortality in children under five.

Regular handwashing with soap is one of the best ways to prevent diarrheal and respiratory disease, which are two of the primary causes of death among children worldwide.

Poor sanitation is estimated to cause 280,000 deaths per year worldwide, despite the existence of simple, effective solutions.
