  • WHO Report: Preventing Diarrhea Through Better Water, Sanitation, and Hygiene
    The World Health Organization released a report on the global burden of diarrheal disease showing that deaths of children under five years old was down from 1.5 million in 1990 to 622,000 in 2012. Of these, 361,000 could be prevented with improved water, sanitation, and hygiene. Achieving universal access is an essential first step. The findings are based, in part, on collaborative research undertaken by WHO, the Water Institute at the University of North Carolina at Chapel Hill, and 13 other institutions. In addition, raising the quality of service levels through Water Safety Plans, household water treatment and safe storage, and well-managed sanitation systems is expected to yield substantial additional improvements in health.
