It kills a child under age 5 every minute on average. Diarrheal disease, the second leading cause of death for children globally, could become even more difficult to control as poor urban areas with limited clean water access expand. An international team of researchers including Stanford epidemiologist Stephen Luby finds reason for hope in a low-cost water treatment device that reduces rates of diarrhea in children, provides good-tasting water and avoids the need for in-home treatment – improvements over other purification strategies that could significantly increase uptake. Their results were published Aug. 8 in The Lancet Global Health.
