This paper critically reviews the existing research on the cost-effective prevention and treatment of diarrheal diseases, and identifies research priorities in this area aimed at finding ways to reduce the diarrheal disease burden. In contrast to the empirical knowledge base that exists for...

Randomized controlled trials (RCTs) of water treatment are typically powered to detect effects on caregiver-reported diarrhea but not child mortality, as detecting mortality effects requires prohibitively large sample sizes. Consequently, water treatment is seldom included in lists of...
