To assess the effectiveness and cost-effectiveness of three different point-of-use water treatment technologies (a flocculent-disinfectant, a disinfectant, and water filters) in reducing the incidence of child diarrhea and length of stay in the Community-based Management of Acute Malnutrition (CMAM) program.  Based on the well-documented cyclical nature of waterborne disease and undernutrition, we hypothesize that the addition of safe drinking water will reduce the amount of time for children impacted by severe acute malnutrition to recover, which will in turn increase the cost-effectiveness of CMAM programs by reducing the quantity of Ready-to-Use Therapeutic Foods (RUTFs) that are required by each child.
