This study builds evidence on the importance of using safe drinking water during the nutritional treatment of children affected by Severe Acute Malnutrition (SAM). The following hypotheses will be tested: 1.The addition of safe drinking water to SAM treatment will reduce exposure to pathogens that cause diarrhoeal disease, thereby reducing diarrhoea incidence among enrolled children. 2.Reductions in pathogen exposure and diarrhoeal disease will result in shorter recovery pe-riods for children with SAM. The study will evaluate the effectiveness of safe drinking water in reducing SAM treatment cost and duration and will provide recommendations for improving SAM treatment protocols.
