This study will be conducted as a randomized, double-blind, placebo-controlled trial to compare routine antibiotic prescription vs. no routine antibiotic prescription in the management of uncomplicated cases of severe acute malnutrition treated in the community in terms of nutritional recovery. The investigators hypothesize that there will be no significant difference in terms of the risk of nutritional recovery among children uncomplicated cases of severe acute malnutrition treated in the community that receive routine antibiotic prescription and those who receive no routine antibiotic prescription.
