The school teachers and community based volunteers will provide the drugs to both enrolled and non-enrolled school-aged children. Percentage coverage of school-aged children will be the outcome measure and compated between the school teachers and the community based volunteers. Stool and urine samples will be collected from a representative sample (916) of the children for laboratory analysis before the administration of the drugs for baseline data. Sample collection and laboratory analysis will be repeated 6 and 12 months after the first round of chemotherapy.
