Key Considerations for Assessing School Food Environments

Abstract

Preschool children, school-age children and women of reproductive age are considered particularly vulnerable to STH infections, and WHO recommends the periodic deworming treatment (i.e., preventive chemotherapy) for these at-risk groups in countries endemic for STH.The recommended frequency of preventive chemotherapy is once or twice per year according the STH prevalence in the population at baseline. School-based deworming programmes entail treatment delivered through existing education infrastructure, administered by teachers with support from the health system.
