Instruction in behavior modification can significantly alter soil-transmitted helminth (STH) re-infection following therapeutic de-worming.

Five elementary ("prototypic") schools located in five districts in central Java were selected and the children examined for helminth infections (Ascaris, Trichuris, hookworm). They were de-wormed with a course of mebendazole and provided with 6-7 months of "behavioral remediation instruction" (BRI). In other ("control") schools, children were treated with mebendazole but were not provided BRI.

Behavioral and hygienic characteristics of primary schoolchildren which can be modified to reduce the prevalence of geohelminth infections: a study in central Java, Indonesia.

Five schools in central Java that enroll more than 500 students in grades one through six were chosen for a study of the prevalence of parasitic geohelminths and selected protozoan infections. The schools are located in regions that differ in geological features, density of vegetation and cultural and economic attributes. The prevalence of soil-transmitted helminths among children in the five schools ranged from 8.
