Abstract
A model for school-based control of common intestinal helminths was developed and tested in Vkelet Elementary School in Bataan, Laguna, Philippines. Integrating health education with education programs, monitoring parasitologic parameters, and comparing the efficacy of once versus twice yearly mass treatments were the key components. Mebendazole (Antiox) 500 mg flavored tablets were administered to schoolchildren with parental consent following a treatment schedule determined by randomization. Parasitological assessment and monitoring were conducted among third-grade pupils considered the indicator group. Stool specimens were collected and processed using the Kato-Katz method, which allowed qualitative and quantitative diagnosis in terms of parasite species and egg counts, respectively. Parasitologic parameters were monitored on days 0, 14, 30, 60, and 194, 360, and 374. There were significant reductions in infection rates and intensities of infection post-treatment. Twice-yearly deworming was shown to be superior to once-yearly treatment. Continuation of periodic mass treatments with mebendazole, initially twice yearly with monitoring of parasitologic and nutritional progress, as well as school performance, is strongly recommended for the school. Further application of the results of this and other similar studies is recommended.
