ABSTRACT
With the assistance of WHO and the National Institute of Malariology, Parasitology and Entomology, the Helminth Control Project for primary school children has effectively been conducted during the years of 2002 -2004 in Phu Loc distric, Thua Thien - Hue province. The knowledge and awareness of children and their parents on the control and prevention of the disease were found much improved after the health education took place. The helminth prevalence and the intensity of infection were considerably reduced after the periodical mass deworming campains with 6 month intervals. Mebendazole appeared to be highly effective against such intestinal helminths as Ascaris, Trichuris and hook worms. It is recommended to maintain the results of the project in Phu Loc district, to expand and apply this project model in other districs. Integration of helminth control with other health programs of hygiene and enviroment should also be encouraged
