ABSTRACT: Infection with soil-transmitted helminths (STH) is still prevailing in developing countries including Myanmar especially in primary school children. Worm infestation is one of the priority diseases of National Health Plan in Myanmar. An intervention study was carried out among primary school children in three selected townships (Hlinethaya, South Dagon and North Dagon) of Yangon Region in 2013. The objective of this study was to assess the effectiveness of deworming and health education on STH prevalence among selected primary school children. A total of 1443 stool samples were examined using Kato-Katz thick smear technique before and after giving Albendazole (400 mg) drug according to school regular deworming programme. At the same time, health education regarding prevention of STH was given to the students and their parents or guardians. During baseline survey, helminths were detected in 32.3%, 18% and 10.6% of the students in Hlinethaya, South Dagon and North Dagon townships, respectively while in the second time survey (which was carried out 6 months after baseline survey), they were detected in 32.5%, 10.6% and 9.6%, respectively. Trichuris trichiura was found to be the most prevalent helminth in both surveys. These findings indicated that preventive chemotherapy together with health education play an important role in reduction of the prevalence of STH in two out of three townships. The prevalence of STH in Hlinethaya Township was not reduced which might be due to several factors including reinfection of the helminths, migrant population, low socio-economic status and poor personal hygiene.
