Objective To understand the prevalence and incidence of intestinal worms in primary and secondary school students. Methods The infection rate of roundworms was used as an index to investigate and analyze the intestinal worm infection among national students from 1992 to 1995. Results Ascaris infection rate was 22.52% for primary school students, 1 8.19% for junior high school students and 16.66% for high school students, showing a declining trend year by year. Rural students are higher than city students. Conclusion The implementation of the “National Program for Prevention and Control of Common Diseases” and the “Comprehensive Prevention and Control Plan for Common Diseases in Schools” have yielded fruitful results. Health education for rural students still needs to be strengthened to further narrow the gap between urban and rural areas.
