Abstract: Objective To evaluate the effect of control interventions for intestinal nematodiasis in areas with low prevalence， so as to explore the effective measures for the control of intestinal nematode infections in Changzhou City，Jiangsu Province，Chi? na. Methods The residents in Wujin，Jintan，Tianning districts were selected as monitor subjects and the infections of intestinal nematodes were investigated with Kato?Katz technique or the transparent tape anal swab method. The results were analyzed statisti? cally and the cost?effectiveness was also analyzed. Results A total of 26 966 people were investigated and the total infection rate of intestinal nematodes was 0.37%（99/26 966） . The infection rates of the local residents and floating population were 0.31% （63/20 267）and 0.55%（37/6 699），respectively，and the former was lower the latter（P < 0.01）；the infection rates of urban res? idents and rural residents were 0.29%（44/15 328）and 0.47%（55/11 638）， respectively，and the former was lower than the latter （P < 0.05） . The 3 jurisdictions used different interventions，and the costs of 1% infection rate drop were 15.9 yuan/thousand peo? ple in Wujin District，1.9 yuan/thousand people in Jintan District，and 1.7 yuan/thousand people in Tianning District. The cost in Jintan was lower than that in Wujin，but the infection rate drop in Jintan was more than that in Wujin. Conclusion The floating population as well as the rural residents is still the focus and difficulty of the intestinal nematodiasis control. The deworming and health education are the main interventions in the key population.
