[Effect of control interventions for intestinal nematodiasis in areas with low prevalence in Changzhou City]
1Department of Epidemiology and Biostatistics, School of Public Health, Nanjing Medical University, Nanjing 211166, China.
Objective:
To evaluate the effect of control interventions for intestinal nematodiasis in areas with low prevalence, so as to explorethe effective measures for the control of intestinal nematode infections in Changzhou City, Jiangsu Province, China.
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 statistically 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 residents 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 people 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.
