目的了解南通市农村居民肠道寄生虫病感染情况,为今后制定防治策略和措施提供科学依据。方法采用改良加藤氏厚涂片法检查农村居民肠道线虫卵感染情况;采用透明胶纸法检查农村幼儿园学龄前儿童和小学1～2年级学生蛲虫卵感染情况。结果 2003～2012年的10年间,我市农村居民肠道线虫病总感染率为1.93%,其中钩虫、蛔虫和鞭虫总感染率分别为0.97%、0.72%和0.24%。人群的总感染率和各单虫感染率均呈现逐年下降趋势;农村幼儿园学龄前儿童和小学低年级学生蛲虫病总感染率为1.87%。结论大规模人群集体驱虫服药是农村居民肠道线虫病感染率下降的主要措施;另加强室教活动,减少类便接触也是农村居民肠道线虫病感染率下降的另一主要因素。
Objective To understand the status of intestinal parasitic infection among rural residents in Nantong and to provide scientific evidence for future prevention and treatment strategies and measures. Methods The infection of gut nematode eggs of rural residents was examined by modified Kato’s thick smear method. The infection of ovipositor eggs of preschool children and primary and secondary schoolchildren in primary and secondary schools in rural kindergarten was examined by the method of clear tape. Results In the 10 years from 2003 to 2012, the overall infection rate of gut nematodes in rural areas was 1.93%. The total infection rates of hookworm, roundworm and whipworm were 0.97%, 0.72% and 0.24% respectively. The total infection rate of the population and the infection rate of each single organism showed a declining trend year by year. The total infection rate of enterobiasis in preschool children and primary school students in rural kindergartens was 1.87%. Conclusion Large-scale population de-worming medication is the main measure to reduce the infection rate of gut nematodes among rural residents. Another important factor is to reduce the infection rate of gut nematode among rural residents.
