目的 了解南京市浦口区肠道线虫病流行动态及影响因素,为制订防治对策和评价防治效果提供科学依据。方法 收集南京市浦口区2006年以来肠道线虫病监测、驱虫服药、改水改厕及健康教育等资料,分析南京市浦口区疫情特点及防治效果。采集人群粪便标本,肠道线虫病监测采用改良加藤厚涂片法(Kato-Katz法),蛲虫检测采用透明胶纸肛拭法,采用饱和硝酸钠漂浮法检测土壤蛔虫卵。结果 2006-2019年共采集浦口区居民9 859人粪便标本,查出肠道线虫病感染者40人,不同年度感染率在0.00%~2.04%之间;2006-2019年抽取小学生及学龄前儿童9 605人,其蛲虫感染者68人,不同年度感染率在0.00%~2.23%之间;截止2019年底,全区无害化卫生厕所覆盖率达100%,自来水普及率达100%;人群肠道线虫病健康知识掌握率为 97.12%。结论 南京市浦口区肠道线虫病已处于极低的流行水平,但局部地区传播环节仍然存在,应继续开展监测工作。

Objective To understand the epidemic dynamics and influencing factors of intestinal nematodiasis in Pukou District of Nanjing City,and to provide scientific basis for formulating control strategies and evaluating control effects. Methods Data of intestinal nematodiasis surveillance,anthelmintic medication,improvement of water and toilet and health education were collected in Pukou District of Nanjing city since 2006.Stool samples were collected.Kato Katz method was used to monitor intestinal nem atodiasis.Transparent tape anal swab method was used to detect Enterobius vermicularis.Saturated sodium nitrate floating method was used to detect soil Ascaris eggs. Results A total of 9 859 fecal samples were collected from Pukou District from 2006 to 2019,and 40 cases of intestinal nematodiasis were found,the infection rate in different years was between 0.00% and 2.04%.From 2006 to 2019,9 605 pupils and preschool children were selected,68 of whom were infected with Enterobius vermicularis,and the infection rate in different years was between 0.00% and 2.23%.By the end of 2019,the coverage rate of harmless sanitary toilets in the whole district reached 100%,the penetration rate of tap water reached 100%.The knowledge mastery rate of intestinal nematode disease control is 97.12%. Conclusion The prevalence of intestinal nematodiasis in Pukou District of Nanjing city is at a very low level,but the transmission link still exists in some areas.
