目的了解丰泽区人群重点寄生虫感染现状和流行趋势,为制定寄生虫病防治策略提供科学依据。方法按照分层整群随机抽样原则,抽取505人进行土源性寄生虫(蛔虫、钩虫、鞭虫、蛲虫)感染情况调查,采用改良加藤法检查寄生虫虫卵。同时随机抽取当地304名托幼儿童开展蛲虫感染率调查,采用透明玻璃纸肛拭法检查蛲虫卵。结果人群土源性寄生虫感染率为0.79%(4/505),均为单虫种感染。其中蛲虫感染率为0.59%(3/505),钩虫为0.20%(1/505)。男女感染率相似,60岁以上人群感染率较高,托幼儿童蛲虫感染率为4.93%(15/304),各年龄组间感染率无统计学意义差异,男童感染率高于女童。结论丰泽区人群重点寄生虫感染率呈下降趋势,得益于近年来全区经济的发展和城市化进程加快,但寄生虫病尚未根本控制,仍可以通过加大健康教育宣传力度,采用驱虫治疗为主的综合措施,将丰泽区重点寄生虫感染率控制在更低水平。同时坚持政府领导、部门配合和社会参与的工作机制,加强粪便管理和安全供水,改进环境卫生,减少感染,巩固和扩大防治成果。
Objective To understand the prevalence and epidemiological trend of the major parasitic infections in Fengze district and to provide a scientific basis for the development of prevention and treatment strategies of parasitic diseases. Methods In accordance with the principle of stratified cluster random sampling, 505 people were surveyed to investigate the infection of soil-borne parasites (roundworm, hookworm, whipworm and pinworm), and the parasitoid eggs were examined by modified Kato method. At the same time, randomly selected 304 local kindergartens and nurseries to carry out the investigation of pinworm infection rate, the use of transparent cellophane anal swab method test ovipositor eggs. Results The prevalence of soil-borne parasites in the population was 0.79% (4/505), all of which were single species infection. Incidence of pinworm infection was 0.59% (3/505) and hookworm was 0.20% (1/505). The prevalence of infection was similar between men and women, and the infection rate was higher in people over 60 years of age. The infection rate was 4.93% (15/304). The infection rate among all age groups was not statistically significant. The prevalence rate of boys was higher than that of girls. Conclusions The population infection rate of major parasites in Fengze District shows a declining trend. Thanks to the economic development and urbanization acceleration in the whole region in recent years, parasitic diseases have not been fundamentally controlled yet. Worm treatment-based comprehensive measures to control the key areas of Fengze parasitic infection at a lower level. At the same time, we should adhere to the working mechanism of government leadership, departmental cooperation and social participation, strengthen manure management and safe water supply, improve environmental sanitation, reduce infection, and consolidate and expand prevention and treatment results.
