目的了解金湖县人体寄生虫病流行状况,分析流行规律和影响因素,探讨今后防治对策。方法分别于1989、1999年和2015年在金湖县随机抽取调查点,对当地常住人口开展人体寄生虫病分布调查。采用改良加藤厚涂片法(Kato-Katz法)检查土源性线虫、华支睾吸虫、姜片吸虫感染情况,采用透明胶纸肛拭法检查儿童蛲虫卵,采用碘液涂片法和生理盐水涂片法检查肠道原虫包囊或滋养体。结果 1989、1999年和2015年金湖县人体寄生虫总感染率分别为62.57%、9.32%和0.49%,2015年感染率较1999年下降了94.74%,较1989年下降了99.22%;检测到的人体寄生虫虫种分别为14、10种和4种。感染度均以轻度感染为主,其中2015年均为轻度感染。感染者均以感染单一虫种为主,1989年混合感染4种虫种者占0.72%,感染3种者占7.02%;1999年和2015年未发现混合感染3种虫种及以上者。性别分布仅1989年女性感染率高于男性,差异有统计学意义(χ2=18.01,P<0.01)。结论金湖县人体寄生虫感染率持续下降至较低水平,今后需做好监测工作,巩固防治成果。
Objective To understand the prevalence of human parasitic diseases in Jinhu County, analyze the epidemic rules and influencing factors, and discuss the future prevention and treatment measures. Methods The investigation points were randomly selected in Jinhu County in 1989, 1999 and 2015 respectively to investigate the distribution of human parasites in the local population. The Kato-Katz method was used to check the infection of soil-borne nematodes, Clonorchis sinensis and Grifola, and the eggs were screened by the transparent adhesive tape anal swab method. The iodine smear method and the physiology Saline smear method for detecting intestinal protozoa cysts or trophozoites. Results The total infection rate of human parasites in Jinhu was 62.57%, 9.32% and 0.49% in 1989, 1999 and 2015 respectively. The infection rate in 2015 was 94.74% lower than that in 1999 and 99.22% lower than that in 1989. The detected Human parasitic worms were 14,10 species and 4 species. Infection were mainly mild infection, of which 2015 were mild infections. Infected persons were infected with a single species of insects mainly in 1989 mixed infection of four kinds of worms accounted for 0.72%, three kinds of infections accounted for 7.22%; in 1999 and 2015 did not find mixed infection of three kinds of insects and above. Gender distribution In 1989, the infection rate of women was higher than that of men only (χ2 = 18.01, P <0.01). Conclusion The infection rate of human parasites in Jinhu County continued to drop to a low level. Monitoring work should be done in the future to consolidate the results of prevention and treatment.
