摘要
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 epidemiological situation of human parasitic diseases in Jinhu County,so as to provide the evidence for formulating further control strategy. Methods The investigated local residents were sampled by the random cluster sampling method in 1989,1999 and 2015. The infections of intestinal helminthes were detected by KatoKatz technique,the eggs of Enterubius vermicularis were examined by cellophane anal swab for children,the intestinal protozoa were examined by the saline smear and iodine staining methods. Results The total rates of parasitic infections were 62.57%,9.32%and 0.49%in 1989,1999 and 2015,respectively. Compared to those in 1989 and in 1999,the infection rate in 2015 was decreased by 99.22%and 94.74%,respectively. The numbers of detected parasite species were 14,10 and 4 in 1989,1999 and 2015,respectively. The intensities of infections were mainly mild in three investigations,and the intensities of all the infections in 2015 were mild. The species of infected parasites were mainly single,however,multiple infections were observed in 1989,including 4 parasite species（0.72%）and 3 parasite species（7.02%）. Only in 1989,the difference between sexes was significant and the infection rate of the female was higher than that of the male（χ2=18.01,P〈0.01）. Conclusions The infection rates of human parasites are decreased gradually and stabilized at the low level in Jinhu County. However,the surveillance work still should be strengthened to consolidate the achievement.
