【摘要】：目的了解河南省淮阳丘陵生态区人体肠道寄生虫病流行现状。方法按照全国第三次人体重点寄生虫病调查方案及河南省的调查方案,在生态区的基础上,结合经济和地理条件进行分层整群抽样。对调查点常驻居民采用改良加藤法和碘液涂片法分别检查肠道蠕虫和原虫感染情况,3~6岁儿童用肛拭法检测蛲虫感染。结果河南省淮阳丘陵生态区抽中9个县,26个调查点,共调查6 710人,其中528名3~6岁儿童接受了蛲虫肛拭检查。共查出肠道寄生虫11种,总感染率1.65%,其中蠕虫5种,感染率1.07%;原虫6种,感染率0.61%;儿童肛拭阳性率3.79%。混合感染占0.10%,均为2虫种混合感染。主要肠道寄生虫为蛔虫0.31%、人芽囊原虫0.28%和钩虫0.27%。儿童肛拭蛲虫感染率3.79%。原虫在各年龄组均有感染,9岁及以下人群发现的寄生虫感染种类最多,以蛲虫为主。经驱虫人群肠道寄生虫和土源性线虫感染率均较未驱虫人群低。结论河南省淮阳丘陵生态区人体重点寄生虫感染率明显下降,应加强对学龄前儿童和学生的寄生虫病防治与监测工作。
[Abstract]:Objective to investigate the prevalence of intestinal parasitic diseases in the ecological region of Huaiyang hilly region in Henan Province. Methods according to the third national investigation scheme of human parasitic diseases and the investigation plan of Henan Province, the stratified cluster sampling was carried out on the basis of ecological area and combined with economic and geographical conditions. The intestinal helminth and protozoa infection were detected by modified Kato method and iodine smear method respectively, and Enterobius vermicularis infection was detected by anal swab method in children aged 3 to 6 years old. Results A total of 6 710 people were investigated in 9 counties and 26 investigation sites in Huaiyang hilly ecological area of Henan Province. 528 children aged 3 years old were examined by anal swab of Enterobius vermicularis. There were 11 kinds of intestinal parasites, the total infection rate was 1.65%, including 5 species of worms, 6 species of protozoa, 0.61% of infection rate, and 3.79% of positive rate of anal swab in children. Mixed infection accounted for 0.10%, both of them were mixed infection of two species. The main intestinal parasites were Ascaris lumbricoides 0.31%, protozoa hominis 0.28% and hookworm 0.27%. The infection rate of Enterobius vermicularis in children was 3.79%. Protozoa infection was found in all age groups, and most parasites were found in the population aged 9 and below, mainly Enterobius vermicularis. The infection rates of intestinal parasites and soil-derived nematode were lower in the population with insect repellent than those without. Conclusion the infection rate of key parasites in Huaiyang hilly ecological area of Henan Province is obviously decreased. The prevention and control of parasitosis among preschool children and students should be strengthened.
