To understand the epidemic status of principal human parasitosis in the ecological region of Huaiyang hills of Henan Province.
According to the scheme of The 3rd National Survey of Principal Human Parasites made by National Institute of Parasitic Diseases, the survey was performed based on the ecological regions. The stratified cluster sampling was made combined with the economic and geographical conditions. The infections of intestinal helminths and protozoans in permanent residents were respectively detected by Kato-Kats technique and iodine solution. infection was detected by the cellophane swab method in children aged 3 to 6 years.
Totally 6 710 residents in 26 survey spots from 9 counties were detected, in which 528 children aged 3 to 6 years were detected for infection. Eleven kinds of parasites were found in this survey, including 5 species of helminthes and 6 species of protozoans. The infection rates of overall parasites, helminthes and protozoans were respectively 1.65%, 1.07% and 0.61%. The infection rate of in the children aged 3 to 6 years was 3.79%. Only 0.10 percent of the infections were co-infection, and all were infected by 2 kinds of parasites. The principal parasites in this district were (0.31%), (0.28%) and hookworm (0.27%). The infection rate among children was 3.79% by the cellophane swab method. The infections of protozoans were found in all age groups. In the group aged 9 years and below, the maximum kinds of parasites were found.
The infection rates of principal human parasites in Huaiyang hilly ecological region of Henan have decreased sharply, but more efforts still should be paid on the prevention and control of parasitosis in children.
了解河南省淮阳丘陵生态区主要人体寄生虫病的流行状况。
按照中国疾病预防控制中心寄生虫病预防控制所制定的第三次全国人体重要寄生虫病现状调查方案，以生态区为基础开展调查。结合经济和地理条件进行分层整群抽样。采用改良加藤厚涂片法和碘液涂片法分别检测常住人口肠道蠕虫和原虫感染情况。采用透明胶纸肛拭法检测3～6岁儿童蛲虫感染情况。
共调查9个县26个调查点的6710名居民，其中检测3～6岁儿童528名。本次调查发现11种寄生虫，其中蠕虫5种，原虫6种。总体寄生虫、蠕虫和原虫的感染率分别为1.65%、1.07%和0.61%。3～6岁儿童蛲虫感染率为3.79%。仅0.10%的感染者为混合感染，且均为两种寄生虫感染。该地区主要寄生虫为蛔虫（0.31%）、鞭虫（0.28%）和钩虫（0.27%）。采用透明胶纸肛拭法检测儿童蛲虫感染率为3.79%。各年龄组均发现原虫感染。9岁及以下组发现的寄生虫种类最多。
河南省淮阳丘陵生态区主要人体寄生虫感染率已大幅下降，但儿童寄生虫病的防治仍需进一步加强。
