中文摘要：

目的了解云南省洱源县人体重要寄生虫感染的现状和特点，为制定防治对策提供科学依据。方法采用随机抽样法在全县抽取35个自然村为调查点，每个调查点随机抽取35户居民作为调查对象。对土源性线虫、绦虫和血吸虫感染等采用病原学检查，旋毛虫病、猪囊尾蚴病和血吸虫病采用血清学检查。结果寄生虫总感染率为23．34%（772／3308），其中坝区与山区人群感染率分别为19．55％（333／1703）和27．35％（439／1605），两者差异有统计学意义（P〈0．01）。共查出7种寄生虫，感染率分别为蛔虫15．75％、钩虫0．33％、鞭虫1．87％、绦虫（包括链状带绦虫和微小膜壳绦虫）3．72％、蛲虫0．18％、血吸虫1．51％。混合感染人数占总感染人数的8．94％（69／772）。旋毛虫病、猪囊尾蚴病和血吸虫病的血清阳性率分别为57．30％（2103／3670）、18．20％（668／3670）、21．16％（958／3662）。本次调查结果寄生虫总感染率低于2004年全省调查的28．86％，而高于全国的19．56％。结论洱源县山区人群的人体重要寄生虫感染率明显高于坝区。感染虫种以蛔虫为主，其次为绦虫。绦虫病、猪囊尾蚴病、旋毛虫病和血吸虫病为今后该县寄生虫病防治工作的重点。

英文摘要：

Objective To understand the present status of human parasitic infections and their characteristics in Eryuan County of Yunnan Province in order to provide scientific basis for making the measures of parasitic diseases control. Methods A total sampled population of 3 308 from 35 selected spots in Eryuan County by random sampling were investigated. Parasitological examinations were conducted for the infections of soil-transmitted nematodes, cestodes and Schistosoma japonicum with Kato Katz technique and miraciduim hatching method.. Serological tests were applied for trichinosis, cystieercosis and schistosomiasis. Results The total infection rate of parasites was 23.34%. The infection rates of human parasites in plateau areas and in mountain areas were 19.55% and 27.35%, respectively. There was a significant difference （P〈0.01）. Seven kinds of parasites were found, in which the infection rate of Ascaris was 15.75%, hookworm 0. 33%, Trichuris 1.87%, Cestode （including Taenia solium and Hymenolepis diminuta） 3.72 %, Enterobius 0. 18%, Schistosoma japonicum 1.51%. The rate of persons infected with 2 kinds of worms was 8.94% in total infected people. The positive rates of serological tests for trichinosis, cysticercosis, and schistosomiasis were 57.30%（2 103/3 670）, 18. 20%（668/3 670）and 26.16%（958/3 662）, respectively. The total parasite infection rate of this investigation was 23.34%, less than 28. 86M,that of the investigation of the whole province in 2004, but higher than 19.56%, that of the national investigation. Conclusions The population infection rate in mountain areas is significantly higher than that in plateau areas. The main parasite is Ascaris, the second Cestode. The prevention and control of cestodiasis, trichinosis, cysticereosis and schistosomiasis will he the main target.
