重庆市江津区土源线虫病感染调查分析

Epidemiology of soil-transmitted nematode infections in Jiangjin district of Chongqing municipality

目的:了解江津区土源线虫的感染情况和态势,为制定防治对策提供科学依据。方法:按照卫生部《土源性线虫病防治技术方案(2010年版)》采样和检测,以江津先锋镇为中心,抽取东南西北中5个方位5个居民点,每个居民点采样500份,样品采用改良加藤厚涂片检测各种蠕虫卵。结果:以病原学检查方法检测5个居民点2 465人,检出蛔虫、钩虫2种,未检出鞭虫。钩虫感染率最高达9.57%,蛔虫感染率仅0.77%。土源线虫感染率为10.14%。结论:江津区农村社区居民感染率高于城镇,蔬菜基地感染率最高,土源线虫感染率呈下降趋势,年龄偏大、文化程度低、从事农业生产的人群仍是感染土源线虫的重点人群。

Objective：To analyze the epidemic status of soil-transmitted nematode in Jiangjin District with the purpose of providing scientific basis for making measurements for prevention and treatment.Methods：5 settlements of different life styles and farming methods were extracted from 4 towns separately located in east,west,north,and south by convenience sampling approach with Xianfeng Town as the center.500 samples were taken from every settlement,and the samples were tested in accordance with national soil-transmitted nematodes test program.Results：2645 people from 5 settlements were tested in the way of pathologic examination.Only roundworm and hookworm were found while whipworm was not.The highest hookworm infection rate was up to 9.57%,and the roundworm infection rate was only 0.77%.Soil-transmitted nematode infection rate was 10.1%.Rural areas had a higher infection rate than urban and the vegetable base had the highest.Conclusion：Infection rate of rural communities is higher than urban residents,with vegetable base the highest infection rate.Common intestinal parasite infection rate declines.The population of older age,with low education level,and engaged in agricultural production are still the key group of soil-transmitted nematode infection.
