三峡工程运行后鄱阳湖区居民接触疫水特征分析

目的 目的 掌握三峡工程运行后鄱阳湖血吸虫病流行区居民疫水接触特征， 为制定有针对性的防治对策提供参考依据。方法 方法 选择鄱阳湖2个湖沼型血吸虫病疫区村居民作为观察对象， 以问卷调查方法调查居民接触疫水情况。结果 结果鄱阳湖区居民接触疫水比例及频率较高， 平均疫水接触率为69.77%， 98.96%的疫水接触行为发生在春、 夏、 秋3个季节。成年男性以生产性接触疫水为主， 主要接触方式为捕鱼和游泳/玩耍； 成年女性以生活和生产性接触疫水并重， 主要接触方式为洗衣和捕鱼； 学生以生活和娱乐性接触疫水为主， 主要接触方式为游泳/玩耍和洗手， 3类人群疫水接触率分别为73.33%、 71.63%和61.87%。居民接触疫水频率＞1次/周、 1次/周～1次/月和< 1次/月的构成比分别为62.61%、 23.74%和13.66%。结论 结论 鄱阳湖区居民接触疫水主要时间段为春、 夏和秋季， 主要接触方式为捕鱼， 种田和打草等生产性接触疫水已由过去的主要方式转变为现在的次要方式

Analysis of characteristics of schistosome cercarial infested water contacts of residents in Poyang Lake endemic areas after operation of Three Gorges Project

Objective To understand the characteristics of schistosome cercarial infested water contact of residents in Poyang Lake endemic areas after the operation of Three Gorges Project,so as to provide the evidence for formulating a well-directed con-trol strategy. Methods The residents in two villages in schistosomiasis endemic areas were selected and surveyed for their activi-ties of infested water contacts by questionnaire. Results The proportion and frequency of infested water contacts of residents in Poyang Lake region were high and the average rate of infested water contacts was 69.77%,and 98.96%of infested water contacts occurred in spring,summer and autumn. The main ways of infested water contacts were fishing/swimming/playing for adult men, washing clothes/fishing for adult women,and swimming/playing for school children,respectively. The rates of infested water con-tacts were 73.33%,71.63%and 61.87%in adult men,women and school children,respectively. The frequencies of infested water contacts＆gt;1 time/week,1 time/week-1 time/month,and＆lt;1 time/month were 62.61%,23.74%and 13.66%respectively. Conclu-sions The infested water contacts mainly occurs in spring,summer and autumn,and the main way of infested water contacts was fishing.
