【摘要】 本文以前瞻性定群研究，报道了饮水与藐小棘隙吸虫感染的关系。结果表明：１．陈桥洲居民藐小棘隙吸虫年感染率为１１．２３％；２．饮用塘水和混饮江、塘水者感染藐小棘隙吸虫的相对危险度（ＲＲ）分别是饮江水者的３．７２倍和４．２８倍；３．饮生水人群的ＲＲ是４非饮生水者的８．１２倍，且分层分析后上述关系仍然成立；４．感染率与饮生水量呈剂量反应关系；５．其它寄生虫未见上述联系；６．当地人群特异危险度（ＰＡＲ）及特异危险度百分比（ＰＡＲ％）分别为９．４３％和８３．９７％。结果提示生饮塘水为当地居民感染藐小棘隙吸虫的主要途径。更多还原

【Abstract】 This paper reports the relationship between the drinking water and Echinochasmusliliputanus (EL )infection by using the method of prospective cohort study. The results as fol-lows :1.the morbidity rate of human infected with EL was 11. 23%in Chenqiaozhou Village Hex-ian County Anhui Province.2. Relative risk(RR) of people infected with EL were 2.72 and 3. 28times higher in the population drinking water from pond and from both pond and the YangtseRiver than that only from the Yangtse River respectively..RR was 7.12 times higher in thepopulation drinking raw water than that in the population not drinking raw water ,this associa-tion persisted even after stratified analysis. Dose response relationship was found between ELinfection and the amount of drinking raw water.5.These relationship was not found at the otherparasitic diseasesin this village.6. for inhabitants in the village PAR was 9.43%and PAR%was 83.97%.The results suggested that in this village the major mode of transmission of EL wasdrinking raw water from pond.更多还原
