为了解人群藐小棘隙吸虫感染的季节分布和影响因素以及年度感染情况，于１９９５年在安徽和县陈桥村选择１所小学进行纵向观察研究。结果表明，在小学生中藐小棘隙吸虫感染呈明显季节性，秋季（９～１０月份）是感染的高峰季节，生饮含有该虫尾蚴的池塘水是造成季节性感染的主要原因。各月份藐小棘隙吸虫感染率与饮生水率、饮水频次和饮生水量，经相关分析均有显著意义（ｒ分别为０．９６０、０．８３４和０．８９６，Ｐ＜０．０５）。同时调查表明小学生藐小棘隙吸虫年度感染严重，感染率高达３１．８７％，是该地区影响青少年健康的常见寄生虫病。
In order to understand the seasonal distribution and influential factors of the population of Echinococcosis and the annual infection, a longitudinal study was conducted in 1995 at a primary school in Chenqiao Village, Anhui Province. The results showed that there was a seasonal seasonal infection in primary pupils, autumn (September to October) was the peak season of infection, and raw water containing the cercariae was the main cause of seasonal infection. In each month, the infection rate of Echinococcosis and the rate of drinking and drinking, the frequency of drinking and the amount of drinking and drinking were significant (r = 0.960, 0.834 and 0.896 respectively, P <0.05 ). In the meantime, investigations showed that the annual prevalence rate of primary spinovars was so high that the infection rate was as high as 31.87%. It is a common parasitic disease affecting the health of adolescents in the area.
