A simple method for filtering water to reduce the incidence of cholera was tested in a field trial in Matlab, Bangladesh, and proved effective. A follow-up study was conducted 5 years later to determine whether the filtration method continued to be employed by villagers and its impact on the incidence of cholera. A total of 7,233 village women collecting water daily for their households in Bangladesh were selected from the same study population of the original field trial for interviewing. Analysis of the data showed that 31% of the women used a filter of which 60% used sari filters for household water. Results showed that sari filtration not only was accepted and sustained by the villagers and benefited them, including their neighbors not filtering water, in reducing the incidence of cholera, the latter being an unexpected benefit.
一种简单的水过滤方法，用于降低霍乱发病率，在孟加拉国的 Matlab 进行了实地试验，结果证明有效。5 年后进行了后续研究，以确定村民是否继续采用这种过滤方法，以及该方法对霍乱发病率的影响。从最初的实地试验的相同研究人群中，共选择了 7233 名每天为家庭采集水的孟加拉国农村妇女进行访谈。数据分析显示，31%的妇女使用了过滤器，其中 60%的妇女使用莎丽过滤器来过滤家庭用水。结果表明，莎丽过滤不仅被村民接受和维持，而且使他们受益，包括他们没有过滤水的邻居，降低了霍乱的发病率，这是一个意外的好处。
