4、destroycholeraonceandforall.在英国医生约翰斯诺向人们展示如何战胜霍乱之前，霍乱曾是世界上最令人恐惧的疾病之一。它可导致严重腹泻、脱水甚至死亡。十九世纪初，崔乱暴发，肆虐欧洲，数百万人丧命。由于当时无人知道如何预防或治疗霍乱，年轻的约翰斯诺医生很沮丧。后来，他成了一位名医。甚至照料分娩的维多利亚女王。然而，他始终没有放弃彻底根除霍乱的愿望Ingeneral,doctorsinthosedayshadtwocontradictorytheoriestoexplainhowcholeraspread.Onetheorywas

10、oughthisintervention,thediseasewasstoppedinitstracks斯诺首先在地图上标出所有死者住所的确切位置。宽街水泵附近有多例死亡(尤其是16号、37号、38号及40号住宅)，但是有些住户(如宽街20号和21号以及剑桥街8号和9号)却无人死亡。这些幸存者在剑桥街7号的酒吧工作，酒吧为他们提供免费啤酒，因此没有喝水泵抽上来的水。斯诺怀疑水泵就是罪魁祸首。此外，在伦敦的另一个区域，一名妇女和她的女儿从宽街搬来后死于霍乱。该妇女似乎非常喜欢从水泵抽上来的水，每天都让人从那里打水运到家里来。有了这个证据，约翰斯诺就能够宣布水泵抽上来的水携带霍乱

12、waspollutedbyrawwaste.Thepeoplewhodrankthiswaterweremuchmorelikelytogetcholerathanthosewhodrankpureorboiledwater事情的真相是宽街水泵抽上来的水被废弃物污染了。此外，斯诺之后还证明了另外几起霍乱病例与伦敦多家饮用水公司有关。有些公司出售的水取自被未处理的废弃物污染的泰晤士河。与饮用纯浄水或开水的人相比，饮用被污染的水的人更容易染上霍乱。ThroughSnowstirelessefforts,watercompaniesb
