约翰·斯洛击败“霍乱王”
JOHH SHOW DEFEATS “KING CHOLERA”
John Snow was a famous doctor in London - so expert, indeed, that he attended Queen Victoria as her personal physician. But he became inspired when he thought about helping ordinary people exposed to cholera. This was the deadly disease of its day. Neither its cause nor its cure was understood. So many thousands of terrified people died every time there was an outbreak. John Snow wanted to face the challenge and solve this problem. He knew that cholera would never be controlled until its cause was found.
约翰·斯洛是伦敦一位著名的医生——他的确医术精湛，因而成为照料维多利亚女王的私人医生。但他一想到要帮助那些得了霍乱的普通百姓时，他就感到很振奋。霍乱在当时是最致命的疾病，人们既不知道它的病源，也不了解它的治疗方法。每次霍乱暴发时，就有大批惊恐的老百姓死去。约翰·斯洛想面对这个挑战，解决这个问题。他知道，在找到病源之前，霍乱疫情是无法控制的。
He became interested in two theories that possibly explained how cholera killed people. The first suggested that cholera multiplied in the air. A cloud of dangerous gas floated around until it found its victims. The second suggested that people absorbed this disease into their bodies with their meals. From the stomach the disease quickly attacked the body and soon the affected person died.
中繁殖着，像一股危险的气体到处漂浮，直到找到病毒的受害者为止。第二种看法是人们在吃饭的时候把这种病毒引入体内的。病从胃里发作而迅速殃及全身，患者就会很快地死去。
John Snow suspected that the second theory was correct but he needed evidence. So when another outbreak hit London in 1854, he was ready to begin his enquiry. As the disease spread quickly through poor neighbourhoods, he began to gather information. In two particular streets, the cholera outbreak was so severe that more than 500 people died in ten days. He was determined to find out why.
斯洛推测第二种说法是正确的，但他需要证据。因此，在1854年伦敦再次暴发霍乱的时候，约翰·斯洛着手准备对此进行调研。当霍乱在贫民区迅速蔓延的时候，约翰·斯洛就开始收集资料。他发现特别在两条街道上霍乱流行的很严重，在10天之内就死去了500多人。他决心要查明其原因。
First he marked on a map the exact places where all the dead people had lived. This gave him a valuable clue about the cause of the disease. Many of the deaths were near the water pump in Broad Street (especially numbers 16, 37, 38 and 40). He also noticed that some houses (such as 20
