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.
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.
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.
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 16,37,38and40).He also noticed that some houses(such as 20 and 21 Broad Street and 8and 9 Cambridge Street)had had no deaths.He had not foreseen this,so he made further investigations.He discovered that these people worked in the pub at 7 Cambridge Street.They had been given free beer and so had not drunk the water from the pump.It seemed that the water was to blame.
Next,John Snow looked into the source of the water for these two streets.He found that it came from the river polluted by the dirty water from London.He immediately told the astonished people in Broad Street to remove the handle from the pump so that it could not be used.Soon afterwards the disease slowed down.He had shown that cholera was spread by germs and not in a cloud of gas.
In another part of London,he found supporting evidence from two other deaths that were linked to the Broad Street outbreak.A woman,who had moved away from Broad Street,liked the water from the pump so much that she had it delivered to her house every day.Both she and her daughter died of cholera after drinking the water.With this extra evidence John Snow was able to announce with certainty that polluted water carried the virus.
To prevent this from happening again,John Snow suggested that the source of all the water supplies be examined.The water companies were instructed not to expose people to polluted water any more.Finally "King Cholera"was defeated.

约翰·斯诺是一位著名的医生在London-so专家,他参加了维多利亚女王作为她的私人医生但是他时,他一想到要帮助灵感的普通老百姓,霍乱这是致命的疾病的日子.既不知道它的原因也不了解它的治疗方法很多人死于成千上万感到每时每刻都有一种爆发约翰·斯诺要面对的挑战,解决这个问题他知道,霍乱也不可控制的原因被发现之前.
他变得有兴趣,可能解释两种学说
如何杀人.霍乱第一个建议霍乱增多在空气中…云的有害气体,直到它发现飘忽不定的受害者第二个建议人们把这种病毒进入他们的尸体在吃饭的时候从胃肠疾病快速攻击身体很快患者的死亡.
约翰·斯诺怀疑第二的理论是正确的,但他需要证据所以当另一暴发打伦敦1854年他已经准备好开始询问由于本病很快蔓延到贫困地区,他开始收集信息在两个特殊的街道,霍乱爆发是如此严重,500多人死于10天.他下定决心要找到原因.
他先在地图上所有的确切地点的死人.这给了他一个有价值的线索关于这种病的起因的.许多的死亡人数接近水泵在宽阔的街道(特别是编号16,37岁,38and40).他也注意到一些房屋(如20、21宽阔的街道和主街道)9剑桥没有死亡他没有预见到这,所以他做了进一步的调查他发现,这些人曾在酒吧街7剑桥…他们所提供的免费啤酒,所以没有喝的水从泵似乎这水是罪魁祸首.
约翰·斯诺注视下,水的来源,这两个街道他发现,它来自于河流污染肮脏的水是从伦敦来的.他立刻告诉那些人在宽阔的街道的把手,泵,所以它并不能用此后不久,疾病慢下来他已表明霍乱是由细菌传播,而不是在一团气体.
在另一边的伦敦,他发现的证据来自另外两个死亡,被连接到百老汇大街爆发一个女人,离开了百老汇大街,喜欢水从泵,以至于她就交给她的房子的每一天.她和她的女儿死于霍乱喝完水这个额外的证据可以宣布约翰雪断定被污染的水将该病毒.
为防止这种情况再次发生,斯诺指出所有的水供应来源审查水公司被告知不要让人们暴露在污染的水有更多“莫莫王”最终战败.霍乱
