Cholera was spread by germ
Polluted water carried choleraParagraph 6: Prevention of Cholera
John Snow defeats King CholeraNobody knew the cause of the serious disease of choleraa strange cloud of gas found its victimspeople absorbed the disease with mealsCollect information from the cholera outbreak to prove which theory was correctHe found the cause of cholera was the polluted waterIdea 2. Because the information showed that the dirty water carried choleraHe defeated cholera by examining the water supply and dealing with the polluted water Discussion: Discuss the following questions in groups of four.1.2.3.Cholera was a 19th century disease. What disease do you think is similar to cholera today?John Snow believed Idea 2 was right. How did he finally prove it?Do you think John Snow would have solved this problem with- out the map? Give a reason. Two diseases, which are similar today, are SARS and AIDS because they are both very serious, have an unknown cause and public health care to solve them. John Snow finally proved his idea because he found an outbreak that was clearly related to cholera, collected information and was able to tie cases outside the area to the polluted water.Keys1.2. No. The map helped John Snow organise his ideas. He was able to identify those households that had had many deaths and check their water-drinking habits. He identified those houses that had had no deaths and surveyed their drinking habits. The evidence clearly pointed to the polluted water being the cause.3.Read the passage again and fill in the blanks:
