http://en.wikipedia.org/wiki/1854_Broad_Street_cholera_outbreak
The Broad Street cholera outbreak was a severe outbreak of cholera that occurred near Broad Street (now renamed Broadwick Street) in Soho district of London, England in 1854. This outbreak is best known for the physician John Snow's study of the outbreak and his discovery that cholera is spread by contaminated water. This discovery came to influence public health and the construction of improved sanitation facilities beginning in the 19th century. Later, the term "focus of infection" would be used to describe places like the Broad Street pump in which conditions are ripe for transmission of an infection.

John Snow (15 March 1813 – 16 June 1858) was an English physician and a leader in the adoption of anaesthesia and medical hygiene. He is considered one of the fathers of modern epidemiology, in part because of his work in tracing the source of a cholera outbreak in Soho, London, in 1854. His findings inspired fundamental changes in the water and waste systems of London, which led to similar changes in other cities, and a significant improvement in general public health around the world.

4.What is cholera?
http://en.wikipedia.org/wiki/Cholera
Cholera is an infection of the small intestine caused by the bacterium Vibrio cholerae.
The main symptoms are watery diarrhea and vomiting. This may result in dehydration and in severe cases grayish-bluish skin.^[1] Transmission occurs primarily by drinking water or eating food that has been contaminated by the feces (waste product) of an infected person, including one with no apparent symptoms.
The severity of the diarrhea and vomiting can lead to rapid dehydration and electrolyte imbalance, and death in some cases. The primary treatment is oral rehydration therapy, typically with oral rehydration solution, to replace water and electrolytes. If this is not tolerated or does not provide improvement fast enough, intravenous fluids can also be used. Antibacterial drugs are beneficial in those with severe disease to shorten its duration and severity.
Worldwide, it affects 3–5 million people and causes 100,000–130,000 deaths a year as of 2010^[update]. Cholera was one of the earliest infections to be studied by epidemiological methods.
