It was also noted that there was an extremely low incidence of cholera at a nearby work house and also at the Lion Brewery, and both of these businesses had their own water supply. Ultimately, Snow was able to track down 197 victims, the vast majority of whom lived within walking distance of the pump. The board was not convinced, but agreed to remove the pump handle as a precaution. He argued that the pump handle should be removed in order to prevent further contamination.

6 Snow appeared at the meeting of the local Board of Guardians and presented his evidence that the pump was the source of the outbreak. He went to their homes and learned from relatives that the vast majority of them had obtained their water from the Broad St. He obtained the names and the addresses of the first 83 victims who had died by the end of the first week. Water samples did not reveal gross contamination, but Snow persisted and began to collect detailed information on where the victims had gotten their drinking water. A hand pump was located right on Broad Street, and Snow was immediately suspicious. In late August of 1853, cholera broke out in the Broad Street area, and the residents panicked and many began to flee. Nevertheless, many were unconvinced by his findings, since Snow had not actually demonstrated that the water contained something that could cause cholera. Southwark & Vauxhall pumped water from a more downstream location that was clearly contaminated, and the rates of cholera were clearly higher in their customers compared to those supplied by the Lambeth Company. The map of London below shows the areas of London supplied by these two water companies. Some consumers were supplied by the Lambeth Company, while others were supplied by Southwark & Vauxhall. Snow learned from municipal records that two private companies supplied piped in water to the areas that were primarily affected by cholera. However, increasing numbers of businesses and homes had water piped from the Thames River by private companies. Many Londoners received their water from hand pump wells (below) that were located throughout the city. The epidemic ended in 1849, but Snow continued to collect data on the pattern of of disease and began finding evidence that linked cholera to specific sources of water. In August 1849 Snow published a paper entitled ' On the Mode of Communication of Cholera' in which he presented his theory that the disease was acquired by ingestion of contaminated water, but his theory did not get much traction with the medical establishment.

In fact, cholera is caused by the bacterium, Vibrio cholera, which is transmitted by the fecal-oral route, that is by ingestion of water or food that is contaminated with sewage. Snow reasoned that, if cholera was spread by bad air, it should cause pulmonary symptoms, but since the symptoms were gastrointestinal, perhaps it was transmitted by water or food consumption. The prevailing opinion was that cholera was spread either by miasmas or by person-to-person contact, Snow began examining the victims and found that their initial symptoms were always related to the gastrointestinal tract. Another large epidemic occurred in 1848 and lasted through 1849. The first cholera epidemic in London struck in 1831, when Snow was still an apprentice. He is most often credited with solving an outbreak of cholera that occurred in London in 1854 (the outbreak is described below), but his studies of cholera were much more extensive than that. John Snow (shown below) was a physician in London who spent several decades studying cholera in a systematic way. In the 1800s there were large epidemics of cholera in Europe and America that killed thousands of people. Health officials discuss an outbreak of cholera spreading through rural Haiti. The next video describes the cholera epidemic in Haiti in 2010. You Tube video of Steven Johson discussing The Ghost Map.Д¬holera continues to be a problem throughout the world today (see Cholera in Haiti). The story has been elegantly told in The Ghost Map by Steven Johnson, who describes the conditions in London in the 1800s situation in the brief video below. Cholera is an infectious disease that became a major threat to health during the 1800s.
