Who was the first person to map the cholera epidemic?
Mapping the Cholera Epidemic of 1854. Dr. John Snow is regarded as one of the founding fathers of modern epidemiology. During a major cholera epidemic in 1854 London, he collected and mapped data on the locations (street addresses) where cholera deaths occurred. His process was laborious and slow, but ultimately very informative.
What does the yellow area on the Soho map mean?
Click OK, then Done. Your map now looks like this. The yellow area indicates the part of Soho where the greatest number of cholera deaths occurred. As you move through orange, red, and purple to blue areas, the density of cholera cases drops off.
How did Snow analyze cholera?
Geocoding the addresses and cholera data opens the door to many analysis processes in GIS. We’ll employ only one of these analysis processes today. We’ll analyze the location of cholera cases by creating a heat map. Heat maps use point layer data to calculate and display relative density. The colors are most intense where the most points are concentrated together. Here, we don’t want to locate where the greatest number of dots is but rather the greatest number of cases.
What was the name of the water pump in Soho?
Click on the pump symbol in the center of the yellow area to learn its name. This is the famous Broad Street pump.

When the pump handle was removed, preventing people from using it, the epidemic came to an end. Through spatial analysis, many lives were saved and cholera was confirmed as a water-borne disease.

When was the Broad Street cholera outbreak?
To prove his theory, he began work on a “grand experiment” in 1853.

What did Sbnow think of cholera?
It defied the conventional belief that cholera (a disease that had arrived in Europe from Asia) was an airborne disease, spread by mysterious ‘miasmas’ that polluted the air with a strange killer disease. He hypothesised that the disease was carried in water sources, which had come into contact with cholera via the excrement of infected persons.
What was the most unsanitary place in the world in Victorian times?
Victorian London was an incredibly unsanitary place, and the Thames was the stinky centre of it all. At this time, London’s famous sewer systems were incomplete, and much of the populace dumped their sewage into the river directly or in poorly maintained cesspools.

How much water does cholera cause?
The classic symptoms of cholera are sudden onset profuse, watery diarrhoea, and nausea and vomiting. Its effects are dramatic, and up to 20 litres of water can be lost per day. If not replaced, this heavy fluid loss rapidly leads to severe dehydration, circulatory collapse, and in many cases, death.

What was the cholera epidemic in London?
The cholera epidemic in London was considered the worst of its type in history. Luckily for Londoners and humanity, physician John Snow was on hand to study the pattern of illness, and he determined a “focus of infection” on the Broad Street water pump. Snow had suspected the long held belief in “bad air” and “miasma” was just Medieval nonsense, and that cholera may be a water borne illness.
What was the source of cholera?
His investigation revealed the source of the illness to be the Broad Street water pump which seemed to validate his hypothesis. Further evidence that water from this pump was the source of the infection was the finding that workers in the immediate area of the pump had not become ill, and coincidentally had been given beer rations instead of drinking the local water. Snow also discovered the source of the water pumped to Broad Street as coming from a highly polluted sewage laden area of the Thames River, and notably within 3 feet of a leaking cesspool!
What was Snow's work?
Snow’s work, bolstered by pin maps and support of other researchers convinced the Board of Health to inspect other water sources and ensure none of them were obviously contaminated by raw sewage and cesspools. This action undoubtedly saved many from illness and death until the germ/microbe theory of disease spreading became generally accepted and applied to civil projects. Despite the evidence and the actions of the Board of Health, the official report of the Board was that “miasma” was to blame for the outbreak! It seems old myths die hard, and this report is one more example.
How do you know if you have a bacterial infection?
Different forms of the bacteria cause different levels of illness, and the usual form of infection is caused by drinking contaminated water.

Snow also discovered the source of the water pumped to Broad Street as coming from a highly polluted sewage laden area of the Thames River, and notably within 3 feet of a leaking cesspool!

What Is Cholera?
Cholera is an infectious disease caused by a bacterium called Vibrio cholerae. The bacteria typically live in waters that are somewhat salty and warm, such as estuaries and waters along coastal areas. People contract V. cholerae after drinking liquids or eating foods contaminated with the bacteria, such as raw or undercooked shellfish.

Though the current cholera pandemic has affected some 120 countries, it’s largely a disease of impoverished, less-developed nations.
Why did the public become scared of cholera?
But the public became gripped with widespread fear of the disease and distrust of authority figures, most of all doctors. Unbalanced press reporting led people to think that more victims died in the hospital than their homes, and the public began to believe that victims taken to hospitals were killed by doctors for anatomical dissection, an outcome they referred to as “Burking.” This fear resulted in several “cholera riots” in Liverpool.
Was Cholera Contagious?
For most of the 19th century, most scientists, physicians and sophisticated lay people believed cholera was not contagious. The observation that a doctor could have daily contact with cholera patients without falling ill led to the conclusions that cholera was not transmitted from person to person. This was an accurate observation given that cholera is usually transmitted through contaminated drinking water, as John Snow first demonstrated in 1855.
Why did the cholera epidemic end?
By the end of the 19th century, cholera epidemics no longer appeared in Europe and North America. The reasons for this are uncertain, but standards of living had risen and many communities had made major changes in sanitation practices and established permanent boards of health. As part of the transformation to the germ theory, medical thought had changed in many ways as well. In 1831, most physicians believed cholera to be a nonspecific, noncontagious miasmatic condition that favored the morally and physically predisposed. By the end of the 19th century, although the miasmatic interpretation still had influence, cholera was primarily understood to be a specific contagious disease caused by a particular microscopic organism.
What were the causes of cholera?
Causes of Cholera. For much of the century, most European and American physicians believed cholera was a locally produced miasmatic disease —an illness brought about by direct exposure to the products of filth and decay. Climate and geographic location were also factors.
What factors were most likely to cause cholera?
It was a common assumption that those who engaged in morally and physically intemperate behavior or who had inferior cultural practices were more likely to get cholera when exposed to these miasmas and environmental conditions.
Why was quarantine important?
Quarantine, intimately related to contagion, was another important topic at the Conferences, since it was of central concern to government officials and those involved in commerce. For if cholera was not contagious, there was no reason to submit to the significant personal and economic sacrifices involved in quarantines.
What were the medical treatments that physicians used?
Physicians, when called, would use such characteristic treatments as bleeding or opium. Homeopathic methods were popular among the middle and upper classes, as were other eclectic treatments, and all manner of dietary and hygienic regimens were promoted in newspapers and books.
Is cholera contagious with bacillus?
The existence of the cholera bacillus did not necessarily prove cholera’s contagiousness either; some argued that the bacillus was the product of the disease, not its cause. Another issue was how to explain the existence of healthy carriers—people who had the cholera bacillus in their bodies but who were not sick.
