IntroductionBorn on March 15, 1813, John Snow was born and raised in a very poor town near the River Ouse. Because her house was so close to the river, her neighborhood was always at risk of flooding. Snow studied and became an anesthesiologist. Later in his life, Snow earned the title "father of epidemiology" when he successfully traced the source of a cholera outbreak to a London water supply. John Snow's Hypothesis A famous study that Snow carried out concerned the cholera epidemic. at the Golden Square in London. Analyzing the relationship between water supply sites and cholera outbreaks, Snow formulated his hypothesis that contaminated water supplies cause outbreaks. He was able to arrive at this hypothesis without the aid of advanced technology such as the microscope, which is why his discoveries were of great importance for his time. Keep in mind that at that time it was not known that bacteria could cause illness. Even without this knowledge, Snow discovered the source of the cholera wave and put an end to it. Cholera outbreak in London In 1854, London was hit hard by an acute infectious disease called cholera. This disease has claimed thousands of lives and devastated many families. When a person is infected with cholera, they suffer from severe vomiting and diarrhea. Due to cholera symptoms, they lose huge amounts of body fluids and become dangerously dehydrated. If left untreated, the infected person will eventually die. Cholera is a waterborne disease, but when it hit London in 1854, people already thought it was airborne. That's why when John Snow proposed that it was actually a water-based substance, many people thought he... middle of paper ... and the level of education they received. In the same way that Snow showed the relationship between water supply and cholera deaths, this type of data would compare social determinants of health and cholera deaths. The areas where cholera broke out were poverty-stricken, so health disparities certainly played a role in those areas. The Role Maps Played in the Cholera Outbreak The spot map Snow used played a huge role in identifying the source of the cholera wave. By drawing points of all the locations of infected residents as well as water pumps, he was able to see that a certain pump had the most points near or around it. The map served as a visual representation of what was happening and was a simple way to show himself and the authorities that the disease was waterborne rather than airborne.
