IntroductionBorn on 15 March 1813, John Snow was born and raised in a very poor town near the River Ouse. Because his home was so close to the river, his 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 was able to trace the source of a cholera epidemic to a London water system. The John Snow HypothesisA famous study that Snow conducted was when the cholera epidemic in London's Golden Square took place. By analyzing the relationship between water supply sites and cholera epidemics, Snow derived his hypothesis that contaminated water supplies cause disease epidemics. He managed to arrive at this hypothesis without the help of advanced technologies such as the microscope, which is why his discoveries were of great importance for his time. Keep in mind that bacteria were not known to be possible sources of disease at that time. Even without this knowledge Snow understood the source of the cholera wave and put an end to it. Cholera Epidemic in London In 1854, London was hit hard by an acute infectious disease called cholera. This disease has taken thousands of lives and devastated many families. When an individual becomes infected with cholera, he experiences violent vomiting and diarrhea. Due to the symptoms of cholera, they lose enormous amounts of body fluids and become dangerously dehydrated. If left untreated, the infected person will eventually die. Cholera is a waterborne disease, however when it hit London in 1854 people already believed it was airborne. This is why when John Snow proposed that it was actually an aquatic product, many people thought it was… middle of the paper… and the level of education they received. Similar to how Snow showed the relationship between water supplies 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 these areas. The Role Maps Played in the Cholera Epidemic The map Snow used played a huge role in identifying the source of the cholera surge. By drawing the dots of all the locations of the infected residents and also the water pumps, he could see that a certain pump had the most dots near or around it. The map served as a visual representation of what was happening and was an easy way to prove to himself and officials that the disease was transmitted by water rather than air.
