John Snow Epidemiologic Triangle

Within as little as a month, an entire population can be obliterated by deadly disease. This might have been the case in a district in London if not for the genius of a local anaesthesiologist who ended one of the most well-known outbreaks of cholera in history by using strategies epidemiologists use to this day.
The year is 1854 in Soho, London where living conditions are abominable. Dense population, lack of waste management, and the dearth of knowledge concerning sickness all contribute to the likelihood of an epidemic. Unfortunately, an outbreak of a fatal disease begins, and rapidly kills the citizens of Soho. John Snow, an anaesthesiologist, takes matters into his own hands to discover what caused this sudden outbreak and how it can be halted. Now named “The Father of Epidemiology”, John Snow utilized methods that epidemiologists use to solve modern problems.
The vertices of the triangle represent the host, the agent, and the environment. If you separate one corner of the triangle from another, the outbreak’s intensity will decrease or the outbreak will stop altogether. A similar model is the chain of infection. Like the epidemiologic triangle, if you disconnect one part from another, the epidemic will end. One major difference between the two is that the chain of infection is more comprehensive, it adds elements that aren’t seen in the epidemiologic triangle such as: a causative agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host. Although both of these models are incredibly crucial, John Snow was detailed in his investigation, therefore, he most likely focused more on the chain of
