While Snow believed that there was a correlation between poverty and cholera, his counter parts, such as the city sanitarians did not consider the connection between poverty and the cholera disease rates.

In the mid-1800s, an anesthesiologist named John Snow was conducting a series of investigations in London that warrant his being considered the “father of field epidemiology.” Twenty years before the development of the microscope, Snow conducted studies of cholera outbreaks both to discover the cause of disease and to prevent its recurrence. people’s individual experiences such as their social class, and their In studying the distribution of cholera, he could only count deaths, because no systematic information was available on all cases. having sex with an individual that has traveled in high risk areas within three However, the evening before, he did convince the municipal authorities to remove the handle of the popular water pump near the corner of Broad and Cambridge Streets in Soho.
