Cholera John Snow Map. Figure 2 from Crediting his critics' concerns remaking John Snow's map of Broad Street cholera The purpose of this research is to recreate John Snow Cholera outbreak analysis in Broad street-London 1854 The Broad Street cholera outbreak (or Golden Square outbreak) was a severe outbreak of cholera that occurred in 1854 near Broad Street (now Broadwick Street) in Soho, London, England, during the worldwide 1846-1860 cholera pandemic.The Broad Street outbreak, which killed 616 people, is best known for the physician John Snow's study of its causes and his hypothesis that germ-contaminated.

John Snow's map was able to spatially associate cholera cases with a single contaminated water pump Looking at John Snow's Cholera map from the twenty first century: A practical primer on reproducibility and open science
Snow's map of the Cholera outbreak of 1854, and the reports that it accompanied, eventually won over the medical community of the day, as well as the burgeoning public health system in London, and by the time London saw another outbreak of Cholera, most had been convinced. A more recent example of cholera spread was in April of 2000 when an outbreak in Micronesia infected thousands of people. This was done using two main data layers, cholera deaths and pump data
John Snow and the 1854 Cholera Outbreak Past Medical History. Snow's map of the Cholera outbreak of 1854, and the reports that it accompanied, eventually won over the medical community of the day, as well as the burgeoning public health system in London, and by the time London saw another outbreak of Cholera, most had been convinced. By seeing, visually, where the cholera deaths were clustered, Snow showed that the water from a pump on Broad Street was to blame
. John Snow's map was able to spatially associate cholera cases with a single contaminated water pump This led to three positive changes: the water pump was disabled, preventing further deaths, cholera was identified as a waterborne disease, and efforts began to improve water and waste systems in London.
