Instead of believing that cholera could be communicated in more than one way—by inhalation from the atmosphere or by drinking contaminated water—Snow argued that it could be communicated solely by what we now call the fecal–oral route. Snow 1 Whereas all epidemiologists are familiar with the account of the Broad Street pump, 2 fewer are familiar with the much larger and more compelling Grand Experiment that Snow exploited in South London.
