Which site is linked to an investigation of a cholera outbreak?

The Broad Street Pump is historically linked to a significant investigation of a cholera outbreak in London during the 19th century. This case is particularly notable because it was one of the early examples of epidemiology in action. John Snow, a physician, meticulously mapped the cases of cholera in the Soho area and identified that people who were drinking water from the Broad Street Pump were predominantly affected by the disease.

By advocating for the removal of the pump handle, he effectively cut off the water supply that was spreading the cholera infection. This breakthrough provided crucial evidence supporting the germ theory of disease and highlighted the importance of sanitation in public health. The investigation surrounding the Broad Street Pump established foundational principles of epidemiology and water safety measures that inform modern public health practices today.

The other options, while related to public health, do not encompass the same level of direct linkage to the cholera outbreak investigation that the Broad Street Pump has become emblematic of in public health history. The John Snow Pub is named in honor of John Snow but is not directly related to the outbreak investigation itself. The Thames River and St. Thomas' Hospital are relevant to the context of the era but do not serve as focal points of the cholera investigation like the Broad Street Pump
