1854 Broad Street Cholera Outbreak

Introduction

The 1854 Broad Street cholera outbreak was a significant event in the history of public health and epidemiology. Occurring in Soho, London, this outbreak was a pivotal incident in understanding the transmission of cholera and the development of modern epidemiological methods.

Background

Cholera, a severe waterborne disease caused by the bacterium Vibrio cholerae, was a major health threat in the 19th century. The 1854 outbreak in London was part of a larger cholera pandemic that affected the entire world.

The Outbreak

In August 1854, a major outbreak of cholera occurred in Soho. Within a short period, hundreds of people contracted the disease, leading to a high mortality rate. The outbreak was centered around Broad Street (now Broadwick Street).

Dr. John Snow's Investigation

Dr. John Snow, a British physician, conducted groundbreaking work during this outbreak. He:

• Mapped the cases of cholera in the Soho district.
• Identified the Broad Street water pump as the outbreak's epicenter.
• Used statistical methods to support his hypothesis that cholera was waterborne.
