Broad Street outbreak

The Broad Street outbreak refers to a significant cholera epidemic in 1854 in Soho, London. Dr. John Snow traced the source to a contaminated water pump on Broad Street, where many affected residents drank water from that source. His investigation helped identify water supply as a key factor in the spread of cholera, leading to improvements in sanitation and public health practices. This event is considered a pivotal moment in epidemiology, demonstrating how disease transmission can be linked to contaminated resources and highlighting the importance of clean water for health.
