1854 Broad Street cholera outbreak

Severe outbreak of cholera that occurred in 1854 during the 1846–1860 cholera pandemic happening worldwide

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 the Soho district of the City of Westminster, London, England, and occurred during the 1846–1860 cholera pandemic happening worldwide. This outbreak, which killed 616 people, is best known for the physician John Snow's study of its causes and his hypothesis that germ-contaminated water was the source of cholera, rather than particles in the air (referred to as "miasmata"). This discovery came to influence public health and the construction of improved sanitation facilities beginning in the mid-19th century. Later, the term "focus of infection" started to be used to describe sites, such as the Broad Street pump, in which conditions are good for transmission of an infection. Snow's endeavor to find the cause of the transmission of cholera caused him to unknowingly create a double-blind experiment.
