About This Book

The author reviews the spread of cholera and compiles clinical and epidemiological evidence to explain its transmission. He presents case studies documenting person-to-person spread and argues against airborne effluvia, using pathological and fluid analyses to show the morbid agent enters the alimentary canal. Multiple outbreak investigations link localized epidemics to polluted water sources, supported by maps, tables, and comparative mortality data across different water supplies, institutions, and neighborhoods. The work assesses environmental and infrastructural factors such as water-company networks, river contamination, elevation, and dry weather that alter exposure risk.

About the Author

John Snow

John Snow was a pioneering English physician and a key figure in the development of modern epidemiology. He is best known for his groundbreaking work on cholera, particularly his influential writings such as "On the Mode of Communication of Cholera," where he argued for the waterborne transmission of the disease. His meticulous investigation during the 1854 cholera outbreak in London, detailed in "Cholera and the Water Supply in the South Districts of London in 1854," laid the foundation for public health reforms. Additionally, Snow made significant contributions to the field of anesthesiology, as seen in his work "On Chloroform and Other Anæsthetics: Their Action and Administration." His legacy continues to impact public health and medical practices today.
