Elimination of Cholera in Europe and North America
The first link between cholera disease and contaminated drinking water was found in England in 1854, by Dr. John Snow, a famous physician and medical scientist. He proposed a precise model for the study of the cause of the disease (State of the art review, J. Snow, 1855).
Once convinced of the plausibility of the model, developed countries in Europe and North America made massive investments in infrastructures for potable water treatment and supply and sewage treatment. These investments in Water, Sanitation and Hygiene, eliminated the threat of cholera in the major developed cities in Europe and North America.
