These epidemics sparked the sanitation reforms in large European cities during the 19th century, after [[John Snow]] traced a cholera outbreak in London to a single pump.<ref>[http://www.csiss.org/classics/content/8 John Snow: The London Cholera Epidemic of 1854] By Scott Crosier</ref>

*In 1883 a German physician, Robert Koch, took the search for the cause of cholera a step further when he isolated the bacterium Vibrio cholerae, the “poison” Snow contended caused cholera. Dr. Koch determined that cholera is not contagious from person to person, but is spread only through unsanitary water or food supply sources, a major victory for Snow’s theory. The cholera epidemics in Europe and the United States in the 19th century ended after cities finally improved water supply sanitation. [http://www.ph.ucla.edu/epi/snow/snowcricketarticle.html]
