Description:
This 2006 review of a book about cholera epidemics in the 19th century discusses how English doctor John Snow discovered that this disease was often communicated through people drinking contaminated water (rather than through coming in contact with "noxious miasmas," as many postulated). Topics addressed include the prevalence of cholera among the poor, development of water supply companies, and the use of mapping in epidemiology. From The New Yorker. |
