Chart Indicating the March of Cholera in 1865
Note: the chart “actually maps the pandemic’s diffusion from 1865 into the 1870s” (Koch, p. 160).
“From the pandemic’s origin in India, it moves first by sea routes and then over land into Africa, the Middle East, Europe, and finally to Britain, from which it travels to Canada and the United States.” (Koch, p. 160)
This “English Government Map” was included in the U.S. Congressional report by J.M. Woodworth (1875).
The image was scanned from Fig 7.1 in Koch (2005).
