Map: Diphtheria Contagion from Detroit 1892

Detroit is no stranger to excessive contagion.

The cholera epidemics of 1832 and 1834 led the city to develop a sewerage (yes that is the correct term) system that most comprised of cementing over historic rivers and creeks (i.e. Connors Creek). Cholera was found to spread when human waste was dumped into the river and collected along the wharfs that no longer jut out from the riverfront.

The 1918 spanish flu pandemic led to mass support for investment in the public health system with additional funding for the Herman Kiefer Health Complex, which opened in 1919. The complex was shuttered in 2013 and has since been sold to a developer in 2015.

The map above is from the [Michigan] State Board of Health – Report of Secretary, 1893 showing:

[…] instances where diphtheria was reported to have been carried from one locality to another; the lines connect the localities, and the arrow-heads indicate the direction of movement in each case. […]

It will be noted that in 1892 Detroit was the greatest source of contagium. The evidence in this map bears upon statements made later in this article, that “The evidence of the spread of diphtheria from cities is conclusive, etc.”

One thought on “Map: Diphtheria Contagion from Detroit 1892

  1. This is an interesting map. I wonder if there are any maps of cholera deaths in Detroit in
    1832 and 1834. I am told that a group of German immigrants removed themselves to
    a location quite far out on Gratiot and experienced lower mortality rates than the Irish
    immigrants. There is a book about Cholera in Detroit in the 1830s. I believe that
    epidemic took the life of one of the two founders of the University of Michigan: Father Gabriel Richard.
