Chart Shewing the Progress of the Spasmodic Cholera
Summary
This map uses lines to show cholera’s spread around the world in 1832. These lines closely follow trade routes of the time and therefore contradicted prevailing miasmatic ideas about how cholera spread.
A miasma is polluted air. It was thought that air filled with particles from decomposed matter carried a poison that could cause disease. The miasmatic theory of the transmission of cholera persisted until well after Robert Koch’s publication in 1884 of his discovery that cholera is caused by bacteria.
The USA is drawn to a different scale.
