John Snow

The Life-Saving Heroics Of Cholera Detective John Snow

In the early 19th century, Britain faced a cholera epidemic that took thousands of lives. The first few cholera cases were diagnosed in 1831, and by the following year, the disease had spread in London. Back then, medical professionals theorized that cholera was an airborne illness that spread from rotten organic materials. Authorities and doctors weren't prepared to face the epidemic, and there were disagreements among them on which measures to take to stop cholera from spreading, according to the National Library of Medicine.
