Printed Cholera Notice, paper, 1866. LSHTM Library & Archives
After Snow's death in 1858, a final cholera outbreak hit areas of East London not yet connected to the new sewer system. The inhabitants there were forced to use drinking water contaminated with faeces of other Londoners which bought about the start of a new epidemic. This new evidence bolstered Snow's theory that the cholera agent was being transmitted through contaminated water and professional and public opinion was soon won over as indicated in this printed notice.
