#19 Copenhagen Cholera Outbreak – Denmark, 1853
Poor sanitary arrangements and overpopulation were the catalysts for the 1853 cholera outbreak in Copenhagen. It started in June and lasted for several months. Over 7000 people were infected and close to 5000, a mortality rate of 57%.
The outbreak was the tipping point that led to the decommissioning of the fortifications in Copenhagen. Additionally, it led to the construction of a new cattle market in the city, colloquially called the Brown Meat District, besides leading to the installation of safer municipal water supply systems.
The outbreak further motivated the construction of housing facilities in the outskirts of the city for lower-income groups. The construction was sponsored by philanthropists and affluent businessmen.
