Hundreds of thousands of people died as a result of this pandemic, including many British soldiers, which attracted European attention. This was the first of several cholera pandemics to ...
An exhaustive study into environmental factors influencing the spread of cholera in Haiti cites above average air temperatures following the earthquake, "anomalously high rainfall" from September to October 2010, and damage to the limited water and sanitation infrastructure as likely converging to create conditions favorable to a cholera outbreak.
