Podcast 566: The Cholera Pandemic

Contributor: Jared Scott, MD

Educational Pearls:

• Cholera has been responsible for 6 previous global pandemics and currently the world is in the seventh pandemic of cholera, ongoing since 1961.
• Cholera originated in the Ganges Delta of India and spread worldwide but largely is unseen in the US and other developed countries due to water sanitation
• Cholera is a bacterial illness that is water borne and causes severe diarrhea
• Estimates say that there are 1.3-4 million cases annually and up to 143,000 people die each year from Cholera.
• Treatment is largely supportive and can be done with oral rehydration therapy consisting of water, salt, and sugar.
• There are three oral vaccinations for Cholera but unfortunately are not widely available
• Cholera has been responsible for ushering in public health initiatives. Most famously when John Snow was able to isolate a single water source causing Cholera infections in London and by shutting it off eradicated the bacteria
