How common is cholera?

Millions of people across the world get cholera infections each year. The bacterial infection usually happens in places without modern systems for sewage and clean water. Examples include undeveloped countries and refugee camps, as well as parts of the Middle East, Asia, South America and Africa.

Cholera outbreaks are more common in warm climates. Outbreaks sometimes happen after natural disasters, like earthquakes and hurricanes. These disasters can damage sewage systems.

Cholera is rare in the United States and other modern, industrialized countries. But Americans should be aware of the disease and its causes, especially if they travel internationally.
