Cholera is a bacterial infection that leads to watery diarrhea, and can degenerate into life-threatening dehydration. It's caused by the ingestion of food or water contaminated with the
bacteria Vibrio cholerae.
Who gets it?
The vaccine has been administered to people in East Asia as well as South America, but is not recommended for routine use in the United States. Only people traveling to high-risk cholera areas
should receive it.
What are the side effects?
Common side effects from the vaccine include stomach pain and headaches.
The vaccine is not currently available for routine use in the United States.

If you're traveling to an area where cholera is prevalent, there are ways other than just vaccination to prevent infection: Drink only boiled or bottled water, eat only foods you can peel,
avoid uncooked foods and fish, and do not eat food from street vendors.
