Prevention
Cholera is rare in the United States with the few cases related to travel outside the U.S. or to contaminated and improperly cooked seafood from the Gulf Coast waters.
If you’re traveling to areas known to have cholera, your risk of contracting the disease is extremely low if you follow these precautions:
Wash your hands with soap and water frequently, especially after using the toilet and before handling food. Rub soapy, wet hands together for at least 15 seconds before rinsing. If soap and water aren’t available, use an alcohol-based hand sanitizer.
Drink only safe water, including bottled water or water you’ve boiled or disinfected yourself. Use bottled water even to brush your teeth.
Hot beverages are generally safe, as are canned or bottled drinks, but wipe the outside before you open them. Don’t add ice to your drinks unless you made it yourself using safe water.
Eat food that’s completely cooked and hot and avoid street vendor food, if possible. If you do buy a meal from a street vendor, make sure it’s cooked in your presence and served hot.
Avoid sushi, as well as raw or improperly cooked fish and seafood of any kind.
Stick to fruits and vegetables that you can peel yourself, such as bananas, oranges and avocados. Stay away from salads and fruits that can’t be peeled, such as grapes and berries.
Cholera vaccine
People traveling from the United States to areas affected by cholera can get a cholera vaccine called Vaxchora. It’s suggested for people between ages 2 and 64 who plan to travel where cholera is being spread or regularly spreads. It is a liquid dose taken by mouth at least 10 days before travel.
Several other countries offer oral vaccines as well. Contact your doctor or local office of public health for more information about these vaccines. Even with the vaccine, it’s important to take the above precautions to prevent cholera.
