About cholera
Cholera is an acute diarrheal infection caused by ingesting food or water contaminated with the bacterium Vibrio cholerae. Cholera causes watery diarrhea and can quickly lead to severe dehydration. In severe cases it can lead to death if left untreated.

Cholera is endemic in many countries around the world. Every year there are between 1.3 to 4 million cases of cholera, with between 20 000 to 140 000 deaths. Travellers to tourist areas that practise safe food and water precautions and good hand hygiene are at low risk.

Cholera outbreaks
The World Health Organization has confirmed outbreaks of cholera in the following countries in Africa and Western Asia:

Eat and drink safely

Always take precautions with food and water to avoid getting sick.
Only eat foods that are well cooked and served hot.
Drink water that has been boiled, disinfected or is in a commercially sealed bottle.
Practise good hand hygiene

Wash your hands frequently with soap and water for at least 20 seconds. Do this as often as possible, including before eating or preparing food and after using the bathroom or changing diapers.
Use alcohol-based hand sanitizer if soap and water are not available. Always keep a bottle of hand sanitizer with you when you travel.
Consider vaccination

Higher risk travellers may benefit from vaccination and should consult with a health care professional to discuss this option. Travellers at higher risk for cholera include:
travellers visiting areas with limited access to clean water, who do not follow proper hand hygiene precautions, or eat raw or poorly cooked food
aid or humanitarian workers
If you develop symptoms

If you experience severe diarrhea and/or vomiting while travelling or after you return to Canada:

Seek medical attention immediately.
Tell a health care professional where you have been travelling or living.
Drink fluids and use oral rehydration solutions to prevent dehydration.
Infants, young children, the elderly and those with underlying health conditions are at greatest risk of dehydration.
If you notice symptoms of cholera during the flight, tell the flight attendant before you land or the border services officer as you enter the country. They will notify a quarantine officer who will assess your symptoms.
