Health

Routine vaccines

Be sure that your routine vaccinations, as per your province or territory, are up-to-date before travelling, regardless of your destination.

Some of these vaccinations include measles-mumps-rubella (MMR), diphtheria, tetanus, pertussis, polio, varicella (chickenpox), influenza and others.

Pre-travel vaccines and medications

You may be at risk for preventable diseases while travelling in this destination. Talk to a travel health professional about which medications or vaccines may be right for you, based on your destination and itinerary. 

Safe food and water precautions

Many illnesses can be caused by eating food or drinking beverages contaminated by bacteria, parasites, toxins, or viruses, or by swimming or bathing in contaminated water.

• Learn more about food and water precautions to take to avoid getting sick by visiting our eat and drink safely abroad page. Remember: Boil it, cook it, peel it, or leave it!
• Avoid getting water into your eyes, mouth or nose when swimming or participating in activities in freshwater (streams, canals, lakes), particularly after flooding or heavy rain. Water may look clean but could still be polluted or contaminated.
• Avoid inhaling or swallowing water while bathing, showering, or swimming in pools or hot tubs. 

Insect bite prevention

Many diseases are spread by the bites of infected insects such as mosquitoes, ticks, fleas or flies. When travelling to areas where infected insects may be present:

• Use insect repellent (bug spray) on exposed skin
• Cover up with light-coloured, loose clothes made of tightly woven materials such as nylon or polyester
• Minimize exposure to insects
• Use mosquito netting when sleeping outdoors or in buildings that are not fully enclosed

To learn more about how you can reduce your risk of infection and disease caused by bites, both at home and abroad, visit our insect bite prevention page.

Find out what types of insects are present where you’re travelling, when they’re most active, and the symptoms of the diseases they spread.

Animal precautions

Some infections, such as rabies and influenza, can be shared between humans and animals. Certain types of activities may increase your chance of contact with animals, such as travelling in rural or forested areas, camping, hiking, and visiting wet markets (places where live animals are slaughtered and sold) or caves.

Travellers are cautioned to avoid contact with animals, including dogs, livestock (pigs, cows), monkeys, snakes, rodents, birds, and bats, and to avoid eating undercooked wild game.

Closely supervise children, as they are more likely to come in contact with animals.

Person-to-person infections

Stay home if you’re sick and practise proper cough and sneeze etiquette, which includes coughing or sneezing into a tissue or the bend of your arm, not your hand. Reduce your risk of colds, the flu and other illnesses by:

•  washing your hands often
• avoiding or limiting the amount of time spent in closed spaces, crowded places, or at large-scale events (concerts, sporting events, rallies)
• avoiding close physical contact with people who may be showing symptoms of illness 

Sexually transmitted infections (STIs), HIV, and mpox are spread through blood and bodily fluids; use condoms, practise safe sex, and limit your number of sexual partners. Check with your local public health authority pre-travel to determine your eligibility for mpox vaccine.  

Medical services and facilities

Medical services and facilities are very good and are widely available.

Make sure you get travel insurance that includes coverage for medical evacuation and hospital stays.

Health and safety outside Canada

Keep in Mind...

The decision to travel is the sole responsibility of the traveller. The traveller is also responsible for his or her own personal safety.

Be prepared. Do not expect medical services to be the same as in Canada. Pack a travel health kit, especially if you will be travelling away from major city centres.

Laws and culture

You must abide by local laws.

Learn about what you should do and how we can help if you are arrested or detained abroad.

Drugs

Penalties for possession, use or trafficking of illegal drugs are severe. Convicted offenders can expect lengthy jail sentences and heavy fines.

International Child Abduction

The Hague Convention on the Civil Aspects of International Child Abduction is an international treaty. It can help parents with the return of children who have been removed to or retained in certain countries in violation of custody rights. The convention applies between Canada and Guam.

If your child was wrongfully taken to, or is being held in Guam, and if the applicable conditions are met, you may apply for the return of your child to the Guamanian court.

If you are in this situation:

• act as quickly as you can
• contact the Central Authority for your province or territory of residence for information on starting an application under The Hague Convention
• consult a lawyer in Canada and in Guam to explore all the legal options for the return of your child
• report the situation to the nearest Canadian government office abroad or to the Vulnerable Children's Consular Unit at Global Affairs Canada by calling the Emergency Watch and Response Centre

If your child was removed from a country other than Canada, consult a lawyer to determine if The Hague Convention applies.

Be aware that Canadian consular officials cannot interfere in private legal matters or in another country's judicial affairs.
