Consult a health care professional or visit a travel health clinic preferably 6 weeks before you travel to get personalized health advice and recommendations.
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.
Yellow Fever - Country Entry Requirements
Yellow fever is a disease caused by a flavivirus from the bite of an infected mosquito.
Travellers get vaccinated either because it is required to enter a country or because it is recommended for their protection.
- There is no risk of yellow fever in this country.
Country Entry Requirement*
- Proof of vaccination is not required to enter this country.
- Vaccination is not recommended.
* It is important to note that country entry requirements may not reflect your risk of yellow fever at your destination. It is recommended that you contact the nearest diplomatic or consular office of the destination(s) you will be visiting to verify any additional entry requirements.
Hepatitis A is a disease of the liver spread through contaminated food and water or contact with an infected person. All those travelling to regions with a risk of hepatitis A infection should get vaccinated.
Measles is a highly contagious viral disease. It can spread quickly from person to person by direct contact and through droplets in the air.
Anyone who is not protected against measles is at risk of being infected with it when travelling internationally.
Regardless of where you are going, talk to a health care professional before travelling to make sure you are fully protected against measles.
Hepatitis B is a disease of the liver spread through blood or other bodily fluids. Travellers who may be exposed (e.g., through sexual contact, medical treatment, sharing needles, tattooing, acupuncture or occupational exposure) should get vaccinated.
Coronavirus disease (COVID-19) is an infectious viral disease. It can spread from person to person by direct contact and through droplets in the air.
It is recommended that all eligible travellers complete a COVID-19 vaccine series along with any additional recommended doses in Canada before travelling. Evidence shows that vaccines are very effective at preventing severe illness, hospitalization and death from COVID-19. While vaccination provides better protection against serious illness, you may still be at risk of infection from the virus that causes COVID-19. Anyone who has not completed a vaccine series is at increased risk of being infected with the virus that causes COVID-19 and is at greater risk for severe disease when travelling internationally.
Before travelling, verify your destination’s COVID-19 vaccination entry/exit requirements. Regardless of where you are going, talk to a health care professional before travelling to make sure you are adequately protected against COVID-19.
Seasonal influenza occurs worldwide. The flu season usually runs from November to April in the northern hemisphere, between April and October in the southern hemisphere and year round in the tropics. Influenza (flu) is caused by a virus spread from person to person when they cough or sneeze or by touching objects and surfaces that have been contaminated with the virus. Get the flu shot.
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.
There is a risk of chikungunya in this country. The risk may vary between regions of a country. Chikungunya is a virus spread through the bite of an infected mosquito. Chikungunya can cause a viral disease that typically causes fever and pain in the joints. In some cases, the joint pain can be severe and last for months or years.

Some infections, such as rabies and influenza, can be shared between humans and animals. Certain types of activities may put you at higher risk 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’re more likely to come in contact with animals.
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) and HIV are spread through blood and bodily fluids; use condoms, practise safe sex, and limit your number of sexual partners.
Tuberculosis is an infection caused by bacteria and usually affects the lungs.
For most travellers the risk of tuberculosis is low.
Travellers who may be at high risk while travelling in regions with risk of tuberculosis should discuss pre- and post-travel options with a health care professional.
High-risk travellers include those visiting or working in prisons, refugee camps, homeless shelters, or hospitals, or travellers visiting friends and relatives.
Medical services and facilities

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

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.

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.
