Hepatitis A Vaccine for Travel: What Canadian Travellers Should Know

Planning an international trip involves more than booking flights and accommodations. Taking a few steps to prepare for your health before departure can help you travel with greater confidence. One of the most common vaccine-preventable illnesses associated with international travel is Hepatitis A.

What Is Hepatitis A?

Hepatitis A is a viral infection that affects the liver. The virus is most commonly spread through the consumption of contaminated food or water or through close contact with an infected person. In many parts of the world, the risk of exposure may be higher than it is in Canada.

Because the virus can be transmitted through everyday activities such as eating or drinking, travel health professionals often consider Hepatitis A when assessing travel-related health risks.

How Is Hepatitis A Transmitted?

Hepatitis A is generally spread through the fecal-oral route. Potential sources of exposure may include:

• Contaminated food or beverages

• Drinking water that may not meet local safety standards

• Ice made from contaminated water

• Raw or undercooked foods

• Close personal contact with an infected individual

Even travellers staying in quality accommodations and dining at reputable restaurants may not always be able to completely eliminate the risk of exposure.

Why Is Hepatitis A Relevant for International Travellers?

The likelihood of exposure to Hepatitis A can vary depending on the destination, local sanitation conditions, length of stay, and planned activities. For this reason, travel health recommendations are often individualized rather than the same for every traveller.

Canadian travel health resources encourage travellers to review their health needs before departure, particularly when travelling to regions where Hepatitis A is more common.

What Are the Symptoms?

Symptoms of Hepatitis A may develop several weeks after exposure and can vary from person to person. They may include:

• Fatigue

• Fever

• Nausea or vomiting

• Loss of appetite

• Abdominal discomfort

• Dark urine

• Yellowing of the skin or eyes (jaundice)

Some people experience mild illness, while others may require a longer period of recovery.

Can Vaccination Help Protect Travellers?

According to Canadian immunization guidance, Hepatitis A vaccination may be recommended for some travellers depending on their destination and individual circumstances. The decision to receive a travel vaccine should be based on a personal risk assessment that considers factors such as travel itinerary, duration of travel, medical history, and planned activities.

A travel health consultation can help determine whether Hepatitis A vaccination or other preventive measures may be appropriate for your trip.

When Should You Consider a Travel Health Consultation?

Many travel health authorities recommend arranging a travel health consultation several weeks before departure whenever possible. This provides an opportunity to review routine immunizations, discuss destination-specific health considerations, and receive personalized travel health advice.

Even if your departure date is approaching, it may still be beneficial to speak with a qualified travel health professional.

Travel Safely and Stay Informed

International travel offers exciting opportunities to experience new cultures and destinations. Preparing for your health before you leave can help reduce the risk of preventable travel-related illnesses and allow you to focus on enjoying your trip.

If you are planning to travel outside of Canada, consider consulting a travel health clinic to discuss destination-specific recommendations and to ensure you have the information you need before departure.
