Hepatitis A: The Virus You Don’t Want as a Travel Companion

Hepatitis A is a virus that causes inflammation of the liver⁽¹⁾. Symptoms can be as mild as fatigue, nausea, and stomach pain, or as severe as jaundice (yellowing of the skin and eyes), dark urine, and pale stool. These symptoms typically appear 15 to 59 days after exposure⁽¹⁾.

Interestingly, young children infected with the virus often show no symptoms at all, making it harder to detect and control⁽²⁾. While most people recover within two months, about 10-15% of cases experience prolonged illness lasting 6 to 9 months⁽²⁾. In rare situations, Hepatitis A can lead to liver failure or even become life-threatening^(1,2).

A Surprising Gap in Protection: Are You Vaccinated?

Here’s a fun fact: Here’s a fact that might surprise you: Hepatitis A vaccination became routine to all children in the U.S. only in 2006. If you’re older than that, you might not be protected⁽³⁾. In Canada, it’s even less common, as vaccines are only recommended for high-risk groups⁽⁴⁾. That leaves a significant number of adults vulnerable—especially when traveling.

How Hepatitis A Sneaks Into Your Life: Transmission Made Simple

Hepatitis A isn’t just a virus—it’s a stealthy infiltrator. It spreads through⁽¹⁾:

• Contaminated food or water
• Inadequate sanitation
• Poor personal hygiene
• Direct contact with an infected person (e.g., oral-anal contact)

Picture this: if a food handler doesn’t wash their hands properly, the virus can hitch a ride on your meal. It’s not just about the food—it’s about hygiene.

The Hepatitis A Vaccine: Your Best Defense Against a Sneaky Virus

The Hepatitis A vaccine is your best defense with at least 90 to 97% effectiveness, offering long-term protection^(2,4).

Who Needs It Most: Travelers to high/intermediate-risk areas (Asia, Africa, Central and South America, Eastern Europe), use of recreational drugs, sex between men, and those in close contact with infected individuals.
Don’t wait—consult your doctor, especially if your trip is around the corner. Even one dose can provide short-term protection, best to get the vaccine greater than 2 weeks before arrival⁽²⁾.

• Hepatitis A Vaccine: Havrix, Vaqta, Avaxim
• Combined Hepatitis A and B: Twinrix

How It Works: Two doses, six months apart, ensure immunity for up to 20+ years⁽²⁾.

Beyond the Vaccine: Everyday Prevention Tips

Vaccination is crucial, but additional precautions can keep you safe⁽²⁾:

• Food Safety: Steer clear of raw or undercooked foods in high-risk areas. Heat food to over 185°F for at least a minute to neutralize the virus.
• Hygiene First: Wash your hands for at least 20 seconds with soap, especially before meals.
