CDC Manitoba Hepatitis A Notice Adds a Health Check for Canada Trips

The U.S. Centers for Disease Control and Prevention has added Manitoba, Canada, to its travel health notice list because of an ongoing hepatitis A outbreak, giving American travelers a fresh reason to review vaccination status and basic food, water and hand-hygiene precautions before crossing the border this summer.

The notice is classified as Level 1, the CDC's lowest travel health category, which means travelers are advised to practice usual precautions rather than avoid the destination or cancel plans. Still, the timing matters for U.S. travelers because summer is peak season for cross-border road trips, outdoor travel, family visits and regional events across Canada, and health notices can affect how travelers prepare even when they do not change the trip itself.

CDC says Manitoba is currently experiencing a hepatitis A virus outbreak. The agency describes hepatitis A as a contagious, vaccine-preventable liver infection that can spread through close person-to-person contact or through contaminated food or drink. The CDC guidance tells travelers to make sure they are vaccinated against hepatitis A, wash hands carefully, avoid sharing needles or other drug equipment, practice safer sex and seek medical care if symptoms develop during or after travel.

What Changed for Travelers

The practical change is not a border restriction. It is a pre-trip health reminder from the U.S. public health agency most American travelers and travel advisors use for destination health guidance. The CDC page was last reviewed on June 4, 2026, and lists the notice under Canada because the outbreak is concentrated in Manitoba.

Canadian reporting and Manitoba public health updates indicate the outbreak has been significant. Global News reported that Manitoba had recorded 784 outbreak-associated hepatitis A cases as of June 4, up from 658 on May 6. The same reporting cited 165 hospitalizations, eight intensive-care admissions and four deaths since the outbreak began. Manitoba officials have said the outbreak initially affected northern communities and has since spread more widely in the province, including cases in Winnipeg.

Manitoba's chief provincial public health officer, Dr. Brent Roussin, told Global News that the CDC notice was not intended to discourage travel. His point is important for U.S. readers: this is a warning to prepare, not a signal that Manitoba is closed to visitors.

Why It Matters for the U.S. Travel Market

Canada is one of the easiest international trips for Americans, and Manitoba is a common destination for travelers heading to Winnipeg, northern outdoor areas, family visits, business trips, sporting events and road itineraries across the central provinces. A Level 1 CDC notice will not stop most travel, but it can change the checklist for travelers, travel advisors and tour operators.

For consumers, the key question is simple: are you protected against hepatitis A before you leave? For travel sellers and group planners, the issue is communication. Trips that involve older travelers, people with chronic liver disease, immunocompromised travelers, children, extended stays, volunteer work, remote communities, shelters, correctional facilities or close contact with local communities may require more careful pre-trip guidance.

The CDC says people over 60, people with chronic liver disease and people with weakened immune systems face higher risk of severe disease. That does not mean those travelers should automatically cancel, but it does mean they should speak with a health professional before departure if they are not already vaccinated or if they may have had a recent exposure.

What U.S. Travelers Should Do Before Going

Americans planning Manitoba travel should treat the notice as a prompt to check health documents alongside passports, flight times and hotel confirmations. The most useful steps are straightforward:

• Review hepatitis A vaccination status well before departure, especially for travelers who have not previously been vaccinated.
• Ask a clinician or travel clinic about vaccine timing or post-exposure options if a possible exposure has already occurred.
• Wash hands thoroughly before eating or preparing food and after using the bathroom, caring for someone who is ill or changing diapers.
• Be more cautious with food and drink hygiene in situations where sanitation may be uncertain.
• Watch for symptoms after travel, including dark urine, clay-colored stools, diarrhea, fatigue, fever, joint pain, appetite loss, nausea, abdominal pain or jaundice.

The CDC says post-exposure prophylaxis should be given as soon as possible and ideally within two weeks of exposure for people who have not previously received hepatitis A vaccine. That is another reason travelers should not wait until they feel ill to ask questions if they believe they were exposed.

Flights, Airports and Ground Plans Still Matter

For travelers flying into Manitoba, Winnipeg James Armstrong Richardson International Airport remains the main gateway. Travelers can use Odyssey's Winnipeg airport guide and YWG live flight board to track arrivals and departures, especially if they are coordinating with relatives, rental cars or tour departures after landing.

Ground planning also matters because some travelers may be heading beyond Winnipeg into smaller communities or longer road itineraries. Odyssey's Winnipeg airport transfers and taxi guide and YWG car rental guide can help travelers think through the first leg of the trip before they focus on the health checklist.

The Bottom Line

The CDC's Manitoba hepatitis A notice is not a reason for most U.S. travelers to abandon Canada plans. It is, however, a fresh reminder that health preparation is part of cross-border travel, even for nearby destinations that can feel routine. For Americans headed to Winnipeg or elsewhere in Manitoba this summer, the safest approach is to verify hepatitis A protection, follow hygiene guidance and monitor official CDC and Manitoba public health updates before departure.
