Manitoba is experiencing a hepatitis A outbreak that has resulted in four fatalities and prompted a travel alert from the U.S. Centers for Disease Control and Prevention (CDC). The CDC issued a Level 1 alert, indicating a heightened transmission rate but not advising against travel to the province. The alert serves as a reminder of the contagious nature of hepatitis A, which can cause acute liver infection. As of June 4, Manitoba has reported 784 hepatitis A cases since the outbreak began in April 2025, with 165 hospitalizations, including eight in intensive care. The outbreak has primarily affected northern communities, but cases are increasingly being reported in Winnipeg, particularly among individuals experiencing homelessness.
Why It Matters
This situation highlights the ongoing public health challenges posed by contagious diseases like hepatitis A, particularly in vulnerable populations. The outbreak in Manitoba is notable for its scale, with the province accounting for a significant portion of Canada’s hepatitis A cases. Public health officials emphasize the importance of vaccination and safe hygiene practices to prevent further spread. Additionally, Manitoba is currently facing a measles outbreak, which further complicates the public health landscape and raises concerns about vaccine-preventable diseases in the region.
