Flu Activity Surges Across Canada
Recent data reveals a sharp increase in influenza activity across Canada, with the national positivity rate for influenza tests reaching 26.9%, the highest since the 2020-21 season. Older adults, particularly those aged 65 and over, are facing the highest rates of flu detections and hospitalizations. Provinces like Quebec, Prince Edward Island, and British Columbia are seeing especially elevated detection rates. The current flu season is marked by unusual co-circulation of both H3N2 and H1N1 strains, intensifying the severity of the outbreak. Experts warn that the convergence of these two strains is contributing to a dual outbreak scenario. Forecasting models from the AI4Casting Hub project a continued rise in influenza cases, potentially reaching a national positivity rate of 29.5% by mid-March 2025. As Canada navigates this flu season, experts highlight the need for adaptive forecasting and real-time data integration to enhance public health preparedness and response.
