As H3N2 sweeps across Canada, what to know about flu’s heart attack risk
  • The H3N2 influenza strain is currently sweeping across Canada, leading to an increased risk of heart attacks and strokes, as highlighted by data published in the Journal of the American Heart Association. This surge in flu cases has raised alarms among health officials, particularly as hospitalizations have nearly doubled in recent weeks.
  • The implications of this development are significant for public health, as the H3N2 strain is known for causing more severe symptoms and complications, particularly among vulnerable populations such as children and the elderly.
  • This situation reflects a broader trend of increasing flu severity, with similar patterns observed in the U.S., where the H3N2 virus is also spreading rapidly. The rise in cases underscores the importance of vaccination and public health measures, especially as the holiday season approaches and gatherings increase.
