'Super Flu' Threatens Christmas: Mutated H3N2 Spreads Rapidly in US, UK, Canada

• A mutated H3N2 influenza A variant, "subclade K" or "super flu," is rapidly spreading across the US, UK, and Canada, raising concerns about a severe flu season.
• Symptoms are similar to seasonal flu but appear faster, including fever, cough, body aches; severe signs like difficulty breathing require immediate attention.
• Experts warn the new variant may be more adept at evading immunity from vaccines and previous infections, potentially leading to more widespread illness.
• High-risk groups include young children, older adults, pregnant women, and those with underlying health conditions.
• Preventive measures include vaccination, handwashing, avoiding crowds, staying home when sick, and considering masks in crowded indoor settings.

Why It Matters: A mutated "super flu" (H3N2 subclade K) is spreading globally, urging vigilance and preventive action.
