US Flu Season Surges: H3N2 Strain Dominates, Exceeding Last Winter's Epidemic

Current Flu Season Severity

• 📈 Flu cases are on the rise across the nation, with doctors indicating it's already worse than last season.
• ⚠️ The peak of the flu season has not yet been reached, suggesting numbers could continue to climb.
• 🎯 45 states are reporting high to very high levels of the flu.

Dominant Strain: H3N2 Sub-Clade K

• 🦠 Much of the spread is driven by a strain known as H3N2 sub-clade K, which has quickly become the dominant flu virus.
• 🧬 This strain is part of the Influenza A H3N2 family, often linked together during flu season.
• ⚠️ While not appearing to cause more severe illness than typical flu, it is spreading rapidly.

National Impact and Concerns

• 🏥 According to the CDC, there have been at least 4.6 million illnesses, 50,000 hospitalizations, and about 1,900 deaths nationwide.
• 💉 A significant concern is that over 90% of analyzed H3N2 cases involve a newer strain slightly different from the virus targeted by this year's vaccine.
• 👨‍👩‍👧‍👦 The Trump administration is no longer recommending the vaccine for families and children, leaving the decision to families and doctors, a move public health experts fear could further increase numbers.
