'I wouldn't call it super flu' but 'it is more severe,' says doctor: How to get through the rest of this flu season
The flu has infected "significantly" more Americans this winter than usual, says a doctor and infectious disease specialist.
TL;DR
- At least 20 million Americans have contracted the flu this season, resulting in 270,000 hospitalizations and 11,000 deaths.
- The dominant strain, influenza A (H3N2) subclade K, is responsible for 90% of infections and is considered more severe than in prior seasons.
- Reduced vaccine effectiveness, due to unexpected viral mutations, and a significant drop in flu vaccinations (a record low since 2019 for children) are contributing factors.
- Vaccine effectiveness is estimated at 70-75% for kids and 30-40% for adults, still offering significant protection.
- It is not too late to get a flu shot, especially for children, parents, urban dwellers, and those in multi-generational households.
- Masking and social distancing are recommended to reduce transmission, particularly for those with mild symptoms or sick children.
- High-risk groups, including older adults, young children, pregnant individuals, and those with certain health conditions, should take extra precautions.
- Antiviral treatments like Tamiflu are available and can be prescribed by a doctor.
- Key symptoms distinguishing the flu from a cold include fever, cough, intense body aches, and fatigue, with severe body aches being a strong indicator of the flu.
