Understanding Influenza A as Self-Care

This year’s influenza season is shaping up to be one of the most intense in recent memory. Across the United States, flu activity has climbed sharply, with hospitalizations nearly doubling in a single week and more than 7.5 million illnesses already reported. This year (2025-2026 season), the dominant Influenza A strain causing concern is a rapidly evolving H3N2 virus.  The fast-spreading H3N2 subclade is driving much of the surge, spreading quickly through communities and overwhelming hospitals.

While experts note that the new strain isn’t necessarily more severe on an individual level, the sheer speed and scale of transmission, coupled with rapid genetic changes, mean more people are getting sick and requiring hospitalization. Over 3,100 deaths have already been recorded this season, including pediatric cases, and flu activity remains “high” or “very high” across much of the country. The CDC estimates that over 81,000 Influenza-related hospitalizations have occurred to date. With the season still climbing toward its peak, the risk of infection is real, and prevention matters more than ever. The good news is that there are straightforward, evidence-based steps everyone can take to reduce their risk.

Five Practical Ways to Protect Yourself

1. Get vaccinated as soon as possible. Even if the vaccine isn’t a perfect match for the circulating strain, it still reduces the severity of illness and lowers the risk of hospitalization.

2. Stay home when sick — and encourage others to do the same. This year’s rapid spread is fueled in part by people pushing through symptoms. Resting at home protects your community and speeds your recovery.

3. Mask in crowded indoor spaces. With transmission rising quickly, masking in high-density settings (airports, concerts, clinics) adds a valuable layer of protection.

4. Improve indoor air quality. Use HEPA filters when possible, increase ventilation, and avoid poorly ventilated spaces during peak flu activity.

5. Practice consistent hand hygiene. Wash hands frequently, avoid touching your face, and keep sanitizer accessible — especially after being in public spaces.

Influenza A is hitting hard and fast this season, but we’re not powerless. A combination of vaccination, smart precautions, and community awareness can dramatically reduce the spread. As cases continue to rise, now is the time to double down on prevention and protect the vulnerable people around us.
