📈 What’s Changing?

The 2024–2025 respiratory season is showing unexpected shifts in the timing and intensity of common viruses:

• 🟡 Influenza (Flu): More prevalent, peaking at 23.2% positivity. Outbreaks occurred earlier and spread more widely.
• 🔵 COVID-19: No major winter surge. Fewer hospitalizations compared to previous years. Still present but not overwhelming healthcare systems.
• 🟠 RSV: Later onset than usual. Pediatric cases remain high despite delayed peak.

🔍 Why These Changes?

• Changes in community immunity from vaccinations and previous infections
• Behavioral factors such as masking, travel, and school reopening
• Environmental conditions like temperature and humidity
• “Viral competition“: viruses can suppress or delay each other’s spread

📊 What This Means for You

• Stay up-to-date with all recommended vaccinations (flu, COVID-19, RSV)
• Expect seasonal illnesses to come at unusual times
• Those at higher risk (elderly, young children, immunocompromised) should stay vigilant throughout the season
