Why Flu season started earlier than expected what to know about the brand new vaccine
Every influenza cycle behaves differently, but the 2026 season has brought unexpected geographical shifts. Traditionally, the flu begins picking up momentum in the southern states before spreading northward.
This year, the virus appeared first on the West Coast, hitting states like California, Washington, Hawaii, and Alaska incredibly early. Many epidemiologists suggest these regional changes might point to an evolving virus adapting to new environments.
| Indicator | Historical Average | 2026 Season Data |

| Activity Spike Month | October to November | Late August |
