Flu Season Intensifies in Alaska, Idaho, Oregon, and Washington

The U.S. Centers for Disease Control and Prevention (CDC) is continuing to monitor elevated levels of seasonal influenza activity across the nation, as detailed in the FluView surveillance report #4.

The CDC's in-season severity assessment framework classified the 2025-2026 flu season as moderate across all ages.

As of February 6, 2026, the CDC reports that influenza activity remains high nationally, although some areas are seeing stabilization or a decline in flu cases.

Most regions are reporting stable or decreasing overall flu activity.

However, influenza activity is still on the rise, with high infection rates driven by an influenza A(H3N2) strain in HHS Region 10, which includes the Pacific Northwest states: Alaska, Idaho, Oregon, and Washington.

The CDC emphasizes that getting vaccinated is a crucial preventive measure, even late in the current flu season, as it significantly reduces the risk of severe illness, hospitalization, and death.

The CDC strongly advises those who have not yet been vaccinated to do so as soon as possible. Various flu vaccines are still available at local clinics throughout the USA.

Approximately 134 million doses of influenza vaccine have been distributed in the United States this season.
