Do you plan to get your flu vaccine earlier this year than in previous years?
Respiratory illness cases are increasing across Washington state as influenza circulates earlier than in previous years. Emergency room visits for the virus have been on the rise since late August.
Why it matters
The earlier onset of flu season suggests an unpredictable winter for respiratory health in the region. Monitoring these trends is essential as the state prepares for potential later surges in virus variants.
Public Health Seattle and King County reports 233 flu-related emergency room visits for the week ending September 19, 2026. This figure marks a significant increase from the 31 cases recorded during the same period in 2025.

The details
Flu cases are being identified through emergency room visits reported by local health authorities. While mRNA-based vaccines and take-home nasal mists are available, public health officials are watching the early spike closely.
Timeline
June 2025: The Advisory Committee on Immunization Practices was dissolved.
Late August 2026: Emergency room visits for influenza began to rise.
September 19, 2026: The data reporting week recorded 233 flu-related ER visits.
December or January: These months typically mark the peak of the flu season.
Health Landscape
The dissolution of the Advisory Committee on Immunization Practices in June 2025 has altered the oversight of national vaccine protocols. This administrative change complicates the landscape for managing public health responses to early seasonal outbreaks.
Residents should be aware that flu activity is appearing earlier this year, which may necessitate earlier consultation with healthcare providers. Available preventative options include mRNA-based influenza vaccines and take-home nasal mist alternatives.
The takeaway
The early rise in influenza cases highlights the importance of staying current with available preventative measures like vaccines. Residents should remain vigilant for potential late-winter surges in both flu and COVID-19 cases.
