ByBrian “Weence” Bateman

Seattle, WA – March 14, 2026 – Washington has confirmed 26 measles cases this year, more than double 2025’s total, as health officials track spread and hospital trends.

Washington health officials report that measles activity continues to rise statewide, with 26 confirmed cases so far in 2026 — already more than double the 12 cases recorded in all of 2025. The increase marks the state’s first outbreak since 2023 and has prompted renewed monitoring across the Seattle area.

Measles Cases Outpace Last Year

According to the Washington State Department of Health, the 26 confirmed cases this year represent a significant jump compared to last year’s total. Recent reporting indicates that many of the 2026 cases are linked to in-state transmission rather than travel alone.

State officials have emphasized that measles remains highly contagious and are continuing case investigations and exposure notifications where appropriate. Health agencies note that outbreaks are not considered over until six weeks have passed since the last confirmed case.

Regional and National Context

Nationally, the United States has surpassed 1,100 measles cases in 2026, adding to concern about renewed spread. Washington’s outbreak is being tracked alongside activity in other states as public health departments monitor vaccination coverage and community transmission patterns.

For Seattle-area residents, the increase comes as the region continues to manage seasonal respiratory illnesses. The state’s Respiratory Illness Data Dashboard, updated March 11, shows ongoing monitoring of hospital bed use tied to COVID-19, influenza, and RSV, alongside outbreak reporting for other notifiable conditions such as measles.

What Residents Should Know

Public health guidance continues to stress the importance of staying current with recommended vaccinations and checking official exposure notices if cases are reported in specific locations. Schools, childcare providers, and healthcare facilities follow established protocols for notification and exclusion when needed.

Residents can review measles case updates and respiratory illness trends through the Washington State Department of Health website and local public health agencies.

If you have urgent symptoms, seek medical care. For general questions, talk with a licensed clinician.
