First flu-related death of the season confirmed in Snohomish County

Snohomish County has confirmed its first flu-related death of the 2025-2026 flu season.

According to the Snohomish County Health Department, a woman in her 60s died Saturday after testing positive for influenza A — the most common and severe type of flu. The woman also had underlying health conditions.

In the last flu season, the first flu death didn’t occur until January. Flu activity usually peaks between December and February.

“With the Thanksgiving holiday just around the corner, it’s a perfect time to get your annual flu shot,” Dr. James Lewis, a health officer for the Snohomish County Health Department, said. “It’s a good idea to get vaccinated at least one to two weeks before a family gathering. This gives your body enough time to build up immunity and offer protection.”

During last year’s influenza season, Snohomish County reported 53 flu-related deaths, the most in more than a decade, according to the Snohomish County Health Department. Additionally, 859 flu-related hospitalizations were reported.

“It is a bit concerning to have our first death so early in the season,” Lewis added. “Things will only get worse.”

Nine influenza-related hospitalizations have occurred so far this season, as of this reporting. The health department stated that it’s too early to predict the severity of this season.

People who are at higher risk for severe disease from influenza include young children, older adults, people who are immunocompromised or have chronic health conditions, pregnant individuals, and those residing in long-term care facilities or nursing homes.

The annual flu vaccine is recommended for everyone ages six months and older.
