Influenza-related illnesses killed 36 Alaskans during the 2025-2026 flu season, which ran from October through July. This total reflects a significant increase in deaths compared to the 25 recorded in the 2024-2025 season and 10 in the 2023-2024 season.
Why it matters
The increased severity of the 2025-2026 season was driven by a combination of concentrated viral transmission, low vaccination rates, and specific characteristics regarding virus and vaccine effectiveness. This trend follows several years where flu illnesses and deaths were nearly eliminated.
Only 22.7% of Alaskans aged 19 and older received a flu vaccination during the 2025-2026 season. Officials currently recommend annual flu shots for all residents aged six months and older.

Alaska Section of Epidemiology
This state agency is responsible for monitoring public health trends and issuing vaccination recommendations for residents.
The details
Flu cases in Alaska have been climbing steadily since mid-August 2026, following a noted spike in infections during November. The state saw a consistent upward trajectory in mortality rates over the last three flu seasons after reaching near-zero levels during 2020, 2021, and 2022.
Timeline
2020-2022: Flu illnesses and deaths were almost entirely eliminated in Alaska.
2023-2024 season: 10 Alaskans died from influenza-related illnesses.
2024-2025 season: 25 Alaskans died from influenza-related illnesses.
2025-2026 season: 36 Alaskans died from influenza-related illnesses.
Mid-August 2026: Influenza cases began to rise in Alaska.
Health Landscape
The rise in recent flu deaths marks a departure from the 2020-2022 influenza suppression period observed in the state. This shift underscores the difficulty in maintaining low transmission levels as behavioral patterns and population immunity change over time.
Because only 22.7% of adults were vaccinated, residents are encouraged to prioritize annual flu shots for all family members over six months old to reduce severe outcomes. Staying updated on immunization can help mitigate the risks posed by concentrated viral transmission.
The takeaway
The recent increase in flu-related mortality suggests that immunity levels have shifted significantly since the previous low-transmission years. Residents should consult with healthcare providers to understand the importance of vaccination as a primary defense against seasonal respiratory illness.
