Massachusetts Records Eighth Pediatric Flu Death Amid Ongoing Seasonal Outbreak

Massachusetts health authorities have reported the eighth pediatric influenza-related death this season, raising the state’s total influenza fatalities to 306, per the Department of Public Health (DPH). This includes 298 adult deaths, the second-highest toll in the past eight years. The 2024-2025 flu season, which recorded 470 total deaths in Massachusetts, remains the deadliest since the H1N1 pandemic, according to state records.

Pediatric fatalities have drawn attention from health experts, as most affected children were unvaccinated. The CDC noted 90 U.S. pediatric deaths from influenza this season, with 85% of cases involving unvaccinated individuals. In Massachusetts, the most recent pediatric death occurred during the week of February 15, 2026. The week of December 28 to January 3 saw the highest seven-day death toll, with 52 fatalities, including three children.

The current flu season’s severity is linked to the A H3N2 subclade K variant, which differs from this year’s vaccine strain and has contributed to increased hospitalizations and deaths, particularly among older adults. While officials note the overall season appears less severe than the previous year, the presence of this variant highlights the importance of vaccination.

Dr. Robbie Goldstein, the state’s public health commissioner, stressed the role of flu vaccinations in reducing viral impact. In a January statement, he stated, ‘These viruses are serious, dangerous, and life-threatening. We are seeing children who are seriously ill, families grieving losses, and hospitals facing capacity strain.’ He urged vaccination as a way to protect communities. The DPH continues to recommend annual flu shots for individuals 6 months and older, despite recent federal guidance that has adjusted recommendations for children.

The 2025-2026 season follows the 2024-2025 season, which saw 470 total influenza deaths in Massachusetts, including 10 pediatric fatalities—a sharp rise from the prior two seasons, which recorded 251 and 235 deaths, respectively. The current season’s lower death toll may reflect reduced severity of the subclade K variant and ongoing public health measures to limit virus spread.

Health officials also emphasized monitoring influenza-like illness (ILI) activity, which remains elevated. As of late February, influenza-related hospitalizations accounted for 1.13% of total hospitalizations, down 0.2% from the prior week, while ILI visits reached 2.94%, slightly above the baseline of 2.2%. These metrics suggest the flu season is beginning to wane, but vigilance is necessary to prevent further spread.

The DPH continues to track the situation through its influenza dashboard and promote vaccination and preventive measures, especially among unvaccinated populations. Officials will assess the subclade K variant’s impact and adjust strategies as the season progresses.
