New Flu Strain Hits Children Hard
12 Feb
Summary
- Influenza B strain is increasing, especially affecting children.
- This year has seen 22 million cases and 12,000 deaths, including 60 children.
- Seven states report the highest levels of flu activity.

A concerning rise in influenza B cases is being observed across several U.S. states, with children appearing to be disproportionately affected. This strain of the flu, while similar to influenza A, can cause more severe symptoms in younger individuals, including seizures, vomiting, and diarrhea.
Nationwide, flu activity has been significant this season, with 22 million cases and 12,000 deaths reported to date. Tragically, 60 children have succumbed to the illness. The Centers for Disease Control and Prevention data from late January indicated that influenza B comprised nearly a quarter of tested cases, a notable increase as the season typically peaks in late winter.
As of February 12, 2026, seven states are reporting the highest levels of flu activity: Oregon, Arkansas, Kansas, Louisiana, Missouri, South Carolina, and Tennessee. Health officials warn that flu activity is not over and could lead to further waves of infection. Vaccination remains the most effective measure to protect against severe illness, as approximately 90 percent of flu-related deaths this year have occurred among unvaccinated individuals.
