CDC reports early rise in influenza activity across the U.S

The Centers for Disease Control and Prevention (CDC) reports that influenza activity is increasing earlier than usual this year. While national seasonal influenza activity remains low, several surveillance indicators have been trending upward since late August and early September 2026.

Key indicators showing increases include the percentage of specimens testing positive for influenza, outpatient visits for influenza-like illness (ILI), emergency department visits with influenza discharge diagnoses, and laboratory-confirmed influenza-associated hospitalizations. Currently, Louisiana is the only state reporting moderate flu activity, though officials note this could change rapidly.

Health experts recommend regular handwashing and receiving annual flu shots as primary defenses. High-risk groups, including young children, pregnant women, adults over 65, and individuals with weakened immune systems, are advised to take extra precautions. Improving indoor air quality with HEPA filters is also recommended to help remove airborne particles.
