Rare flu complication rose in recent years

Reports of children in the United States with influenza-associated encephalopathy or encephalitis (IAE) increased from none during the 2020-2021 flu season to a preliminary 14% for the 2024-2025 season, based on a new analysis from the Centers for Disease Control and Prevention (CDC). IAE involves a range of neurologic syndromes triggered by flu infection of the respiratory tract, with diagnosis based on brain lesions detectable on imaging, wrote Amara Fazal, MD, and colleagues at the CDC’s National Center for Immunization and Respiratory Diseases. A series of anecdotal reports of pediatric cases with IAE in January 2025 prompted the CDC’s investigation; the findings were published in the Morbidity and Mortality Weekly Report (MMWR).
