Mutated influenza strain spreading internationally may take off in California

Thursday, November 27, 2025 -Health authorities are warning that a mutated influenza strain, already spreading internationally, could gain a foothold in California as flu season intensifies. 

Early reports suggest the strain may be more contagious than typical seasonal flu, prompting increased surveillance and preparedness measures.

Public health officials are urging residents to get vaccinated, practice good hygiene, and remain alert for symptoms. Hospitals and clinics are reviewing capacity and response plans to handle potential surges in flu cases, especially in vulnerable populations such as the elderly and immunocompromised.

Epidemiologists emphasize that while the strain is concerning, early interventions and widespread vaccination can help limit its impact. Authorities continue to monitor international developments closely, seeking to prevent the virus from overwhelming local healthcare systems.
