California health officials have confirmed the spread of a mutated influenza strain known as the “super flu,” as flu-related hospitalizations across the state reach their highest level of the season.

The California Department of Public Health (CDPH) said Jan.15 that the strain, a mutated form of seasonal influenza A known as H3N2 subclade K, is present in the state. The announcement comes as the department confirmed a second pediatric death linked to the flu since the start of the current respiratory virus season.

State data show flu activity has eased slightly from a late-December peak. As of Jan. 3, about 15% of flu tests statewide were positive, down from 17% recorded through Dec. 27. Despite the modest decline, hospitalizations have continued to rise.

Flu-related hospital admissions reached a season high of approximately 3.8 per 100,000 people statewide as of Jan. 3, according to CDPH figures.

Public health officials continue to emphasize vaccination as the most effective way to reduce the risk of severe illness, even when circulating strains differ from those targeted by the vaccine.

“Current seasonal flu vaccines remain effective at reducing severe illness and hospitalization, including the currently circulating viruses,” said Dr. Erica Pan, CDPH director and state public health officer, said in a statement.

Pan added that “it is important for families to know that flu vaccines, tests, and treatments remain widely available for all Californians and that it is not too late to get a flu vaccine.”

Health officials urge residents to seek medical care if flu symptoms worsen and to take preventive measures as flu season continues across California.
