Flu activity across the United States is likely to remain elevated for several more weeks, according to a senior epidemiologist at the Centers for Disease Control and Prevention.
Millions Sick So Far This Season
The CDC estimates at least 11 million flu illnesses nationwide so far, along with about 120,000 hospitalizations and 5,000 deaths. Officials say those figures are likely undercounts based on early data.
New Variant Becomes Dominant
A newer strain known as subclade K has become the dominant variant this season. It is part of the H3N2 influenza A virus and has mutations that make it somewhat different from recent strains and the current vaccine.
Vaccine Still Recommended
Despite the mismatch, health experts stress that the flu vaccine still provides meaningful protection, particularly against severe illness, hospitalization and death. The CDC continues to recommend annual vaccination for nearly everyone 6 months and older.
No Sign of Increased Severity Yet
CDC officials say the new variant has not yet been linked to more severe disease, though trends are being closely monitored as flu activity continues.
Treatment Options Available
Antiviral medications are available for people who get sick, especially those at higher risk for complications. When taken early, antivirals can shorten illness and reduce the risk of severe outcomes.
Not Too Late to Get Vaccinated
Health officials emphasize that it’s still worthwhile to get a flu shot, noting that flu season often extends into the spring and vaccination can still offer protection in the weeks ahead.
