Flu activity across the United States has been on the rise, and health officials from the Centers for Disease Control and Prevention (CDC) are warning that this trend could persist for several weeks. Dr. Carrie Reed, chief of the epidemiology and prevention branch of the CDC’s influenza division, emphasized the current prevalence of the virus during a recent interview, stating, “There’s a lot of influenza out there right now.”
The CDC’s latest estimates reveal that the ongoing flu season has led to at least 11 million illnesses, 120,000 hospitalizations, and 5,000 deaths. Dr. Reed noted that these figures are likely underreported, as the CDC usually presents a conservative estimate of flu activity.
Adding to the complexity of the situation is the emergence of a new variant known as subclade K, which has become the dominant strain this season. This variant, a mutation of the H3N2 subtype of influenza A, has raised concerns due to its differences from the components included in the current flu vaccine. Among the 994 flu samples tested since the end of September, nearly all were influenza A, with approximately 90% identified as H3N2.
While the current vaccine may not provide a perfect match against subclade K, health officials still encourage annual vaccinations. Dr. Reed reassured the public that the vaccine is expected to confer some level of protection, reducing the risk of severe disease, hospitalization, and death despite the virus’s mutations. Importantly, she noted that the new variant has yet to cause a significant increase in severe illnesses.
For individuals who do contract the flu, antiviral medications are available that can help alleviate symptoms and shorten the duration of illness. Health experts advise those at higher risk for severe complications to seek medical attention promptly and consider antiviral treatments.
With the flu season still in full swing, health officials are encouraging anyone who has not yet received a flu shot to do so. “There’s still time to get a flu vaccine,” Dr. Reed reiterated, highlighting that while it takes a few weeks for immunity to build after vaccination, the ongoing flu activity presents an opportunity for individuals to benefit from the protection that the vaccine offers.
In light of the current flu landscape, it is essential for the public to remain vigilant, get vaccinated, and take any necessary precautions to protect themselves and their communities.
