- Flu cases are trending upwards across the country.
- Subclade K is becoming the dominant flu strain in the U.S.
- The current flu vaccine is still considered a good match for the circulating strains.
- Simple preventative measures like handwashing and isolation can help limit spread.
The flu is officially back, folks. And it’s not just *a* flu—it’s a new player on the field. “We are really starting to get into flu season. All of the indicators, all of the surveillance points to us are trending upwards. The Subclade K is showing up more and more as they’re testing the flu specimens as they come in,†explained Roberta Sturm, the director of Communicable and Environmental Diseases and Emergency Preparedness at the knox County Health Department.
Is the current flu vaccine effective against Subclade K? While the variant was identified after this year’s vaccine was developed,health officials assure the public that the current vaccine is still providing protection. “The flu vaccine is still,from what I understand,a very good match,and that does tend to help decrease rates of hospitalization and duration of illness,†Sturm said.
So far, the flu season is tracking similarly to previous years in terms of hospitalizations and overall illness rates, despite the emergence of this new variant. It’s notable to remember that the flu virus is constantly evolving, and mutation is a normal part of its lifecycle, according to Sturm.
Knowing the difference between a cold and the flu is crucial. If you experience a fever alongside a sore throat and cough, it’s best to consult a doctor or get tested for the flu.
And there’s still time to get vaccinated! Sturm emphasized that it’s never too late to receive the flu shot and benefit from its protective effects. Beyond vaccination, she highlighted simple yet effective strategies for staying healthy.
“Wash your hands frequently,†Sturm advised. “If you are sick, and you’re living in a household with other individuals, isolate yourself as much as you can. Doesn’t hurt to throw on a mask … when you’re coughing to limit those droplets from being spread around the house.â€
