Flu season has officially kicked off, and there’s a new strain causing concern. The Influenza A H3N2, specifically its subclade K variant, has been linked to a notable increase in cases globally, including in the U.S.
Dr. Neil Mania, a public health professor at Northeastern University in Boston, shared insights about this variant during a recent conversation. He emphasized the severity of this new strain, stating, “It’s becoming clear that this is a fairly severe variant of influenza. In various regions worldwide where it’s been noticed, it’s resulting in significant illness already, and we’re seeing the beginning of a flu epidemic.”
This particular variant differs from earlier influenza strains, presenting intensified symptoms such as fever, chills, fatigue, cough, sore throat, and runny nose. According to Mania, subclade K represents a “perfect storm” this flu season, especially since vaccination rates are generally declining. Notably, the current flu vaccines don’t specifically target this variant.
“Getting vaccinated is crucial, but this year’s vaccine doesn’t perfectly match the variant, which likely adds to the severity of cases,” he explained. “We’re heading into this season facing a variant with lower vaccination rates that appears to be more aggressive.”
With growing apprehension about the flu season, Mania noted, “There’s considerable concern that this will be a particularly challenging flu season regarding the number of cases and their seriousness.” He also mentioned that this variant offers less natural immunity within the community, further exacerbating the potential for spread and severe illness.
Health professionals point out that individuals who haven’t been vaccinated are at a higher risk of hospitalization and experiencing more severe symptoms. Alongside vaccination, they advise frequent handwashing, highlighting the risk of various illnesses, which may linger on surfaces for extended periods.
The holiday season poses additional risks, as gatherings and crowded transportation can facilitate exposure to those who are sick. Mania encouraged people to stay home if they are unwell, pointing out that this simple act can help prevent the spread of illnesses, including influenza, norovirus, and COVID-19.
If someone is unsure about their health or symptoms, consulting a healthcare provider for testing is recommended. Providers may also be able to prescribe medications to help lessen the severity and duration of illnesses.
Ultimately, it’s vital for everyone to remain alert and prioritize their health and that of their families this season.
