Right here’s much more cause to get a flu shot: This 12 months’s flu season is predicted to be a foul one, probably even worse than final 12 months’s record-breaking season.
Final 12 months was the worst flu season in 15 years for america, with excessive hospitalizations and an infection ranges.
“We also saw the highest number of pediatric flu deaths that we’ve seen since 2009-2010,” mentioned Dr. Robert Hopkins, the medical director of the Nationwide Basis for Infectious Ailments.
Nobody desires a repeat of final flu season, however we could also be on monitor for that. Right here’s what to know:
Flu season is off to a foul begin within the U.Ok., and specialists suppose that might occur right here, too.
In accordance with BBC reporting, specialists within the U.Ok. predict the nation may have a extreme flu season, too, based mostly on an early begin to the flu season there, together with a mutation within the flu virus. This isn’t excellent news for respiratory virus season anyplace, together with within the U.S.
“We do generally see similar patterns in North America, as we see in Western Europe,” mentioned Dr. Daniel Kuritzkes, the chief of the division of infectious ailments at Brigham and Girls’s Hospital in Boston. “So, it is likely that we’ll see a similar flu season here to what’s being experienced currently in the U.K.”
Derek Smith, the director of the Centre for Pathogen Evolution on the College of Cambridge, instructed the BBC that mutations within the H3N2 flu pressure are inflicting a “fast increase” in circumstances.
Primarily based on the newest information from the Facilities for Illness Management and Prevention, the H3N2 pressure is within the U.S., too, and is at present essentially the most “frequently reported” influenza virus within the nation.
“It has undergone some changes and some mutations, a fairly significant number of mutations, so … it is likely to cause a problem,” mentioned Dr. Jill Foster, a professor on the College of Minnesota Medical College.
“The flu virus that is circulating does appear to be more pathogenic. It is more easily transmitted, and when transmitted, causes more severe disease,” Foster mentioned.
And if COVID has taught us something, it’s that viruses don’t keep inside nation borders, Foster famous.
To foretell the severity (or not) of flu season within the U.S., specialists glean influenza information from international locations within the Southern Hemisphere, the place the flu season happens throughout our summer time months (Australia, for instance, had a document excessive variety of flu circumstances this 12 months), together with European international locations, the place flu season begins slightly earlier.
Flu season has additionally began early in Japan and Canada, Hopkins added. “You put that together with the reports of these mutations in the H3N2 influenza that were detected back this summer, all are concerning for potentially a second severe flu season in the U.S. in a row,” Hopkins defined.
Foster agreed. “All of that leads you to a place of saying that it is likely that we are going to have a worse flu season.”

The excellent news, for now, is that flu charges within the U.S. are at present low.
The CDC updates flu exercise weekly, however that wasn’t taking place for a lot of the autumn due to the federal government shutdown. Now, although, that information is again on-line.
Particular person states additionally monitor sicknesses, however the stage of monitoring varies. When taking a look at state-by-state information, together with in his personal state of Massachusetts, flu charges are additionally not but elevated, Kuritzkes mentioned.
Hopkins agreed. “Based on the city and state level surveillance … cases appear to be fairly low and similar to the same time the last couple of seasons.”
This doesn’t imply there’s no flu within the U.S., although. Southern states and states together with Arizona and New York are beginning to see a small uptick in flu circumstances, based on epidemiologist Caitlin Rivers’ Substack.
“We’re not seeing any surge in cases so far, which would suggest that if we are going to look like what England is looking like, there’ll be a lag,” Kuritzkes mentioned. Within the U.S., circumstances don’t improve an excessive amount of till December after which are inclined to peak in January or February, with a second peak in March.
Flu pictures shield folks from extreme outcomes like hospitalization and demise.
Annually, the flu vaccine is up to date to supply the very best safety towards the flu strains which can be anticipated to be dominant that season, however this new flu virus pressure emerged after specialists chosen the strains for the present 12 months’s flu vaccine, Hopkins mentioned.
That means, this 12 months’s flu vaccine doesn’t match this new, mutated virus pressure.
“It is certainly concerning that a new strain has emerged that seems to be somewhat divergent from the strain against which the vaccines were selected,” Kuritzkes mentioned.
However that doesn’t imply the vaccine isn’t essential. It stays one of the best ways to guard your self. “Even if the vaccine is not a perfect match, there are many reasons that people should get the flu vaccine if they haven’t done so already,” Kuritzkes famous.
Boosting your flu immunity could not imply you received’t get contaminated with the flu this winter, however in case you do, “it’s likely that the flu you get will be less severe than if you’re unvaccinated,” based on Kuritzkes.
Roughly 89% of youngsters who died of flu in 2024-2025 weren’t absolutely vaccinated, which reveals the significance of the safety that vaccination provides.
Final flu season, solely about 47% of adults obtained a flu shot within the U.S. Information for this 12 months isn’t but obtainable (once more, due to the shutdown), however Foster is nervous about what vaccine hesitancy might imply for shot uptake.
“There’s been so much confusion and so much disarray in pushing out vaccine recommendations this year that I would not at all be surprised to see that flu vaccine uptake in this country is less this year than usual, and if it is, then we’re really in trouble,” Foster mentioned.
Unvaccinated persons are extra prone to die or find yourself within the hospital from flu and usually tend to have extreme illness that spreads to others for longer, Foster added.
“Second, even if [H3N2] is the most concerning one, there are typically several strains that circulate,” Kuritzkes mentioned. Simply because the vaccine isn’t an ideal match for the brand new pressure doesn’t imply it received’t be for future flu strains, added Kuritzkes.
Whereas it’s simple to panic over headlines about an upcoming extreme flu season, Hopkins mentioned to organize as an alternative of panic.
“Make sure that you have fever-reducers around the house, make sure that you keep plenty of fluids around the house, get some over-the-counter COVID and flu tests, so that if you are sick, you can test and let your health care professional know what you got,” Hopkins defined.
There are antiviral drugs your physician can prescribe for flu (and COVID) that may assist cut back the severity of your sickness.
To guard your self and others, wash your arms often, cough or sneeze into your sleeve — and, when you’ve got children, encourage them to do the identical. Sporting a masks in crowded indoor areas can even shield you from the flu, together with different viruses.
“Let’s do the things we can to reduce our risk for either giving or getting any of these viruses,” Hopkins mentioned.
Infants and older adults are most in danger for extreme outcomes from the flu, so take additional care if you’re round people in these age teams, Foster mentioned.
“I think it’s important that we recognize we’re all in this together. When I think about protection against any of these viruses, I think about not only protecting myself and my family, but I also think about the people around me,” Hopkins mentioned. “If we prevent illness in our community, we reduce the likelihood that we’re going to get ill, and we reduce the impact on our community and on our health care workers around us.”
This story has been up to date to replicate the latest CDC flu information, which was initially unavailable on the time of publishing.
