WASHINGTON (AP) — Flu is rising rapidly across the U.S., driven by a new variant of the virus — and cases are expected to keep growing with holiday travel.
That variant, known as “subclade K,” led to early outbreaks in the United Kingdom, Japan and Canada. In the U.S., flu typically begins its winter march in December. On Tuesday, the Centers for Disease Control and Prevention reported high or very high levels of illness in more than half the states.
The CDC estimated there have been at least 7.5 million illnesses, 81,000 hospitalizations and 3,100 deaths from flu so far this season. That includes at least eight child deaths — and is based on data as of Dec. 20, before major holiday gatherings.
Some states are particularly hard-hit. New York’s health department said the week ending Dec. 20 marked the most flu cases the state had recorded in a single week since 2004: 71,000.
It’s far too soon to know if this flu season will be as severe as last winter’s.
But it’s not too late to get a flu shot, which health experts say can still prevent severe illness even if someone gets infected. While this year's vaccine isn't a perfect match to the subclade K strain, a preliminary analysis from the U.K. found it offered at least partial protection, lowering people's risk of hospitalization.
According to the CDC, only about 42% of adults and children have gotten a flu vaccination so far this year.
The flu virus is a shape-shifter, constantly mutating, and it comes in multiple forms. There are two subtypes of Type A flu, and subclade K is a mutated version of one of them, named H3N2. That H3N2 strain is always harsh, especially for older adults.
Subclade K’s mutations aren’t enough of a change to be considered an entirely new kind of flu.
But they’re different enough to evade some of the protection from this year’s vaccine, said Andrew Pekosz, a virus expert at Johns Hopkins Bloomberg School of Public Health.
The CDC said it’s too soon to know how severe this season will be.
Flu seasons dominated by any version of H3N2 tend to be bad, with more infections overall and more people becoming seriously ill. But Hopkins’ Pekosz cautioned it will take time to tease apart whether this subclade K version simply spreads more easily or also is more dangerous.
That question aside, the CDC notes there are some prescription medicines to treat flu — usually recommended for people at high risk of complications. But they generally need to be started a day or two after symptoms begin.
The CDC and major medical societies all recommend a flu vaccine for just about everyone age 6 months and older. Despite lots of recent misinformation and confusion about vaccines, the flu recommendations haven’t changed.
Flu is particularly dangerous for people 65 and older, pregnant women, young children and people of any age who have chronic health problems, including asthma, diabetes, heart disease and weak immune systems.
The vaccines are brewed to protect against three influenza strains. Despite concern over that new H3N2 variant, they appear to be a good match against H1N1 and Type B flu that may also circulate this year, Pekosz said.
There are shots for all ages, as well as the nasal spray FluMist for ages 2 to 49. For the first time this year, some people may be eligible to vaccinate themselves with FluMist at home.

SIOUX FALLS, S.D. (AP) — Easter is around the corner, and it's time to start thinking about how to decorate your eggs.
Whether you're dying eggs for your table spread or planning to hide them for an egg hunt, it's important to follow food safety guidelines to minimize germs and maximize your egg quality.
Eggs are remarkably long lasting, so there needn't be a giant rush to eat them.
“Stores usually do turn over eggs pretty quickly, so the recommendations is you should consume eggs three to five weeks after you purchase them,” said Kara Lynch, food safety educator with Michigan State University Extension.
There is also a benefit in letting eggs age just a bit, as older eggs can be easier to peel. That's because eggs shrink over time within the shell, creating an air pocket between the egg and the shell.
Egg processors clean eggs before they reach store shelves, but it also is important to thoroughly cook eggs to reduce the risk of foodborne illness, especially salmonella. That bacteria lives naturally in the gastrointestinal and reproductive tracts of chickens, said Kimberly Baker, associate extension specialist at Clemson University.
To cook your eggs, place them in a saucepan, fill it with water and bring it to a boil. After that, put the lid on, turn the heat off and let it sit for about 12 minutes. Some also favor turning down the heat and simmering eggs.
You can vary the time in the hot water depending on a desire for harder boiled or slightly creamier eggs, but the yolk should be pretty solid to be safe. Boiling them for too long can risk creating green sulfur development on the outside of the yolk.
After that, Don Schaffner, food science department chair at Rutgers University, said there are two options.
You can run your eggs under cold water to reduce the temperature. From there, you can color them right away or place them back in the fridge until you're ready. Or, after you've boiled them, you can let them air dry until they've cooled.
The boiling process sanitizes the eggs, and as long as they are kept out of water, Schaffner said, they will remain safe to eat.
“You’ve boiled the egg, you’ve gotten rid of any bacteria that might be in the egg. And now you’ve air-cooled it, right? So it’s going to cool more slowly, it’s probably going to cook more,” he said. “But most importantly, you don’t have to worry about any bacteria from the water getting internalized into the egg.”
Either artificial or natural food dye is OK as long as the dye label says it's food grade. For those keeping track, the U.S. Food and Drug Administration has been updating its guidance and regulations regarding certain dyes.
And no, it's not a problem if the dye seeps through the shell.
“Eggs kind of naturally have their own abilities to absorb only so much,” Baker said.
As you're decorating the eggs and have the eggs outside, she suggested keeping your eggs in an ice bath, so they can stay at a cooler temperature while you're decorating.
Eggs should generally be kept at or below 40 degrees (4.4 degrees Celsius) to minimize the risk of contaminants.
Cooked eggs that weren't air-cooled should spend no more than two hours at room temperature. And that's cumulative, including the time spent decorating and the time spent hiding during the Easter egg hunt.
But if it's particularly warm, then that two-hour rule may be shortened to one hour, Lynch said.
Hard boiled eggs are generally good for about a week in the fridge.
Be careful with your eggs as you handle them.
One of the biggest concerns is making sure your eggs haven't cracked during an Easter egg hunt, making them vulnerable to contaminants. And once the egg has been hard boiled, there's no way to kill bacteria that get inside, Baker said.
“We don’t want to be putting them in the soil or in lawns where pets have gone to the bathroom,” she said.
Whether the eggs are hidden outdoors or in a corner of your home, you should rinse them in cool water before you peel them. And wash your hands, too, just in case the eggs have picked up something.
If the Easter egg hunt means your eggs will be at room temperature for longer than two hours, experts recommended using plastic eggs for the hunt instead of real ones to minimize food safety risk.
“If it’s an outdoor Easter egg hunt at any time, I would say go with the plastic eggs and be safe,” Baker said. “And use your dyed Easter eggs as your centerpiece on your table or your buffet, and enjoy them that way.”
