What you need to know about FLiRT, an emerging group of COVID-19 variants

Track COVID-19’s new variant, KP.2—more infectious than JN.1—as experts monitor for case increases despite low wastewater infection rates. Stay informed and protected.

The bottom right corner has a logo with "10 almonds" and an image of ten almonds, appealing to those curious about emerging groups and COVID-19 variants.

What you need to know

  • COVID-19 wastewater levels are currently low, but a recent group of variants called FLiRT is making headlines.
  • KP.2 is one of several FLiRT variants, and early lab tests suggest that it’s more infectious than JN.1.
  • Getting infected with any COVID-19 variant can cause severe illness, heart problems, and death.

KP.2, a new COVID-19 variant, is now dominant in the United States. Lab tests suggest that it may be more infectious than JN.1, the variant that was dominant earlier this year.

Fortunately, there’s good news: Current wastewater data shows that COVID-19 infection rates are low. Still, experts are closely watching KP.2 to see if it will lead to an uptick in infections.

Read on to learn more about KP.2 and how to stay informed about COVID-19 cases in your area.

Where can I find data on COVID-19 cases in my area?

Hospitals are no longer required to report COVID-19 hospital admissions or hospital capacity to the Department of Health and Human Services. However, wastewater-based epidemiology (WBE) estimates the number of COVID-19 infections in a community based on the amount of COVID-19 viral particles detected in local wastewater.

View this map of wastewater data from the CDC to visualize COVID-19 infection rates throughout the U.S., or look up COVID-19 wastewater trends in your state.

What do we know so far about the new variant?

Early lab tests suggest that KP.2—one of a group of emerging variants called FLiRT—is similar to the previously dominant variant, JN.1, but it may be more infectious. If you had JN.1, you may still get reinfected with KP.2, especially if it’s been several months or longer since your last COVID-19 infection.

A CDC spokesperson said they have no reason to believe that KP.2 causes more severe illness than other variants. Experts are closely watching KP.2 to see if it will lead to an uptick in COVID-19 cases.

How can I protect myself from COVID-19 variants?

Staying up to date on COVID-19 vaccines reduces your risk of severe illness, long COVID, heart problems, and death. The CDC recommends that people 65 and older and immunocompromised people receive an additional dose of the updated COVID-19 vaccine this spring.

Wearing a high-quality, well-fitting mask reduces your risk of contracting COVID-19 and spreading it to others. At indoor gatherings, improving ventilation by opening doors and windows, using high-efficiency particulate air (HEPA) filters, and building your own Corsi-Rosenthal box can also reduce the spread of COVID-19.

  • Stop Cancer 20 Years Ago

    Dr. Jenn Simmons shares vital tips on preventing cancer and inflammation, advocating for lifestyle changes and proactive health management at any age.

    Get Abreast And Keep Abreast

    This is Dr. Jenn Simmons. Her specialization is integrative oncology, as she—then a breast cancer surgeon—got breast cancer, decided the system wasn’t nearly as good from the patients’ side of things as from the doctors’ side, and took to educate herself, and now others, on how things can be better.

    What does she want us to know?

    Start now

    If you have breast cancer, the best time to start adjusting your lifestyle might be 20 years ago, but the second-best time is now. We realize our readers with breast cancer (or a history thereof) probably have indeed started already—all strength to you.

    What this means for those of us without breast cancer (or a history therof) is: start now

    Even if you don’t have a genetic risk factor, even if there’s no history of it in your family, there’s just no reason not to start now.

    Start what, you ask? Taking away its roots. And how?

    Inflammation as the root of cancer

    To oversimplify: cancer occurs because an accidentally immortal cell replicates and replicates and replicates and takes any nearby resources to keep on going. While science doesn’t know all the details of how this happens, it is a factor of genetic mutation (itself a normal process, without which evolution would be impossible), something which in turn is accelerated by damage to the DNA. The damage to the DNA? That occurs (often as not) as a result of cellular oxidation. Cellular oxidation is far from the only genotoxic thing out there, and a lot of non-food “this thing causes cancer” warnings are usually about other kinds of genotoxicity. But cellular oxidation is a big one, and it’s one that we can fight vigorously with our lifestyle.

    Because cellular oxidation and inflammation go hand-in-hand, reducing one tends to reduce the other. That’s why so often you’ll see in our Research Review Monday features, a line that goes something like:

    “and now for those things that usually come together: antioxidant, anti-inflammatory, anticancer, and anti-aging”

    So, fight inflammation now, and have a reduced risk of a lot of other woes later.

    See: How to Prevent (or Reduce) Inflammation

    Don’t settle for “normal”

    People are told, correctly but not always helpfully, such things as:

    • It’s normal to have less energy at your age
    • It’s normal to have a weaker immune system at your age
    • It’s normal to be at a higher risk of diabetes, heart disease, etc

    …and many more. And these things are true! But that doesn’t mean we have to settle for them.

    We can be all the way over on the healthy end of the distribution curve. We can do that!

    (so can everyone else, given sufficient opportunity and resources, because health is not a zero-sum game)

    If we’re going to get a cancer diagnosis, then our 60s are the decade where we’re most likely to get it. Earlier than that and the risk is extant but lower; later than that and technically the risk increases, but we probably got it already in our 60s.

    So, if we be younger than 60, then now’s a good time to prepare to hit the ground running when we get there. And if we missed that chance, then again, the second-best time is now:

    See: Focusing On Health In Our Sixties

    Fast to live

    Of course, anything can happen to anyone at any age (alas), but this is about the benefits of living a fasting lifestyle—that is to say, not just fasting for a 4-week health kick or something, but making it one’s “new normal” and just continuing it for life.

    This doesn’t mean “never eat”, of course, but it does mean “practice intermittent fasting, if you can”—something that Dr. Simmons strongly advocates.

    See: Intermittent Fasting: We Sort The Science From The Hype

    While this calls back to the previous “fight inflammation”, it deserves its own mention here as a very specific way of fighting it.

    It’s never too late

    All of the advices that go before a cancer diagnosis, continue to stand afterwards too. There is no point of “well, I already have cancer, so what’s the harm in…?”

    The harm in it after a diagnosis will be the same as the harm before. When it comes to lifestyle, preventing a cancer and preventing it from spreading are very much the same thing, which is also the same as shrinking it. Basically, if it’s anticancer, it’s anticancer, no matter whether it’s before, during, or after.

    Dr. Simmons has seen too many patients get a diagnosis, and place their lives squarely in the hands of doctors, when doctors can only do so much.

    Instead, Dr. Simmons recommends taking charge of your health as best you are able, today and onwards, no matter what. And that means two things:

    1. Knowing stuff
    2. Doing stuff

    So it becomes our responsibility (and our lifeline) to educate ourselves, and take action accordingly.
