Particulars on signs, doable summer time surge
The Facilities for Illness Management and Prevention has detected a brand new set of COVID-19 variants nicknamed FLiRT in wastewater surveillance, in accordance with knowledge from the company.
From April 28 by Might 11, the variant, labeled KP.2, makes up about 28% of the instances in the USA, in accordance with the CDC. That makes it the brand new dominant variant within the nation, overtaking JN.1. The JN.1 variant, which unfold globally over the winter, made up about 16% of COVID-19 instances within the U.S. in the identical two-week span.
KP.1.1, one other FLiRT variant that’s circulating, made up about 7% of COVID-19 instances in that two-week span, in accordance with CDC knowledge.
“The CDC is monitoring SARS-CoV-2 variants KP.2 and KP.1.1, generally known as ‘FLiRT,’ and dealing to higher perceive their potential influence on public well being,” the company stated in an emailed assertion to USA TODAY final week.
“Presently, KP.2 is the dominant variant in the USA, however laboratory testing knowledge point out low ranges of SARS-CoV-2 transmission general at the moment. That implies that whereas KP.2 is proportionally essentially the most predominant variant, it’s not inflicting a rise in infections as transmission of SARS-CoV-2 is low,” the CDC stated within the assertion.
In accordance with the CDC, solely 22.6% of adults reported having obtained an up to date 2023-24 COVID-19 vaccine since September 2023. Knowledge additionally reveals that vaccination protection elevated by age and was highest amongst adults 75 and older.

What are the ‘FLiRT’ variants?
FLiRT is the time period getting used to explain a complete household of various variants, together with KP.2, JN.1.7 and some other variants beginning with KP or JN that seem to have picked up the identical set of mutations, in accordance with Andy Pekosz, PhD, a professor in molecular microbiology and immunology on the Bloomberg Faculty of Public Well being at Johns Hopkins College, in an article posted by the college.
“They’re all descendants of the JN.1 variant that has been dominant within the U.S. for the previous a number of months,” Pekosz stated within the article. “Viruses like SARS-CoV-2 mutate incessantly, and after they mutate to evade recognition by antibodies, this typically weakens their capability to bind to the cells they need to infect. We then see mutations seem that enhance that binding capability.”
Will there be a summer time surge in COVID instances resulting from ‘FLiRT’ variants?
Pekosz stated a summer time surge is definitely doable, and that the FLiRT variants could be excessive on his checklist of viruses that might trigger one other wave of infections within the U.S.
“That stated, our definition of a wave has modified; whereas we nonetheless see case charges rise and fall all year long, we see a lot decrease numbers of instances of hospitalizations or deaths than we noticed within the first couple years of the pandemic,” Pekosz stated within the article.
Pekosz additionally famous that whereas the waves have gotten smaller, they’re nonetheless impacting our inclined populations: the aged, people who find themselves immunocompromised, and people with different secondary medical situations.
Signs of COVID ‘FLiRT’ variant
In accordance with the CDC, there are “no present indicators” that KP.2 would trigger extra extreme sickness than different strains. The company stated it will proceed to watch neighborhood transmission of the virus and the way vaccines carry out towards this pressure.
The “FLiRT” variant reportedly has related signs to these from JN.1 which embrace:
- Fever or chills
- Cough
- Sore throat
- Congestion or runny nostril
- Headache
- Muscle aches
- Problem respiratory
- Fatigue
- New lack of style or scent
- “Mind fog” (feeling much less wakeful and conscious)
- Gastrointestinal signs (upset abdomen, delicate diarrhea, vomiting)
The CDC notes that the checklist doesn’t embrace all doable signs and that signs might change with new variants and may differ by individual.
Typically, the company says, individuals with COVID-19 have a variety of signs, starting from delicate to extreme sickness. Signs might seem two to 14 days after publicity.
Newest COVID steerage from the CDC
In March 2024, the CDC up to date its COVID-19 steerage so individuals who check constructive for the virus will not be directed to isolate at house for 5 days.
Well being officers introduced a brand new coverage specializing in actions individuals can take to scale back spreading quite a lot of frequent respiratory viruses, reminiscent of influenza, respiratory syncytial virus (RSV) and COVID-19. These actions embrace staying house when sick, staying updated with vaccines, practising good hygiene and bettering indoor air high quality.
The change marked the primary time the company has revised its coronavirus tips since 2021. It’s meant for individuals and employers, not for hospitals or nursing properties which have separate steerage, the CDC stated.
CDC officers referred to as the change a streamlined strategy that’s simpler for individuals to know and extra in keeping with circulating respiratory viruses that unfold the identical approach and have related signs.
