A new subvariant of COVID-19 that has been spreading all through Europe not too long ago made its manner into the USA, and specialists consider it might drive one other wave of infections within the coming months.
The XEC subvariant was first recognized in Germany in June and has since unfold to a few continents and dozens of different international locations, together with the UK, Denmark, Poland, Ukraine, and now the USA. Eric Topol, MD, a board-certified heart specialist and the director of the Scripps Analysis Translational Institute, instructed the Los Angeles Times XEC is “simply getting began.”
Dr. Topol took to X to supply his insight on the rising variant, suggesting it “seems to be the almost certainly one to get legs subsequent.” However with its presence within the U.S. hardly detectable proper now, many questions on the way it will really have an effect on an infection charges stay.
Right here’s we learn about XEC to this point:

1. It’s a subvariant of Omicron
Dr. Topol says XEC is a mixture of established subvariants KS.1.1 and KP.3.3, each of which have been circulating for a number of months. KP.3.3 is carefully associated to KP.3, one of many FLiRT variants that has been accountable for almost all of COVID instances reported since early August.
All of those are subvariants of the Omicron variant, which was first detected in 2021 and has been the dominant coronavirus variant worldwide for a number of years now.
2. XEC seems to unfold shortly
Since XEC was first recognized in June, infections brought on by the subvariant have elevated quickly all through August and early September, indicating that the subvariant may very well be extra contagious than others which have circulated not too long ago. Final week, XEC instances elevated 16 p.c in Denmark and 17 p.c in Germany. With the info being about one week behind and with faculties now being again in full swing, it’s seemingly these figures will quickly rise within the U.S. as properly, Dr. Topol suggests.
Associated Tales
Consultants are estimating that XEC’s presence is rising at a faster tempo than JN.1—the variant that dominated final winter and spring and continues to indicate up within the Facilities for Illness Management and Prevention (CDC)’s variant tracker. Though XEC has been detected within the U.S., it isn’t but registering on the official tracker. In keeping with Scripps COVID-19 epidemiology tracker Outbreak.info, 23 instances of XEC had been confirmed within the U.S. heading into Labor Day weekend. At the least three of these had been in California.
At the moment, KP.3.1.1 accounts for over half of all COVID instances within the U.S. The following closest subvariant circulating is KP.2.3, with 12 p.c of instances. Based mostly on information from Europe, experts are forecasting XEC to overhaul KP.3.1.1 within the U.S. over the subsequent a number of weeks.
3. Signs are acquainted
Up to now, experiences from across the pond point out XEC’s signs mirror these associated to colds, flus, and different strains of COVID—the commonest appear to be fever, aches, sore throat, and cough.
4. The brand new COVID boosters ought to provide safety towards XEC
Vaccine makers develop their merchandise figuring out COVID will proceed to mutate, however with the hope that the shot will nonetheless present safety towards an infection and severe sickness. Each Pfizer and Moderna not too long ago rolled out their newest COVID boosters, that are tailor-made to the KP.2 subtype. Consultants have signaled XEC is said carefully sufficient to KP.2 that the most recent vaccines ought to present not less than some safety towards the subvariant.
“The lab research, which have been very predictive previously, give us each purpose to be assured that what’s within the vaccines now will certainly defend us through the winter,” William Schaffner, MD, beforehand instructed Nicely+Good.
The suggestions for who ought to get these photographs haven’t modified. The CDC recommends everybody ages six months and older get vaccinated towards COVID, however it’s particularly necessary for people who find themselves 65 and older, at excessive threat for a extreme case of the virus, or immunocompromised.
As we’ve seen with earlier waves of COVID, instances are prone to develop as temperatures cool and folks collect indoors extra typically. Whereas we don’t know for certain how XEC will unfold, we do know that tried-and-true measures—like regular handwashing, staying house when sick, masking up in crowded settings, and getting vaccinated—assist cut back the unfold of any virus.
