“At this juncture, the XEC variant seems to be the most certainly one to get legs subsequent,” Dr. Eric Topol, founder and director of the Scripps Analysis Translational Institute, posted on X final week. His remarks have been in response to a put up by Mike Honey, a knowledge analyst in Australia who had charted XEC’s origins from Berlin, first showing in June.
XEC’s development in current weeks has been strongest in Denmark and Germany, adopted by the U.Okay. and the Netherlands, Honey’s evaluation reveals. Outbreak.information reported 95 XEC infections worldwide as of Sept. 3, from Canada to Italy to Taiwan, however hasn’t been up to date since. Honey posted Sept. 14 that his knowledge indicated the subvariant had unfold to greater than 500 instances in 27 nations, together with China and Ukraine.

Whereas XEC is on the transfer, its prevalence stays comparatively low within the U.S., in accordance with the Facilities for Illness Management and Prevention (CDC). An Omicron sublineage referred to as KP.3.1.1 (and nicknamed “DeFLuQE”) has just lately taken over, accounting for 53% of infections nationwide from Sept. 1–14, per the CDC’s COVID Knowledge Tracker. XEC isn’t pervasive sufficient to even seem on the tracker—it must account for at the least 1% of infections in a two-week span—however that might not be the case for lengthy.
XEC “may surpass KP.3.1.1 within the coming weeks,” Andrea Garcia, MPH, American Medical Affiliation (AMA) vice chairman of science, medication, and public well being, mentioned within the Sept. 6 episode of the AMA Replace podcast. “There’s not a whole lot of knowledge on this new subvariant at this time limit.”
XEC, in accordance with Topol, is a mixture of Omicron sublineages KS.1.1 and KP.3.3.
What are the signs of XEC an infection?
The CDC has but to pinpoint signs particular to XEC an infection, however pay attention to these typical COVID-19 signs:

Does the brand new COVID vaccine shield towards XEC?
The new 2024–25 COVID vaccines—manufactured by Pfizer, Moderna, and Novavax—arrived sooner than anticipated and are broadly obtainable at pharmacies, well being departments, pressing care facilities, and different well being care suppliers.
The Pfizer and Moderna vaccines are mRNA-based and earmarked for the Omicron KP.2 pressure. The protein-based Novavax vaccine targets its parental lineage, JN.1. Whereas they weren’t engineered to fight XEC per se, they have been manufactured with the household of just lately circulating variants in thoughts.
The CDC recommends everybody aged 6 months and older get an up to date vaccine to guard themselves and their family members towards extreme an infection, hospitalization, and loss of life.

Most U.S. adults are eligible for a free vaccine by their non-public medical health insurance, Medicare, and Medicaid plans, the CDC says.
