spreading in Europe, the XEC COVID variant—and cases have been spotted in the U.S., too.

“The XEC variant appears to be the most likely one to get legs next,” Eric Topol, M.D., founder and director of the Scripps Research Translational Institute, recently wrote on

The World Health Organization (WHO) has not yet publicly profiled XEC, but the Scripps COVID-19 epidemiology tracker

has sequencing information on the variant, which is already getting attention for how contagious it appears to be.

So, what is the XEC COVID-19 variant and how concerned about it should you be? Infectious ******** doctors break it down.

What is the XEC variant?

The XEC variant is a new COVID-19 variant that’s been tracked around the world. “It’s one of the Omicron variants and it seems to be reasonably contagious,” says

that widely circulated this summer.)

XEC has several mutations on the spike protein, which is what SARS-CoV-2 (the virus that causes COVID-19), uses to latch onto your cells and infect you. As a result, it may be more infectious than other recent strains.

“Like every SARS-CoV-2 variant that appears—and will appear, in perpetuity—the spread is related to evolution of the virus to develop new mutations that allow it get around some of the immunity engendered by prior infections and vaccinations,” says infectious ******** expert

Where has the XEC variant been detected?

The XEC variant is currently more common in Europe. Right now, it’s been

in Poland, Norway, Luxembourg, Ukraine, and Portugal. But XEC has also been spotted in China, and there have been 23 cases in the U.S. so far, including three in California.

“I anticipate that, if it is a more fit version of SARS-CoV-2, it will likely dominate most countries,” Dr. Adalja says. “However, the time scale will be different in each country.”

XEC COVID-19 variant symptoms

XEC is still a newer COVID-19 variant and, with that, there have been no new symptoms reported. These are the biggest symptoms of COVID-19, according to the

, but that shot was formulated based on the KP.2 strain of the virus. KP.2 is related to XEC, but there are a lot of differences between them.

“It’s unclear how the updated vaccine will fare against this variant,” Dr. Adalja says. “But, based on the biological characteristics of XEC, it is not likely to be a good match and will not provide durable protection against infection.” That said, Dr. Adalja stresses that the vaccine will still “protect high-risk individuals against severe ********.”

But if you’re an otherwise healthy person and levels of the virus are lower in your area, he says that “October is an excellent

But Dr. Adalja also recommends keeping in mind that COVID-19 isn’t going anywhere, making it important to be prepared that you’ll interact with it at some point. “This is an endemic respiratory virus and will always be present,” he says.
