Here’s what we know about the new European coronavirus mutation



“I don’t think there should be any reason for alarm right now,” Adm. Brett Giroir, who has been in charge of testing, told George Stephanopoulos on ABC’s “This Week.”

Variations to the virus are nothing new, and experts say the novel coronavirus does not mutate as much as influenza, meaning it is less likely that a vaccine would need to be developed every year to keep up with the new strains.

Still, much about this variant remains unknown, such as whether it is a new strain — a functionally different version of the virus.

“The take-home message for right now is that we need to get more information,” said Krutika Kuppalli, an infectious-diseases specialist at the Medical University of South Carolina. “In the meantime, we all need to really double down on our public health measures — wearing masks, remaining physically distanced, avoiding crowds of people.”

Where has the variant been detected?

In September, U.K. researchers discovered the variant’s prevalence when they collected samples from infected people in southeastern England. It seemed to spread quickly.

“This lineage came up quite rapidly,” Nick Loman, one of the researchers and a professor of microbial genomics at the University of Birmingham, told The Washington Post.

Since then, Australia, Denmark and the Netherlands have identified cases of the variant in their countries, the World Health Organization told the BBC. On Sunday, Italian officials announced that a patient returning from Britain “in the last few days” was in isolation after scientists detected the mutation.

In South Africa, health officials said Sunday that a version of the virus similar to the U.K. variant has been found in 80 to 90 percent of samples analyzed since mid-November.

Is the variant already in the United States?

The virus has not been detected in the United States, but officials are watching for developments in Britain, Giroir told Stephanopoulos.

Although guidance from federal agencies discourages traveling to Britain, the United States has not banned travel from there.

“I really don’t believe we need to do that yet,” Giroir said.

But New York Gov. Andrew M. Cuomo (D) pointed out Sunday that it would take only one flight to the United States to spread the mutation, urging federal officials to restrict travel.

“Right now, this variant in the U.K. is getting on a plane and flying to JFK,” Cuomo said on a conference call with reporters.

However, Kuppalli warned that little is known about the effectiveness of a ban, referring to instances in which people rushed to airports and congregated in long lines trying to travel before restrictions were put into effect earlier in the pandemic.

It is also not entirely certain whether the virus gained its foothold in the southeast of England because of its altered genetic markers or through super-spreading events, said Scott Gottlieb, a former head of the Food and Drug Administration.

“It seems like this new strain is more contagious,” Gottlieb said on CBS’s “Face the Nation.” “It doesn’t seem to be any more virulent, any more dangerous than run-of-the-mill covid. The next question is: Will it obviate our natural immunity?”

Will the authorized vaccines still be effective against this variant of the virus?

As of now, experts say there has been no indication that the variant is resistant to the Pfizer and Moderna vaccines authorized by the FDA.

“There is no reason to believe that the vaccines that have been developed will not be effective against this virus as well,” Vivek H. Murthy, President-elect Joe Biden’s nominee for surgeon general, told host Chuck Todd on NBC’s “Meet the Press.” “The bottom line is if you’re at home and hearing this news, it does not change what we do in terms of precautions.”

Although the vaccine remains out of reach for most Americans, following guidance such as social distancing and wearing masks remains the most practical way to prevent transmission.
