Supercharged mutant Covid strain is 'probably already in the US and may even have started here', scientists warn

THE mutant strain of the coronavirus detected in Britain could already be circulating in the US and may even have originated in the country, scientists have said.

The new strain, thought to be up to 70 per cent more infectious than the original, was first detected in London earlier this month and has now been identified in at least six other territories around the world.

The news prompted Prime Minister Boris Johnson to cancel a planned relaxation of coronavirus restriction over Christmas, and some 40 countries have now imposed bans on UK flights.

The US has so far not followed suit, although on Monday Assistant Secretary for Health Brett Giroir said that "everything [is] on the table".

Speaking to CNBC last night, Dr. Scott Gottlieb, a former head of the Food and Drug Administration, was asked if a travel ban could stop the new strain spreading to the US.

"I think this is already in the US," he said.

"I don't think that a travel ban at this point is going to prevent this mutated strain from coming in to the United States.

"We're going to have an epidemic that continues to build over the course of the next three or four weeks… and then we'll start to see infection rates decline as we see vaccinations get rolled out."

Cases of the new strain have so far been identified in Denmark, Italy, the Netherlands, Gibraltar, and Australia, and there have been unverified reports of cases in Belgium.

  • Turkey: Flights from the UK, along with South Africa, Denmark and the Netherlands have been suspended.

As an alternative to a UK ban, officials on the White House's coronavirus task force have discussed requiring all arrivals from the UK to present a negative Covid test, CNN reports.

Dr. Gottlieb added: “As the virus continues to spread around the world, we’re going to start to see more of these variants, and that’s why it’s important to get the population vaccinated and snuff out these infections.

“The more infections you have, the more chances that these variants start to propagate.”

Speaking at a press conference yesterday, New York governor Andrew Cuomo voiced support for a travel ban, though added that he believed "intuitively [the new strain] is already here".

Top White House medical adviser Dr Anthony Fauci also said yesterday the new strain could already be circulating in the US.

“It very well might be here for all we know. That’s why we have a system to do surveillance," he said.

Speaking to the Washington Post, Jeremy Luban, a virologist at the University of Massachusetts Medical School, added: "It may have even started here."

He said that the strain might be present but not have been identified in the US because the country's sequencing program is "so sporadic".

Angela Rasmussen, a virologist at the Georgetown Center for Global Health Science and Security, echoed concerns that the new strain has probably already entered the country.

“It makes sense that it was detected first in the U.K. because they have probably the world’s best surveillance program," she said.

"It would not shock me at all to find out that it also is circulating in the U.S."

The US has seen over 18.4million cases of coronavirus since the start of the pandemic, almost a quarter of the global total.
