UK Prime Minister Boris Johnson on Saturday announced a series of stricter coronavirus restrictions, tightening rules around household mixing that were due to be relaxed over Christmas in London and southeast England.
The PM broke the news Saturday that London and the southeast of England, where cases are surging, will go into Tier 4 restrictions, similar to a lockdown, on Sunday.
"The spread is being driven by the new variant of the virus," Johnson said in a hastily called press conference. "It appears to spread more easily and may be up to 70% more transmissable than the earlier strain."
England's chief medical officer, Professor Chris Whitty, warned Saturday that a newly identified variant of Covid-19 "can spread more quickly" than previous strains of the virus.
"This is now spreading very fast," Johnson warned. "It is with a very heavy heart that I say we cannot continue with Christmas as planned."
Johnson outlined that in areas under the toughest restrictions, there will be no possibility for household mixing over Christmas. In areas under Tier 3, mixing will now be restricted to Christmas Day.
As recently as this week, Johnson reiterated his pledge to relax rules over the Christmas period, allowing up to three households to mix for five days. But as of Saturday, the entire nation is being asked not to travel and those under the highest level of restrictions, will not be allowed to travel abroad except for work purposes.
According to Whitty, the new variant is responsible for 60% of infections in London, which have nearly doubled in the last week.
Earlier, he said "urgent work" is underway to establish whether the new strain, prevalent in the southeast of England, can cause a higher mortality rate.
"There is no current evidence to suggest the new strain causes a higher mortality rate or that it affects vaccines and treatments although urgent work is underway to confirm this," Whitty said in a statement.
As with other new variants or strains of Covid-19, this one carries a genetic fingerprint that makes it easy to track, and it happens to be one that is now common. That does not mean the mutation has made it spread more easily, nor does it not necessarily mean this variation is more dangerous.
Multiple experts in the genetics and epidemiology of viruses are noting that this one could be just a "lucky" strain that's been amplified because of a superspreader event; it could be the mutation somehow makes it spread more easily without causing more serious illness; or it could just be by chance.
The government's scientific advisory group for Covid-19 has also warned the new strain is a "real cause for concern," and called for urgent action. On Twitter, Jeremy Farrar said, "Research is ongoing to understand more, but acting urgently now is critical. There is no part of the UK & globally that should not be concerned. As in many countries, the situation is fragile."
Whitty also urged people to take more precautions. "Given this latest development it is now more vital than ever that the public continue to take action in their area to reduce transmission," he said.
