England’s chief medical officer Chris Whitty confirmed Saturday that a new coronavirus strain which surfaced in the country could spread faster and called for greater public vigilance to reduce transmission.
Whitty said London had informed the World Health Organization of its findings.
Health Secretary Matt Hancock on Monday said scientists had identified a “new variant” in the south of England that could be causing infections to spread faster.
Britain has seen rising cases and hospital admissions this month and Prime Minister Boris Johnson was set to give a press conference on the virus situation on Saturday afternoon.
The prime minister was reportedly to announce new travel restrictions for London and southeast England in the run-up to Christmas.
“As a result of the rapid spread of the new variant, preliminary modelling data and rapidly rising incidence rates in the South East (an expert body advising the government) now consider that the new strain can spread more quickly,” Whitty said.
“We have alerted the World Health Organization,” he said, but added: ‘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 warned that the new evidence made it “more vital than ever” that the public did all they could to reduce transmission.
