WHO says authorities investigating new COVID-19 variant in England

GENEVA -- The World Health Organization is aware of a new variant of COVID-19 that has emerged in Britain, but there is no evidence the strain behaves differently to existing types of the virus, it said on Monday.

"We are aware of this genetic variant reported in 1,000 individuals in England," the WHO's top emergencies expert Mike Ryan told a news briefing in Geneva.

"Authorities are looking at its significance. We have seen many variants, this virus evolves and changes over time."

England's Chief Medical Officer Chris Whitty stressed there was no evidence that the variant is more dangerous, infectious or able to evade testing.

He also cautioned against blaming it for the spike in cases across the country's southeast.

"The variant may or may not be contributing to that," Whitty said at a press conference, adding: "We don't know what's cause and effect."

Andrew Davidson, reader in virology at Bristol University, said coronaviruses are known to mutate, have done elsewhere in Europe and North America, and were not always more virulent.

"However, if they spread more easily but cause the same disease severity, more people will end up becoming ill in a short period of time," he said.

Jeremy Farrar, director of the Wellcome Trust, said it was not yet clear how the variant would affect the first vaccines and treatments.

"The surveillance and research must continue and we must take the necessary steps to stay ahead of the virus," he added. --Reuters with Agence France-Presse
