Watch: WHO expects more Omicron data 'within days'
The WHO said it expects to have more information on the transmissibility of the Omicron variant within days.
Maria van Kerkhove, WHO technical lead on COVID-19, said the schedule was faster than the "weeks" they had predicted it would take to assess data after designating it a "variant of concern", its highest rating.
She said one possible scenario was the new variant, which was first reported in southern Africa, could be more transmissible than the dominant Delta variant.
Van Kerkhove said it was not yet known if Omicron makes people more ill.
On Thursday, a government minister suggested larger businesses may consider cancelling their staff Christmas parties amid fears over the dangers posed by Omicron.
Business minister George Freeman told the BBC: “It slightly depends on the nature of the business. For many small businesses, four or five staff, who are working together every day anyway, gathering to have a drink isn’t a big step up in risk.
“But some companies might normally bring hundreds of people in from around the world to a big party, and they may decide, this year, is that sensible given the pandemic and given where we are?
“In the end, I think business people know how to make those decisions. The Government has set out clear guidance.”
Freeman said he has cancelled his in-person Christmas party with staff this year and is instead planning a proper gathering in the spring.
His comments came the day after the prime minister urged people to carry on as normal with their Christmas plans.
