WHO urges cancelling some holiday events over Omicron fears

"An event cancelled is better than a life cancelled" said WHO head Dr Tedros Adhanom Ghebreyesus, adding that "difficult decisions" must be made.

"In some cases, that will mean cancelling or delaying events" he said.

He added that there was now "consistent evidence that Omicron is spreading significantly faster than... Delta".
