“Delta and Omicrom are now twin threats driving up cases to record numbers, leading to spikes in hospitalisation and deaths,” World Health Organization (WHO) director-general Tedros Adhanom Ghebreyesus told a news briefing on Wednesday.

“I am highly concerned that Omicron, being highly transmissible and spreading at the same time as Delta, is leading to a tsunami of cases.” said Tedros.

WHO’s director-general repeated his call for countries to share vaccines more equitably and warned that the emphasis on boosters in richer countries could leave poorer nations short of jabs.

He said the WHO was campaigning for every country to hit a target of 70% vaccine coverage by the middle of 2022, which would help end the acute phase of the pandemic.
