The Omicron variant of the coronavirus is spreading faster than the Delta variant and is causing infections in people already vaccinated or who have recovered from the COVID-19 disease, the head of the World Health Organization (WHO) said on Monday.
“There is now consistent evidence that Omicron is spreading significantly faster than the Delta variant,” WHO director-general Tedros Adhanom Ghebreyesus told a news briefing for Geneva-based journalists, held at its new headquarters building.
“And it is more likely people vaccinated or recovered from COVID-19 could be infected or re-infected,” Tedros said.
