Public health experts have urged caution, noting that there is as yet no firm evidence that omicron is more dangerous than previous variants like delta, which quickly overtook its predecessors.
New York | First identified in Botswana and South Africa, this new iteration of the coronavirus has prompted concern among scientists and public health officials because of an unusually high number of mutations that have the potential to make the virus more transmissible and less susceptible to existing vaccines.
The World Health Organisation has called omicron a “variant of concern” and on Monday warned that the global risks posed by it were “very high,” despite what officials described as a multitude of uncertainties.
