WHO said, a rapid growth of Omicron could result in large numbers of hospitalisations, particularly amongst unvaccinated groups, and cause widespread disruption to health systems and other critical services.
Some 11,500 flights have been scrapped worldwide since Friday, and tens of thousands more delayed, during one of the year’s busiest travel periods.
