The world is on high alert due to the new omicron Covid strain — but delta is still responsible for most of the current infections globally, the World Health Organization pointed out on Monday.
"Over 99% of cases around the world are due to the delta variant and more deaths are occurring in the unvaccinated," WHO Chief Scientist Soumya Swaminathan told CNBC's "Squawk Box Asia" on Monday. "I think that's our priority while we wait to find out more about [the omicron] variant."
Last week, the global health agency recognized the omicron variant, first referred to as lineage B.1.1.529, as a variant of concern. That means it could be more contagious, more virulent or more skilled at evading public health measures, vaccines and therapeutics. The strain was first identified by South African scientists.
