Scientists racing to gauge the threat of omicron
The omicron variant is set to spread quickly throughout the United States, health experts warn, but what will happen after that is still less certain, as the severity of the variant is still in question.
Omicron has spread twice as fast as the delta variant in South Africa; 200,000 people are becoming infected with omicron every day in Britain; and in Denmark, omicron cases are doubling roughly every two days.
Early data from the United States suggests that Americans will see nothing different, though delta remains the dominant variant nationwide. Roughly 120,000 new COVID cases are being reported daily, a 40% increase from two weeks prior.
But omicron could soon surpass these numbers, with the share of cases caused by omicron increasing to 2.9% from 0.4% in just a week, according to data from the federal Centers for Disease Control and Prevention.
