A little more than two weeks since omicron’s discovery a lot has been learned about the latest coronavirus variant. A lot remains to be discovered.

Early data from South Africa, the epicenter so far, shows that the virus appears to spread far faster than earlier strains but also doesn’t appear to be causing severe disease.

Nothing is definitive yet, so the world is still somewhat in the dark. With omicron cases doubling every few days in the U.K. and spreading in other places, policymakers and investors are grasping at any clues.
