Danish scientists confirmed this week that the new subvariant can reinfect people who’ve previously had omicron, although it doesn’t appear to be all that common.

They also agree that it’s more contagious than the original version of omicron, BA.1, which is still widely circulating around the world.

But it’s surprisingly not driving a second wave of omicron infections. Globally, Covid cases have plunged 21% over the past week.
