BALTIMORE — Another version of the coronavirus is spreading around the globe and causing high rates of COVID-19 infections, along with angst — but also a small measure of optimism.
BA.2, as it’s known, is a subvariant and closely related to the omicron variant that spread rapidly around the world after its discovery in November. Some studies suggest BA.2’s even more transmissible and just as dangerous.
Cases have been found in dozens of countries and are rising rapidly in Denmark and elsewhere, according to the World Health Organization. It’s already been found in at least half of the United States, with Maryland reporting five cases so far in random sampling.
