The Case for Kraken
A new subvariant of SARS-CoV-2 is rapidly taking over in the U.S.—the most transmissible that has ever been detected. It’s called XBB.1.5, in reference to its status as a hybrid of two prior strains of Omicron, BA.2.10.1 and BA.2.75. It’s also called “Kraken.”Not by everyone, though. The nickname Kraken was ginned up by an informal group of scientists on Twitter and has caught on at some—but only some—major news outlets.
