You may remember the XBB variant that took Singapore by storm last fall—one of the most immune-evasive yet. Dubbed “Gryphon” by the Canadian biology professor Ryan Gregory—who has a lot more names like it for other variants—after the mythical amalgamation of eagle and lion, it’s less of a global player than it was then. Now its descendants are battling for dominance throughout the world. Experts are keeping a close eye in particular on (the also Gregory-monikered) “Kraken” XBB.1.5, due to its ability to grow at a breakneck pace.
A recent report out of India offers some comfort, however. Of 85 patients with XBB variants surveyed in Maharashtra, India, during the later half of 2022, most (88%) were symptomatic, but the majority of them (79%) were able to cope with infection at home, versus in a hospital. The study (which has not yet been peer reviewed) also had good news about survival and symptoms.
