In a “worst-case scenario,” Gostic said, Delta could transform into something capable of catching up with Omicron, and the two would tag-team. Dual circulation doesn’t just double the number of variants we have to deal with; it “leaves open the possibility for recombination,” a phenomenon in which two coronavirus flavors can swap bits of their genomes to form a nasty hybrid offspring, Ajay Sethi, an epidemiologist at the University of Wisconsin at Madison, told me. (Delta’s brutality + Omicron’s stealth = bad-news bears.) Alternatively, a daughter of Delta may totally overtake Omicron, exacting its ancestor’s sweet, sweet revenge. Or maybe the next variant that usurps the global throne will be a bizarro spawn of Alpha … or something else entirely. In the same way that Omicron was not a descendent of Delta, the next variant we tussle with won’t necessarily sprout from Omicron.
