The SARS-CoV-2 variant XFG, nicknamed "Stratus," is a recombinant descendant of the Omicron JN.1 lineage. Formed by combining genetic features from subvariants like LF.7 and LP.8.1.2, XFG features increased transmissibility and moderate immune evasion, though it does not cause more severe disease than previous Omicron strains
