A new COVID-19 XFG has been detected in 163 cases across India, according to INSACOG. The variant's immune evasion traits could pose challenges if it spreads in the coming months. XFG is a recombinant subvariant of the SARS-CoV-2 virus, and it is formed by the mixing of two earlier variants. Scientists say LF.7 and LP.8.1.2 have combined to form XFG.
