Global Emergence and Spread of the XFG SARS-CoV-2 Variant and Its Clinical Profile Among XFG Patients in Maharashtra, India
The XFG variant emerged as the dominant SARS-CoV-2 lineage globally during late 2024-2025 and circulated widely across India, with a brief mid-2025 surge. Despite reduced clinical severity, XFG's rapid spread and diversification highlight ongoing viral adaptability and the need for strengthened, complementary surveillance to detect emerging variants early.
