The study provides evidence of intervariant and intravariant recombination of rapidly evolving SARS-CoV-2 genomes, suggesting potential for more infectious, immune-escaping, and disease-causing Omicron and Delta-Omicron variants.
Among numerous severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concerns, Omicron is more infectious and immune-escaping, while Delta is more pathogenic. Here, we provide evidence for both intervariant and intravariant recombination of the rapidly evolving new SARS-CoV-2 genomes, including XD/XE/XF and BA.3, raising concerns of potential more infectious, immune-escaping, and disease-causing Omicron and Delta-Omicron variants.
