CDC study reveals hybrid SARS-CoV-2 spike from Delta/Omicron recombination event

The US Centers for Disease Control and Prevention (CDC) has conducted national-level genomic surveillance to identify and characterize delta-omicron recombinant genomes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). A total of nine genomes with a hybrid delta-omicron spike protein have been identified.
