omicron variant
Highly transmissible strain
The omicron variant is a strain of SARS-CoV-2, the virus causing COVID-19, first identified in late 2021.
Named using the Greek alphabet system for variants, omicron spread rapidly worldwide due to high transmissibility, though it generally caused less severe illness than earlier strains.
The omicron variant drove the winter surge.
