Proportion of Omicron Genomes by Week

Genomes are displayed by date of original sample collection. Numerous sub-lineages of the Omicron variant (e.g., BA, BQ, CH, EG) have been characterized. An * indicates additional sub-lineages within that parent lineage. The Omicron other category includes BF, BQ and CH lineages, which comprise less than 10% of all Omicron genomes. Not every positive COVID-19 case is sequenced.
