ECDC: Sars-CoV-2 : Variants of Concern (VOC) 8.9.2022

https://www.ecdc.europa.eu/en/covid-19/variants-concern

Variants of Concern (VOC)

For these variants, clear evidence is available indicating a significant impact on transmissibility, severity and/or immunity that is likely to have an impact on the epidemiological situation in the EU/EEA. The combined genomic, epidemiological, and in-vitro evidence for these properties invokes at least moderate confidence. In addition, all the criteria for variants of interest and under monitoring outlined below apply.

All sub-lineages of the listed lineages are also included in the variant, e.g., BA.1.1 is included in Omicron BA.1 as it is a sub-lineage of BA.1.
