Timeline of the SARS-CoV-2 Omicron variant

This timeline of the SARS-CoV-2 Omicron variant (November 2021 – February 2022) is a dynamic list, and as such may never satisfy criteria of completeness. Some events may only be fully understood and/or discovered in retrospect.

The extensive mutations of its spike proteins make for the Omicron variant. Mutation data from WHO;^[1] structure from PDB: 6VYB.^[2]
