Map of tracked variant occurrence
Circle size proportional to the number of variant genomes, zoom into the region for more detail. Color by recency with red being most recent.
The unique mix of spike amino acid changes in Omicron GR/484A (B.1.1.529) is of interest as it comprises several that were previously known to affect receptor binding and antibody escape. As with all low-frequency variants with potentially relevant changes, these need to be monitored closely to study if they spread more widely as a consequence of an immune escape or altered receptor interactions.
The timely detection of Omicron and immediate sharing of the viral genomes and metadata via GISAID was made possible by the critical contributions from researchers in Botswana, Hong Kong, South Africa
