A world map showing confirmed cases of COVID-19 caused by the omicron variant of SARS-CoV-2 as of Feb. 11, 2022, with darker colors indicating higher case counts. The inset is a color-coded map of mutations (yellow, red and green sections) identified in the omicron variant spike protein. A Johns Hopkins Medicine study shows these mutations — that led to the omicron variant — did not help it escape recognition by T lymphocyte immune cells.
