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; [] structure ...

COVID-19 pandemic. Scientifically accurate atomic model of the external structure of SARS-CoV-2. Each "ball" is an atom.
Variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are viruses that, while similar to the original, have genetic changes that are of enough significance to lead virologists to label them separately. SARS-CoV-2 is the virus that causes coronavirus disease 2019 (COVID-19).
XEC is the latest COVID-19 variant spreading in Europe and the U.S. Infectious disease doctors explain XEC symptoms, treatment, and prevention. ... “It’s one of the Omicron variants and it ...
The XEC COVID variant has spread rapidly in some European countries, and it's now been reported in some U.S. states. But experts said there's no reason to think it poses a new threat.
Here's what we know about how variants like omicron develop and what makes one a "variant of concern." ... including SARS-CoV-2, the virus behind Covid-19, evolve over time. As a virus replicates ...
SARS-CoV-2, the virus that causes COVID-19. The term variant of concern (VOC) for SARS-CoV-2, which causes COVID-19, is a category used for variants of the virus where mutations in their spike protein receptor binding domain (RBD) substantially increase binding affinity (e.g., N501Y) in RBD-hACE2 complex (genetic data), while also being linked to rapid spread in human populations ...
The Omicron subvariants seem like an alphabet soup of letters and numbers. The original Omicron variant was called B.1.1.529. It begat such subvariants as BA.1; BA.1.1; BA.2; BA.2.12.1; BA.3; and ...
