A variant is just a slightly changed virus, Linda Yancey, M.D., an infectious diseases specialist at Memorial Hermann Hospital says. “Viruses go through generations just like people do.
The first highly publicized variant of the SARS-CoV-2 virus was called alpha (B.1.1.7). The variant began circulating in Great Britain in late 2020. Alpha spread worldwide, including to the U.S ...
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 ...

On January 6, the Centers for Disease Control and Prevention (CDC) announced that it had found at least 52 confirmed cases of the more contagious SARS-CoV-2 variant: 26 in California, 22 in Florida, two in Colorado, and one each in Georgia and New York.

Since then, the omicron virus variant has mutated and given rise to new subvariants. All of the COVID-19 strains that have emerged and gained dominance since 2022 have been descendants of omicron ...
The now-dominant KP.2 and KP.3 variants, which are part of a family of strains collectively referred to as FLiRT variants because of the part of the virus where they have mutated, are subvariants ...
Iota variant, [1] also known as lineage B.1.526, is one of the variants of SARS-CoV-2, the virus that causes COVID-19. It was first detected in New York City in November 2020. The variant has appeared with two notable mutations: the E484K spike mutation, which may help the virus evade antibodies, and the S477N mutation, which helps the virus ...
