SARS-CoV-2 Alpha variant: Variant of SARS-CoV-2, the virus that causes COVID-19
Alpha variant, also known as lineage B.1.1.7, is a variant of SARS-CoV-2, the virus that causes COVID-19. One of several variants believed to be of particular importance, it is estimated to be 40%–80% more transmissible than the wild-type SARS-CoV-2 and was detected in November 2020 from a sample taken in September, during the COVID-19 pandemic in the United Kingdom; it began to spread quickly by mid-December, and is correlated with a significant increase in SARS-CoV-2 infections in the country. This increase is thought to be at least partly because of one or more mutations in the virus's spike protein. The variant is also notable for having more mutations than normally seen.
