SARS-CoV-2 Omicron variant
The Omicron variant (for other names, see § Nomenclature) is a variant of SARS-CoV-2, the virus that causes COVID-19. It was first reported to the World Health Organization (WHO) from South Africa on 24 November 2021.[1] On 26 November 2021, the WHO designated it as a variant of concern and named it after omicron, the fifteenth letter in the Greek alphabet.[2][3]

The variant has an unusually large number of mutations, several of which are novel,[4][5] (see § Mutations) and a significant number of which affect the spike protein targeted by most COVID-19 vaccines at the time of discovering the Omicron variant. This level of variation has led to concerns regarding its transmissibility, immune system evasion, and vaccine resistance. As a result, the variant was quickly designated as being "of concern", and travel restrictions were introduced by several countries in an attempt to slow its international spread. However, the variant has spread to over 50 countries by 7 December 2021.
