ABSTRACT

The Omicron variant is a variant of SARS-CoV-2, the virus that causes COVID-19. As of December 2021, it is the newest variant. It was first reported to the World Health Organization (WHO) from South Africa on 24 November 2021. On 26 November 2021, the WHO designated it as a variant of concern and named it "Omicron", the fifteenth letter in the Greek alphabet. The variant has an unusually large number of mutations, several of which are novel (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, despite initial reports indicating that the variant causes less serious disease than previous strains. 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. The Omicron can be classified into the different types such as, Variant Being Monitored (VBM) Alpha (B.1.1.7 and Q lineages, Beta (B.1.351 and descendent lineages), Gamma (P.1 and descendent lineages), Epsilon (B.1.427 and B.1.429), Eta (B.1.525), Iota (B.1.526), Kappa (B.1.617.1), Mu (B.1.621, B.1.621.1), Zeta (P.2), Variant of Interest (VOI), Variant of Concern (VOC), Delta (B.1.617.2 and AY lineages), Omicron (B.1.1.529 and BA lineages), Variant of High Consequence (VOHC). In this review article include the causes, symptoms and transmissions, of the omicron variant and also include the treatments, prevention of the omicron virus.
