What is the Omicron variant? SARS-CoV-2

What is Omicron?

The Omicron variant of SARS-CoV-2, the virus that causes COVID-19, is a variant of SARS-CoV-2. It was initially reported to the World Health Organization on 24 November 2021 by South Africa. The WHO identified it as a variation of concern on 26 November 2021, renaming it "Omicron," the fifteenth letter in the Greek alphabet.

WHO has designated the Omicron variation of COVID-19 as a variant of concern due to evidence that it contains numerous mutations that may affect how it acts. There is still considerable mystery around Omicron, and extensive study is being conducted to determine its transmissibility, severity, and risk of reinfection.
