    The Omicron variant is a variant of SARS-CoV-2, the virus that causes COVID-19. The variant was first reported to the World Health Organization from South Africa on 24 November 2021. In the first few days of its circulation, Omicron may be spreading faster than Delta, an analysis of the global transmission of the two variants showed. Union Civil Aviation Minister Jyotiraditya Scindia informed Parliament on Thursday that 11 countries including the UK, South Africa, Brazil, Botswana, China, Zimbabwe, Mauritius, New Zealand, Hong Kong, Singapore and Israel have been placed in the 'at-risk' category amid the spread of the Omicron variant of Covid-19. The variant has an unusually large number of mutations, several of which are novel, and several of which affect the spike protein targeted by most vaccines at the time of discovering Omicron. This level of variation has led to concerns regarding 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 on African nations in an attempt to slow its international spread.
