Answer:
The Omicron variant of COVID-19 has been called a variant of concern by WHO based on the evidence that it has several mutations that may have an impact on how it behaves. There is still substantial uncertainty regarding Omicron and a lot of research underway to evaluate its transmissibility, severity and reinfection risk.

The more opportunities a virus has to spread, the more opportunities it has to undergo changes.

It is therefore essential that people get the vaccine when available to them and continue to follow existing advice on preventing the spread of the virus, including physical distancing, wearing masks, regular handwashing and keeping indoor areas well ventilated.
Explanation:
People around the world are concerned about the Omicron variant of COVID-19The 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.[1] 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[4][5] (see § Mutations) and a significant number of which affect the spike protein targeted by most COVID-19 vaccines at the time of the discovery of 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.
Compared to previous variants of concern, Omicron is believed to be far more contagious (spreading much quicker),[6] and spreads around 70 times faster than any previous variants in the bronchi (lung airways), but it is less able to penetrate deep lung tissue, and perhaps for this reason there is a considerable reduction in the risk of severe disease requiring hospitalisation.[7] However, the extremely high rate of spread, combined with its ability to evade both double vaccination and the body's immune system, means the total number of patients requiring hospital care at any given time is still of great concern.[7]
The new variant was first detected on 22 November 2021 in laboratories in Botswana and South Africa based on samples collected on 11–16 November.[8][9] The first known sample was collected in South Africa on 8 November.[10][11] In other continents, the first known cases were a person arriving in Hong Kong from South Africa via Qatar on 11 November, and another person who arrived in Belgium from Egypt via Turkey on the same date.[12][13] As of 16 December 2021, the variant has been confirmed in more than 80 countries.[14] The World Health Organization estimated that by mid-December, Omicron likely was in most countries, whether they had detected it or not
