Because Omicron is the strongest mutated strain of the new coronavirus so far, it has put the world on first-level alert.

After Omicron was discovered, the World Health Organization has defined Omicron as a high-risk and highly transmissible virus. Because of this, most countries around the world attach great importance to the prevention and control of Omicron, and are also actively resisting the spread of Omicron. Despite this, Omicron cases have been confirmed in most countries in Europe, and sporadic cases have also appeared in Asia and Africa.

1. The appearance of Omicron was very sudden.

As winter is about to enter, many people think that the new coronavirus is far away from us. No one thought that the new coronavirus would come back in the form of Omicron. Omicron is a mutated strain of the new coronavirus that has 32 spike protein mutations. Under such circumstances, Omicron may be more contagious.

2. Omicron has affected all parts of the world.

After Omicron was discovered, most countries around the world immediately proposed restrictive measures on Omicron. Although most countries in Europe have restricted the entry of African residents, Omicron cases have been confirmed in many European countries. At the same time, there were at least three confirmed cases of Omicron in Hong Kong, 7 cases in South Korea, and 5 cases in Japan.

3. Omicron may affect the economy of many regions.

The main reason why I say this is because Omicron will make it more difficult to prevent and control the epidemic in various regions. In order to prevent and control Omicron, we have to sacrifice economic development. It is precisely for this reason that Omicron will further profoundly affect the economic development of various countries and regions around the world. The COVID-19 epidemic has lasted for more than two years. After the emergence of Omicron, the COVID-19 epidemic will continue to affect people's lives in new forms.
