What is Omicron variant and what are the symptoms of Omicron infection

Recently, COVID-19 has mutated again, and the new virus strain after mutation has been named Omicron by WHO. As of now, this strain has appeared in 17 countries and regions. So, what is the Omicron variant? What are the specific symptoms of Omicron infection? Why was it named Omicron? 1、 What is the Omicron variant? The Omicron virus strain is a variant of COVID-19. It is understood that this is the fifth variation of the COVID-19 since the global outbreak. The first variation was found in the UK in 2020 and was named Alpha; The second mutation occurred at the end of 2020 and was named Beta; The third mutation appeared in December 2020, detected in the Brazilian Amazon and named Gamma. Delta is a variant that appeared in India in early 2021 and has caused several rounds of local outbreaks in China. But the Omicron variant has a higher viral load and stronger infectivity than the Delta virus. Below are a few key points that everyone is concerned about:

1. Does Omicron exist in China? As of now, there are two confirmed cases of Omicron in Hong Kong, China. One of the cases is a recent entry from South Africa into Hong Kong, while the other case may have been cross infected during hotel quarantine. How strong is the transmission power of Omicron? According to epidemiological and laboratory monitoring data, there has been a significant increase in the number of cases infected with the Omicron variant, which has partially replaced the Delta variant and increased transmission by 3% compared to the Delta variant

by 7.5%.

3. Is the vaccine effective for Omicron? Virus disease experts from the Chinese Center for Disease Control and Prevention said that COVID-19 vaccine is still effective for Omikjon, which can effectively reduce the severity and death, and can reduce the scale of infection. 2、 What are the specific symptoms of Omicron infection? Every time COVID-19 mutates, the symptoms of patients after infection will also be different. According to infected individuals in South Africa, the symptoms of being infected with Omicron may be slightly different from those of the Delta variant. Specifically,

1. Symptoms of Omicron infection: Extreme fatigue. Previously, patients infected with Delta virus in China reported mild fatigue, and the prominent symptom of Omicron infection is extreme fatigue. I have no energy at all when doing things, and I feel like sleeping all the time.

2. Symptoms of Omicron infection 2: Physical pain. According to confirmed cases in South Africa, most infections have muscle soreness. But there are many reasons for muscle soreness [SEP], and if it is caused by exercise, it can be ruled out as an Omicron infection.

3. Symptoms of Omicron infection: Mild cough. If there is contact with a person infected with the Omicron virus or if there is a coincidence in the trajectory, mild cough may indicate infection with the virus and must be taken seriously. 3、 Why was it named Omicron?

1.

Reason 1: WHO names the variant strain of B.

1.

1.529 that appeared in South Africa as the highest level COVID-19 variant and named it Omicron according to the notification issued by WHO on the afternoon of 26th.

2.

Reason 2: The name of COVID-19 mutants after each mutation is very novel according to the previous name, so this Omikjon mutant also follows the previous naming experience. In general, the Omicron virus strain is a variant of COVID-19, and the symptoms of infection with Omicron virus include extreme fatigue, slight cough, body pain, etc. Naming Omicron is determined by the World Health Organization, and it's not about choosing whatever name you want.
