The World Health Organization on Friday assigned the Greek letter Omicron to a newly identified variant of Covid in South Africa.

The United Nations Health Organization initially System B.1.1.529As a variant of concern..

Health experts I’m deeply concerned Regarding the transmissibility of the Omicron mutant, given that it has a different profile from the aberrant mutant group and other variant of concern.

“Omicron, B.1.1.529, has been named as a variant of concern because it has some properties of concern,” said Maria Van Kerkhove, WHO technical lead for Covid-19, on Twitter. Said in the video that was done. “There are numerous mutations in this variant, and some of these mutations have some worrisome features.”

Experts mean that the surge in Covid cases in Gauteng, South Africa (a highly mutated strain of the virus was first identified) is more likely to escape previous immunity than other variants. I’m afraid that it might be. According to the WHO report, the number of cases of Omicron “seems to be increasing” in almost every state in South Africa.

Organizations label Covid strains as a variant of concern only if they are more contagious, more toxic, and more proficient in avoiding public health measures, including vaccines and treatments. ..Presented data At the briefing on Thursday Sponsored by the South African Ministry of Health has shown that some of the mutations in Omicron are associated with improved antibody resistance, which may reduce the protection provided by the vaccine.

Certain mutations may be more contagious to Omicron, according to a briefing announcement, but no other mutations have been reported so far, and researchers have found that they affect the behavior of the strain. I don’t understand.

“Preliminary evidence suggests an increased risk of reinfection with this mutant compared to other VOCs,” WHO said in a statement released Friday.

Designation of new variants of concern, coupled with increased alerts from health authorities Sent a tailwind on the global market on Friday.. Oil prices and travel and leisure stocks suffered significant losses in the news.

WHO states that it will take weeks to understand how this variant affects diagnosis, treatment and vaccines.

Sharon Peacock, a professor of public health and microbiology at the University of Cambridge, said:

“It’s better to” go hard, go fast, go fast “and apologize if you make a mistake, rather than taking the academic view that you need to reach a turning point in evidence before you can take action. I believe. Rapid spread in South Africa may be due to superspreading events and other factors, but there are enough danger signs to anticipate the worst and take a preventative approach rather than expecting the best. There is, “says Peacock.

European Union, UK, Israel, Singapore, USA are in the country Imposing Travel bans for Southern African countries.

WHO warned countries of urgent travel bans and said they should take a “risk-based scientific approach” instead.

South Africa’s Foreign Ministry said the UK’s decision to take precautions on Friday morning “seems to be in a hurry because even WHO has not yet advised on the next steps.”
