According to the CDC, the genome sequencing was performed at the University of California, San Francisco and confirmed by the CDC as an omicron mutant.
California Governor Gavin Newsom warned residents not to panic. “But we should be vigilant,” he said on Twitter. “It means getting vaccinated. It will be boosted. Wear a mask indoors.” Newsam plans a press conference on the variant at 3:00 pm ET.

Omicron says “Variant of concern“According to the World Health Organization on Friday, it means that it is more contagious, toxic, or more skilled by avoiding public health measures, vaccines, and treatments. This variant has the virus in its body. It contains more than 30 mutations to the spike protein that allow it to invade. In total, the new strain contains only 10 to the receptor-binding domain, which is the first part of the virus that comes into contact with cells. It has about 50 variants.
Authorities warn that many of these mutations can lead to increased antibody resistance and infectivity, which can limit the efficacy of the Covid vaccine.
Dr. Angelique Coetzee, Chairman of the South African Medical Association, described the symptoms associated with Omicron as follows: “Very calm” So far. However, Bansel has reported symptoms in South Africa that less than 5% of the population is over 60 years old and people are old and ill.
“I think it’s really impossible to know today … I don’t think what will happen in South Africa in the next week or two is predicted to be the complete pathogenicity of the virus,” Bansel said. Stated.
Pharmaceutical companies Quick response to new variants.. Pfizer When BioNTech They are investigating Omicron and said the vaccine could be applied if needed. Johnson & Johnson He said he was already testing the vaccine against that variant. Modana He said he would test three booster candidates against Omicron, including higher doses of the original Covid booster.
