Authorities confirmed the first known Omicron variant (B.1.1.529) The case in the United States.
The case was an individual who returned from South Africa to California on 22 November and tested positive for COVID-19 on 29 November, said Dr. Anthony Fauci, director of the National Institute of Infectious Diseases. It states as follows. White house briefing Wednesday (December 1st). He said none of the close contact with the individual was tested positive.
The individual was completely vaccinated and had a mild experience COVID19 Symptoms It’s improving, Fauci said. As far as he knows, that person hadn’t received a booster shot.
The University of California, San Francisco confirmed that individuals were infected with the Omicron variant after university scientists analyzed individual test samples. The CDC Lab later confirmed the discovery.
“We knew that it was only a matter of time before the first case of Omicron was detected in the United States,” Forch said in a briefing.
South African scientists first reported Omicron to the World Health Organization on 24 November, and WHO identified it as a “variant of concern” on 26 November. Live science previously reported.. Since the discovery of the variant, dozens of other countries, including Canada and the United Kingdom, have identified cases of Omicron.
Scientists still do not know if the Omicron variant is more contagious or more severe than other coronavirus variants. And they still don’t know how effective current vaccines are in protecting against Omicron.Obviously, there are many in Omicron mutation The arm of the novel to the spike protein coronavirus Used to latch and invade human cells.
In the briefing, Fauci said scientists should be able to answer some of these questions in a couple of weeks.
He said people should continue masking indoors when collecting settings. Fauci also emphasized the importance of obtaining the COVID-19 vaccine if it has not yet been vaccinated. Also, if 6 months have passed since the last vaccination with the Moderna or Pfizer-BioNTech vaccine, a booster shot is required. Said. For those who have been vaccinated with Johnson & Johnson, booster immunization is recommended 2 months after the injection.
The vaccine does not target specific mutants such as Delta or Omicron, but a sufficiently high level of immune response (from boosters, etc.) provides “spillover protection,” Forch said.
“We don’t have much data, but there are many reasons to believe that such an increase in boost will help prevent serious illnesses of mutants, at least like Omicron.”
