Washington (AP) — A Californian vaccinated with COVID-19 identified the first case of an Omicron variant in the United States, the White House announced Wednesday. Scientists continue to study the risks posed by new viruses. distortion.
Dr. Anthony Fauci told reporters that the person returned from South Africa on 22 November and was a positive traveler on 29 November.
At the end of last month, the Biden administration moved to limit travel from southern Africa, where variants were first identified and spread. Case clusters have also been identified in about 20 other countries.
“We knew that it was only a matter of time before the first case of Omicron was detected in the United States,” Fauci said.
Officials contacted everyone in close contact with the person and said they were all negative.
Genome sequencing was performed at the University of California, San Francisco, and the sequence was confirmed by the US Centers for Disease Control and Prevention.
The Centers for Disease Control and Prevention has strengthened U.S. inspection rules for international travelers, including requiring all travelers to be inspected within one day of boarding a flight to the United States, regardless of vaccination status. We are taking steps to do so. We were also considering requiring a post-arrival test.
Authorities said these measures only “buy time” for the country to learn more about new varieties and take appropriate precautions, but given its transmissibility, arrival in the United States is avoided. I didn’t.
Much remains unclear about the new mutant strain, whether it is more contagious than the previous strain, whether it makes people more seriously ill, whether it can block the vaccine, and much more. Fauci, a top infectious disease expert in the United States, said that as scientists grow and test laboratory samples of the virus, more will be known about the Omicron strain in 2-4 weeks.
The first proceedings in the United States will be announced before President Joe Biden plans to outline his strategy for fighting the virus during the winter on Thursday. Biden sought to calm his vigilance against Omicron variants, saying it was a source of concern but “not a cause of panic.”
Biden and public health officials are increasingly calling for more Americans to be vaccinated and for vaccinated people to get booster shots to maximize protection against the virus. It has become.
