SAN FRANCISCO It was merely a matter of time, and now it has been confirmed.

The first known case of the omicronvariant has been detected in the U.S. just days after its rapidspread in South Africaprompted worldwide concern, U.S. officials said Wednesday.

The California and San Francisco Departments of Public Healthconfirmed that a recent case of COVID-19 found on an individual in the city was caused by omicron. The person was a traveler who returned from South Africa on Nov.22 and was fully vaccinated. Genome sequencing conducted at the University of California-San Francisco confirmed the variant.

We knew that it was just a matter of time before the first case of omicron would be detected in the United States, presidential adviser Anthony Fauci said at a White House news briefing.

Dr. Grant Colfax, director of San Francisco's Department of Public Health, said at a news conference that the infected person had mild symptoms and has recovered. The individual hadthe full Moderna vaccine regimen but not the booster shot, he said.Close contacts have been notified and tested negative so far.

Much like President Joe Biden earlier this week, Colfax said the presence of omicron is a source of concern but not a reason to panic, even though he believes omicron is most likely more infectious than the delta variant.

The severity of illness omicron causes and its ability to elude vaccine-induced protection remain unknown, but Colfax said the experts he has consulted believe vaccination remains a critical element of the fight against the variant.

"So our message is the same as it was yesterday,'' he said. "To best protect against this variant, get vaccinatedfor goodness sakes if you have not been vaccinated. Get your booster if you're eligible. Continue to wear those masks inside whererequired.''

Fauci also reiterated the Biden administration's strong encouragement for unvaccinated Americans to get the shots, and for the vaccinated to receive boosters, calling both, "the solution to this problem.''

About 37% of the eligible U.S. population, including 29% of adults, are not fully vaccinated.

COVID-19 omicron variant is spreading quickly. Heres what we know.

South African scientists identified a new COVID-19 variant which has now been reported in Belgium, Botswana, Hong Kong and Israel.

Asked if Americans should change their holiday plans, Fauci said those who are inoculated should feel safe not wearing a mask if gathering indoors with others who are vaccinated. But when in a public setting where the vaccination status of others is not known, Fauci said it is very prudent to wear a mask.Thats what I do, he said.

The Centers for Disease Control and Prevention, which recently increased surveillance at four international airports JFK in New York andNewark in New Jersey, as well as those in San Francisco and Atlanta said it has been preparing for the arrival of omicron and pointed out the delta variant remains the dominant strain in the country.

"We will continue to work diligently with other U.S. and global public health and industry partners to learn more (about omicron),'' a CDC statement said.

California Gov. Gavin Newsom said in a tweet that it should be assumed the variant has found its way elsewhere in the U.S. as well.

"Theres no reason to panic but we should remain vigilant,'' Newsom said. "That means get vaccinated. Get boosted. Wear a mask indoors.''

Experts had been warning thatthe variant was likely already in the U.S. in the days before the announcement.

Fauci applauded the Biden administration's move to restrict travel from eight African countries, including South Africa, in an effort to slow the variant's spread to the United States. The CDC and the U.S. Department of State raised their alert levels for the region, each recommending against travel.

Even with the fast reaction to news of omicron, cases have also been reported in travelers in Belgium, Israel, Hong Kong and the UK. Germany, the Netherlands and the Czech Republic also have suspected cases, among at least 20 countries to report them.

Facebook removed 524 accounts and another 86 Instagram accounts linked to a Chinese network that promoted false COVID-19 claims purportedly made by a fictitious Swiss biologist, Reuters reported.

Ahead of President Joe Biden's announcement Thursday about his administration's "winter plan'' to confront COVID-19, health experts say they'd like to see more vaccines and booster shots administered, enhanced testing and genomic sequencing and increased access to therapeutics.

With November numbers in, several states have already reported COVID death totals for the yearmultiple times higher than in 2020. They include Oklahoma (nearly four times higher), Alaska and Kentucky (three times), and Maine, West Virginia and Hawaii 2 1/2 times).

Pfizer has submitted a request to the FDAto expand the emergency use authorization of its adult COVID-19 booster dose to include 16- and 17-year-olds.

People with breakthroughcoronavirus infections remain contagious for a shorter time than the unvaccinated and are therefore less likely to transmit the virus, according to a study published Wednesday in the New England Journal of Medicine.

The study, which involved 173 NBA players, their families and staff, found that vaccinated people who got COVID-19cleared the virus from their systems on average in 5 days, compared to 7 days for the unvaccinated.

Researchers also found the different strains produce roughly the same amount of the virus, but some appear to be more effective at infecting the cells than others.

CEOs at two pharmaceutical giants whose double-shot COVID-19 vaccines are dominating the U.S. market are pitching different perspectives on the impact of the omicron variant.

Moderna CEO Stphane Bancel said current vaccines for COVID-19 will likely be less effective against the newomicron variant. Bancel told the Financial Times in an interview published Tuesday that he has spoken to scientists who told him that omicron is "not going to be good." He said it could be months before enough vaccines can be produced to crushomicron.

BioNTech CEO Ugur Sahin, however, told the WallStreet Journal the Pfizer/BioNTech vaccine is effective against severe illness from COVID-19 and would likely continue to be effective against the omicron variant.

Our message is: Dont freak out, the plan remains the same. Speed up the administration of a third booster shot, Sahin said.

Until Wednesday, no omicron cases hadbeen detected yet in the U.S., where virtually 100% of infections are produced by the delta variant. New cases increased slightly in November,with a total of 2.55 millioncompared to 2.5 million in October, according to Johns Hopkins University data. However, the COVID-19 death tollwas down by nearly 15,000, from47,626 to32,951.

Televangelist Marcus Lamb, a vocal opponent of coronavirus vaccines who founded the conservative ChristianDaystar Television Network, has died of COVID-19, his family said. He was 64.

The networkannounced his death Tuesday on Twitter, saying Lamb "went home to be with the Lord this morning." His wife,Joni,confirmed on the network his coronavirus diagnosisandthat he had "pre-existing conditions" including diabetes. She said last week her husband was trying alternative treatments without success

One of the two largest Christian television networks in the world, Daystarbroadcast segments and published information online that featuredmisinformation about the virus, vaccines and unproven treatments for COVID-19.

In November, Lamb's son Jonathan said on the network that his father's illness was "a spiritual attack from the enemy"because of his advocacy against vaccines and support for alternate treatments.

The Centers for Disease Control and Prevention is directingairlines to hand over contact information for passengers coming from eight countries in Africa as part of the effort to combatthe newomicron coronavirus variant.The CDC'sContact information Collection Orderwent into effect Tuesday and affectspassengerswho have been in the Republic of Botswana, the Kingdom of Eswatini, the Kingdom of Lesotho, the Republic of Malawi, the Republic of Mozambique, the Republic of Namibia, the Republic of South Africa or the Republic of Zimbabwe within 14 days of departing for the U.S.

"CDC is issuing this directive to prevent the importation and spread of a communicable disease of public health importance," the CDC said in a statement to USA TODAY.

Authorities reported that new COVID-19 cases in South Africa nearly doubled in a day, from 4,373 Tuesday to 8,561 Wednesday, signaling a dramatic surge in the country where scientists first detected the omicron variant last week.

Saying it was necessary to keep future generations safe, the World Health Assembly on Wednesday pledged to begin work on a pandemic treaty, an international agreement to prevent and deal with future pandemics.The Assembly is the World Health Organizations governing body. Wednesdays meeting was only the second special session in its 73-year history.

The significance of this decision cannot be overstated, said Tedros Adhanom Ghebreyesus, director of the WHO,at the meeting in Geneva. The agreement will provide a platform for strengthening global health security, he said. The agreement is to be presented in 2024.

That may seem like a long process, and it is, but we should not be naive in thinking that reaching a global accord on pandemics will be easy, Tedros said.

To combat the spread of the newomicron variant, the CDC istightening testing requirements for international travelers.Currently, air travelers to the United States who haven't recently recovered from the virus including U.S. citizens must have a negative viral testbefore boarding their flight. Fully vaccinated travelers are required to take testsno more than three days before departure.But the CDC says it is "working to modify" the global testing order to give all international air travelers just one day to take a pre-departure test.

"This strengthens already robust protocols in place for international travel,"the CDC said in a statement. The U.S. is also working to stem the spread of the virus with new travel bans oneight countriesthat went into effect Monday.

As the new omicron variant spreads across the world, advocates ofmore widespread vaccinations are having an "I told you so" moment.For a year since COVID-19 vaccines first became available, a small but vocal group haswarned about the need to protect the most vulnerablearound the world.People in richer countries will not be safe, even if fully vaccinated, until those in poorer nations which make up more than half the world's 8 billion population also have the benefit of vaccines, they've argued.

The emergence of the omicron variant has fulfilled, in a precise way, the predictions of the scientists who warned that the elevated transmission of the virus in areas with limited access to vaccine would speed its evolution," Dr. Richard Hatchett, told aspecial session of the World Health Assembly this week.

The omicron coronavirus variant could have a moderate impact on the U.S. economy next year as it hurts consumer spending and worsens labor shortages and supply chain bottlenecks, intensifying already-high inflation, top economists say.

Its too early to pinpoint how omicron will affect economic growth because scientists are just starting to assess the toll it could take on global health. But under onelikely middle-ground scenario laid out by some top economists, the strain could be more infectious but not significantly more virulent than the delta variant. And it could lead to fewer government-imposed restrictions on businesses.

If thats the case, omicronor another similar variantwould cut economic growth next year by half a percentage point to 4.3% and lead to the creation of several hundred thousand fewer jobs, estimatesMark Zandi, chief economist of Moodys Analytics.
