November 29 Omicron Covid-19 variant news

Based on early evidence seen in South Africa, the Omicron Covid-19 variant is transmitting faster than the Delta variant, says Salim Abdool Karim, an epidemiologist and former head of South Africa's Ministerial Advisory Committee on Covid-19.

Karim told CNN’s John Berman on New Day Monday that there’s still a lot to learn about the traits of the variant, and it will be a couple weeks until more answers are clear.

“The reality is we’ve only know about this virus for just over a week, so we don’t really have the kind of data required to answer those questions definitively,” Karim said, when asked if the Omicron variant was more transmissible, more virulent and if it evades vaccines.

While little is known about the new variant and studies are underway, he said there are a few things that we can extrapolate and expect.

"Put very simply ... Omicron, has mutations that are common to the other four previous variants of concern. So it has mutations that are similar to the Delta variant. So we are expecting it to transmit faster," he told CNN. 

"And based on what we have seen with the overlap of the Beta variant, we are seeing some evidence of immune escape from antibodies. There will probably be some partial escape. And that's what we are expecting," Karim added.

Symptoms of this variant in patients are also harder to pin-point, he said.

Watch:

New US travel restrictions on southern Africa have come into effect, as the Biden administration seeks to respond to concerns over the Omicron variant.

The Biden administration is restricting travel from South Africa, Botswana, Zimbabwe, Namibia, Lesotho, Eswatini, Mozambique and Malawi.

Biden signed the official proclamation Friday restricting the travel of those "physically present" in the countries during the "14-day period preceding their entry, or attempted entry into the United States," starting at one minute past midnight on Monday morning.

The proclamation includes a list of those exempted from the new restrictions, including US citizens, lawful permanent residents and non-citizens who are the spouses of citizens or permanent residents.

The director of the National Institutes of Health stressed Sunday that the newly emerged Covid-19 variant "ought to redouble" vaccination efforts and other mitigation strategies, saying that while much is unknown about the variant, action should be taken now to avoid "a situation that makes this worse."

"It's certainly not good news. We don't know yet how much of an impact this will have. It ought to redouble our efforts to use the tools that we have, which are vaccinations and boosters, and to be sure we're getting those to the rest of the world, too, which the US is doing more than any other country," NIH Director Dr. Francis Collins told CNN's Dana Bash on "State of the Union."

A number of European countries have reported their first cases of the Omicron Covid-19 variant, as governments in the region race to understand the scale of its spread.

The UK has identified nine cases so far, with six of those reported in Scotland on Monday.

The Netherlands and Portugal have each discovered 13 infections -- with all of Portugal's cases being found among one Lisbon-based football team. The 13 Dutch cases were found after passengers arriving from South Africa were tested at Amsterdam's Schiphol airport on Friday.

Germany has found three cases, while Italy, the Czech Republic and Belgium each have at least one. On Monday, Austria joined the list of nations declaring its first identified case.

The true number of Omicron cases across the continent is likely to be far higher, with sequencing being undertaken to identify which new infections have been caused by the new strain.

Australia will temporarily pause the next phase of its border reopening plan to gather more information on the Omicron Covid-19 variant, its government announced Monday. 

Based on advice from the country’s National Security Committee and Chief Medical Officer Paul Kelly, international skilled visa holders, student cohorts and humanitarians, holiday makers and those holding provisional family visas will not be allowed into Australia until December 15. 

Under the country’s roadmap to safely reopen borders, these groups were due to be permitted entry on December 1. 

The temporary pause is effective immediately and will “ensure Australia can gather the information to better understand the Omicron variant, including the efficacy of the vaccine, the range of illness ... and the level of transmission," a statement from Prime Minister Scott Morrison’s office said Monday. 

Under Australia's current border restrictions, only fully vaccinated citizens, permanent residents, and their immediate family -- as well as fully vaccinated travellers from New Zealand and Singapore -- are allowed in, with limited exemptions.

Some 13 players for one Lisbon-based soccer team have tested positive for the Omicron variant, Portugal's National Institute for Health (NIH) said Monday.

The infections, among members of the SAD Belenenses side, account for all of Portugal's Omicron cases identified so far.

Belenenses’ Primeira Liga match against Benfica on Saturday was abandoned after the club was forced to name a team of nine players -- including two goalkeepers -- due to the outbreak.

Benfica -- with two more players than their opponents -- took a 7-0 lead by half-time. Belenenses then came back onto the field for the second period with only seven players.

The game was called off two minutes later when Joao Monteiro, a goalkeeper playing in midfield, was unable to continue. The referee was then forced to abandon the match which requires a minimum of seven players.

NIH director Dr. Ricardo Jorge said that one of the Belenenses players had recently taken a trip to South Africa.

In addition, another suspect case is being tested, which comes from a flight originating in Mozambique.

The overall global risk related to the new Omicron variant "is assessed as very high," according to a World Health Organization (WHO) technical brief released Monday.

Depending on how transmissible the variant is and whether it could escape immunity, "the likelihood of potential further spread of Omicron at the global level is high," the WHO brief said.

The WHO expects data from ongoing further research to be available in the coming weeks. 

The WHO urged member states to accelerate Covid-19 vaccination efforts among eligible populations, as well as "use a risk-based approach to adjust international travel measures in a timely manner."

A 37-year-old male who traveled from Nigeria has been identified as the third case of the Omicron variant in Hong Kong, health officials reported at a news briefing Monday. 

According to government data, the man had transited through Ethiopia and arrived in Hong Kong on November 24. He had been quarantining at the Ramada Hong Kong Grand View hotel before testing positive with the variant. 

The man was asymptomatic and had received two doses of the Moderna vaccine, Sophia Chan, Hong Kong's Secretary for Food and Health, said in the briefing. 

“Our existing system is robust and also able to stop any transmission," Chan added, stating that the use of boarding requirements, quarantine and testing enabled them to prevent the new Covid-19 variant entering the community.

The new Omicron coronavirus variant was identified in Scotland on Monday, with six confirmed cases.

Prior to Sunday, the United Kingdom had reported three cases -- all in England.

The Scottish cases are in the Glasgow and Lanarkshire areas, according to a Scottish government press release.

Scottish Health Secretary Humza Yousaf said Scotland will continue to align with travel restrictions introduced by the UK government, requiring fully vaccinated arrivals to take a PCR test within two days of arrival and to quarantine until a negative result is received. 

 “However, we reserve the right to go further if necessary,” he said in the press release.

Five cases of the Omicron Covid-19 variant have been reported in Australia, after genomic testing found two overseas travelers who recently arrived in the state of New South Wales were infected with the strain. 

The infected travelers both arrived in Sydney from southern Africa on a Singapore Airlines flight Sunday, Australian health officials confirmed Monday. 

Both were fully vaccinated and are isolating in the state’s Special Health Accommodation. 

There are now five confirmed cases of the Omicron Covid-19 variant in Australia -- four in the state of New South Wales and one case in the Northern Territory.

The Northern Territory case is a man who arrived in the Howard Springs quarantine facility on a government repatriation flight from Johannesburg on November 25.
