Japan is further tightening its borders in response to Omicron

Japan will ban foreign nationals with Japanese residency from re-entering the country if they are traveling from 10 southern African nations over concerns of the spread of the Omicron variant, according to the country’s Ministry of Foreign Affairs.

The measure will come into force on Thursday and follows a ban on the new entry of foreign nationals enacted earlier this week. It will prevent foreign residents from returning to Japan from South Africa, Angola, Eswatini, Zambia, Zimbabwe, Namibia, Botswana, Malawi, Mozambique, and Lesotho, the ministry said.

The ministry said from Thursday, Japanese citizens and residents traveling from Sweden, Spain, Nigeria, and Portugal must quarantine at a government designated facility for three days upon their arrival.

Pfizer vaccine booster lowers risk of Covid-19 infection by 80% or more, study finds

A vial and prepared doses of the Pfizer-BioNTech Covid-19 vaccine at the Grassy Park civic center in Cape Town, South Africa, on Nov. 30, 2021. 

A third dose of Pfizer’s Covid-19 vaccine lowers the risk of testing positive for the virus by an extra 80% or more, over and above the protection offered by the first two doses, researchers reported Tuesday.

The team followed more than 300,000 people covered by Maccabi Healthcare Services in Israel who were age 40 or older and got either two or three doses of Pfizer/BioNTech’s vaccine. They found 6.6% of people who got two doses of vaccine and 1.8% of those who got three doses tested positive between August and early October. That’s an 86% reduction in risk, they said.

Note: The study was conducted before the emergence of the Omicron variant.

CDC is working to revise testing requirements for travelers to the US

The US Centers for Disease Control and Prevention (CDC) is working to revise testing requirements for inbound international travelers because of the new Omicron coronavirus variant, the agency confirmed in a statement Tuesday.

The CDC currently requires fully vaccinated travelers to be tested three days before their flight’s departure from a foreign country.

The CDC continues to recommend, but not require, that travelers get tested three to five days upon return and those who are unvaccinated should quarantine. The CDC did not offer a timeline for when any updated protocols could go into place.  

Officials across multiple government agencies huddled Tuesday night to discuss the potential changes, CNN reported earlier.

China is dealing with a Covid-19 outbreak on its border with Russia

China’s Inner Mongolian border city of Manzhouli confirmed 72 locally transmitted Covid-19 cases on Wednesday, according to local health officials. 

The Health Commission of Inner Mongolia said 62 of the new infections were found in mandated citywide testing.

Manzhouli launched three rounds of mass testing in the past three days for its 300,000 residents, according to the municipal government. Another 19 locally transmitted cases were confirmed in Zhalainuo’er district, which is on the Russian border. 

The district now has five medium-risk areas, the Manzhouli municipal government said. The recent outbreak started on November 27 when three asymptomatic cases were identified in Manzhouli. 

The city has so far confirmed 98 locally transmitted cases while Zhalainuo’er has confirmed 32 infections, according to a CNN tally. 

Hong Kong adds more countries to highest risk category over Omicron concerns

Hong Kong is adding Japan, Portugal and Sweden to its highest-risk travel category over concerns about the spread of the Omicron variant. 

Beginning Friday, the countries will be designated into Group A, according to a government news release Wednesday.

All non-Hong Kong residents who have visited Category A countries in the past 21 days are banned from entering the city, while Hong Kong residents traveling from those countries must be fully vaccinated and undergo 21 days of quarantine. They will be tested six times during their stay — and must take an additional test 26 days after their arrival.

Hong Kong’s government, which is committed to a zero-Covid approach, said all places that have detected Omicron cases will be shifted to Group A.

South Korea reports record number of daily Covid-19 cases

A healthcare worker prepares to administer a Covid-19 test at a temporary testing site outside Seoul Station in Seoul, South Korea, on Tuesday, Nov. 30, 2021.

South Korea recorded 5,123 new Covid-19 cases on Tuesday, a record single-day figure, according to a news release from the Korea Disease Control and Prevention Agency (KDCA).

KDCA said 5,075 of the new infections were locally transmitted, with 4,110 detected in the Seoul Metropolitan Area.

The country also reported 34 additional fatalities, bringing the total death toll to 3,658, according to KDCA. Some 723 patients are in critical condition, KDCA added.

South Korea has now reported a total of 452,350 cases.

As of Wednesday, 82.9% of the population had received at least one Covid-19 vaccine dose and 79.9% had been fully vaccinated, KDCA said.

Suspected Omicron cases: South Korea is investigating at least two suspected cases of the Omicron variant, with results due on Wednesday.

Meanwhile, South Korea’s Health Ministry and KDCA will form a task force along with related ministries to respond to the Omicron variant.

Research finds natural infection protects against new variants of Covid-19 — but not completely

A new study looking closely at the same group of people over time shows that natural coronavirus infection can protect people from infection with new variants — but it doesn’t offer enough protection to prevent new waves of infection across a population.

The ongoing study of more than 2,000 volunteers in Nicaragua shows people infected in the first waves of Covid-19 were protected against severe disease when the Gamma and Delta variants swept through later. 

The researchers, led by epidemiologist Aubree Gordon and colleagues at the University of Michigan, also said they identified what are known as correlates of protection — the measurements needed to know whether someone is likely to have immunity against another infection.

The team has been regularly testing the volunteers for flu for several years and added coronavirus when the pandemic started. By March of this year, more than 62% of them had been infected at least once.

“After March 2021, Gamma and Delta variants predominated,” the team wrote.

People who had antibodies against coronavirus were 69% less likely to get infected a second time and the higher their levels of antibodies directed against the virus’ spike protein, the less likely they were to become infected again. This measurement is known as a correlate of protection.

The team did not test the effects of vaccination for this report but will be testing that in future research, Gordon told CNN.

Israeli health minister says there are "indications" Covid vaccine protects against Omicron

There are “indications” that people who received a coronavirus vaccine booster are “protected” against the Omicron variant, Israeli Health Minister Nitzan Horowitz said Tuesday.

Boosters have been available in Israel to anyone over age 16 since late August, five months after their second dose of the vaccine. A person is not considered fully vaccinated in the country until they have received a third dose, once they are eligible for it.

US considers stricter coronavirus testing for international travelers

Top US government officials are considering requiring everyone who enters the United States to be tested for Covid-19 the day before their flight and having all travelers — including US citizens and permanent residents — be tested again after returning home, regardless of vaccination status, sources familiar with the thinking have told CNN.

Officials were deliberating Tuesday night and no final decisions have been made, but an announcement could come as soon as this week. Currently, travelers are required to test three days before their departures. The move under consideration would shorten that timeline to one day.

On Monday, the US banned all travel from South Africa and seven neighboring nations, with the exception of US citizens and legal permanent residents, who must test negative to enter the US but not once they have arrived.

Biden says decisions on southern Africa travel restrictions is "going week-to-week"

President Joe Biden speaks to members of the media before boarding Air Force One at Minneapolis-Saint Paul International Airport in Minneapolis, Tuesday, November 30, after visiting Dakota County Technical College in Rosemount, Minnesota.

President Biden said on Tuesday that travel restrictions on countries in southern Africa “kind of depends” on the Omicron coronavirus variant, also suggesting he won’t “shock allies” like former President Donald Trump did when he barred travel from Europe earlier in the pandemic.  

Asked if he’s considering any new vaccine requirements or efforts to get more Americans vaccinated, Biden told reporters on a tarmac in Minnesota, “I’ll be talking about that on Thursday.” 

The President also said that it “kind of depends” how long travel restrictions on Southern Africa will remain in place.  

When asked about travel restrictions, given that former President Trump’s 2020 decision to bar travel from Europe shocked allies, Biden remarked, “Unlike Trump, I don’t shock our allies.” 

FDA advisers vote to recommend emergency use authorization of Merck's pill to treat Covid-19

This photo from Merck & Co, Inc., provided in May, shows Molnupiravir capsules.

Advisers to the US Food and Drug Administration voted 13-10 Tuesday to recommend emergency use authorization of a pill made by Merck and Ridgeback Biotherapeutics to help treat Covid-19.

Members of the FDA’s Antimicrobial Drugs Advisory Committee were split in their vote to recommend molnupiravir, which can reduce the risk someone will progress to severe disease or death by about 30%.

The pills must be taken within five days of symptoms starting to do much good, and people must take pills twice a day for five days. Members of the committee were worried about risks to pregnant women.

Molnupiravir is not the only antiviral scientists are developing against Covid-19. Pfizer applied for authorization of its antiviral pill this month. The FDA has not yet set a date for its advisory panel to review that drug.

Next, the FDA will consider the committee’s recommendation. It doesn’t have to follow the committee’s advice, but often does.

Remdesivir, sold under the brand name Veklury, is an antiviral approved to treat Covid-19 but it’s infused, not given as a pill.

Canada is now reporting 6 cases of the Omicron variant

Alberta’s top doctor confirmed Canada’s sixth case of the new coronavirus variant Omicron. 

In addition, federal health officials say they will expand the travel ban on foreign travelers from countries in Africa to include Nigeria, where most of Canada’s cases have been linked.

Some background: Earlier today, Canada confirmed five cases of the Omicron variant and health officials in several provinces say they continue to investigate dozens of other suspected cases across the country.

Four of the cases have been confirmed in Ottawa and a fifth case was been identified in the province of Quebec.

Quebec’s health minister, Christian Dubé, speaking at a news conference Monday said more than a hundred travelers from southern African countries were asked to take a new Covid-19 test and isolate. 

US stocks sink on Omicron and Fed fears

US stocks tumbled Tuesday as renewed concerns about the Omicron variant of Covid-19 weighed on sentiment.

Comments from Federal Reserve chair Jerome Powell didn’t help. Powell told Congress that the Fed no longer thought inflation was “transitory,” and he hinted that the Fed could accelerate its plans to cut back on, or taper, bond purchases. 

Here’s how stocks closed the trading day:

  • The Dow dropped more than 650 points, or 1.9%
  • The S&P 500 also fell 1.9%
  • The Nasdaq Composite ended the day down 1.6%.

Note: As stocks settle after the trading day, levels might still change slightly.

Latin America's first Omicron variant cases reported in Brazil 

The Brazilian health agency, Anvisa, said on Tuesday that two Brazilians had tested positive for the new Omicron coronavirus variant. 

This marks the first case of the Omicron coronavirus variant in Latin America and makes Brazil the 20th country to report the new variant.

A passenger, who had flown in from South Africa on the 23rd with a negative Covid-19 test result, did a new test along with his wife to prepare for a return flight back to South Africa when the results came back positive. 

Brazil has since suspended flights from South Africa.

The samples are being sent to another laboratory for confirmatory analysis, Anvisa said. 

It's too soon to know if Omicron causes less severe illness, Fauci says

It’s too soon to know if the Omicron variant of coronavirus causes less severe disease than the Delta variant – in spite of reports that many cases so far have been mild, Dr. Anthony Fauci said Tuesday.

Most cases of Covid-19 overall are mild, and especially among younger patients. But nonetheless the virus can and does cause severe disease as it spreads among populations and has killed 5.2 million people globally and more than 779,000 in the US alone, according to Johns Hopkins University.

Fauci, who is director of the National Institute of Allergy and Infectious Diseases, noted that some South African physicians have reported the patients they treated had mild disease. But they were treating young people, Fauci said.

“Dr. Walensky and I specifically asked our South African colleagues that on the most recent Zoom call that we had, and they agreed with us that it’s too early to tell. They’re hoping that it is going to, across the board, give a lower level of severity, but they don’t know that right now,” he added.

In the meantime, vaccination and boosters should protect people, Fauci said. Boosters, especially, can bring antibody levels up to where there is a cushion of extra protection that can cover even variants of the virus.

“And that’s usually most manifested in protection against severe disease that leads to hospitalization,” Fauci said.

“So when we say that although these mutations suggest a diminution of protection and a degree of immune evasion, still from the experience that we have with Delta (you) can make a reasonable conclusion that you would not eliminate all protection against this particular variant,” he said.

“And that’s the reason why we don’t know what that degree of diminution of protection is going to be. But we know that when you boost somebody, you elevate your level of protection very high. And we are hoping, and I think with good reason, to feel good that there will be some degree of protection. Therefore, as we said, if you’re unvaccinated get vaccinated, and if you’re vaccinated, get boosted,” he added.

Testing Omicron to see how dangerous it is compared to other variants will take two weeks or so, Fauci says

Tests to look for whether the Omicron variant of coronavirus is more dangerous than Delta will take two weeks or so, Dr. Anthony Fauci said Tuesday.

Fauci said researchers will test the virus in the laboratory and also look at what it does in real life to see whether the highly mutated strain is more transmissible, more likely to evade the effects of vaccine or treatments, and whether it can cause more severe disease. 

Lab tests take time, Fauci, who is director of the National Institute of Allergy and Infectious Diseases, told a White House Covd-19 briefing.

Labs are already taking blood from people who have been vaccinated, as well as from people who have recovered from infection – that’s the convalescent sera – to see what happens when it’s exposed to the new variant.

“That will give you a pretty good idea as to what the level of immune evasion is,” he said.

The blood serum contains the antibodies as well as cells called B cells and T cells that fight infections.

“That process will take likely two weeks or more, perhaps even sooner, depending upon how well the virus grows in the isolates that we get. That’s the first thing,” Fauci said.

“And in those countries in which there are a lot of cases, like South Africa, the computational biologists and the evolutionary biologists are going to be getting a good feel as to what the competition of this virus would be with Delta. Those are just a few of the things that will take a couple of weeks to a few weeks to learn,” he added.

US public health labs sequencing 4 times as many coronavirus specimens now compared to a year ago

Coronavirus sequencing efforts in the United States grew in the past year – well before the emergence of the Omicron variant – with public health labs sequencing four times as many specimens now than a year ago, according to the Association of Public Health Laboratories.

Sequencing samples of coronavirus helps scientists to identify emerging variants.

Currently, there are about 68 state and local public health laboratories sequencing for coronavirus variants as part of the US Centers for Disease Control and Prevention’s national strain surveillance network, Scott Becker, APHL’s chief executive officer, told reporters during a virtual news briefing Tuesday. 

“Nationally between 5% and 10% of all diagnostic specimens are sequenced and come from public health laboratories, commercial laboratories, CDC-contract labs, academic labs, and other partners,” Becker added.

He said they have not found the Omicron variant in the US yet, “but we fully expect that we will,” Becker said.

“Our system can detect variants down to 0.1% of circulating viruses, so we’re confident that it can be found,” he added.

CDC expanding surveillance at 4 big US airports to look for Omicron, agency's director says

Travellers walk through Terminal 4 at John F. Kennedy International Airport (JFK) in New York, U.S., on Wednesday, November 24, 2021. 

The US Centers for Disease Control and Prevention is expanding surveillance at four major international airports to keep an eye out for the Omicron variant of coronavirus in travelers, the agency’s director said Tuesday.

The airports include two in the New York City area, plus ones in Atlanta and San Francisco.

“CDC is evaluating how to make international travel as safe as possible, including critical partner testing closer to the time of flights and considerations around additional post arrival testing and self-quarantine,” CDC Director Dr. Rochelle Walensky told a White House Covid-19 briefing.

“Thanks to our updated travel policies earlier this month, we are also actively working with the airlines to collect passenger information that can be used by CDC and local public health jurisdictions to enhance contact tracing and post-arrival follow-up should a case be identified in a traveler.” 

CDC is also keeping in close touch with state and local health officials, she said.

“As we have done throughout the pandemic, we are holding regular, even daily calls, with local county and state health officials and our public health partners. These calls include state, county and city health officials, state epidemiologists, laboratory directors and partners from public health organizations. And we are conveying the knowledge we have to these partners and we are relying on their local expertise to provide information,” Walensky said.

“We have worked to address that spread of infection for travel during travel through nesting vaccination and pre departure testing for international passengers. And we are continuously working closely with our public health partners, both here in America and around the world,” she continued.

Oil tumbles below $65 for the first time in 3 months on Omicron fears

Oil prices fell sharply on Tuesday to levels unseen since late August on worries that Omicron will dent previously robust demand for energy. 

US crude dropped nearly 7% to $65.30 a barrel in afternoon trading. At session lows, oil fell below $65 a barrel for the first time in three months. 

The selloff leaves oil down by a staggering 23% in just the past three weeks. As recently as November 10, crude was flirting with $85 a barrel.

The reversal was at first driven by an expectation that the United States and other countries would tap strategic oil reserves to cool off red-hot prices. 

But more recently, oil is losing steam on fears the new coronavirus variant will hurt oil demand by causing fewer people to drive, fly and commute. Crude plunged by 13% on Friday, its worst day since April 2020, and only posted a modest rebound on Monday.

Omicron variant found in 20 countries, but not in the US yet, Fauci says

The Omicron variant of coronavirus has been found in 20 countries so far but not the US yet, Dr. Anthony Fauci, chief medical adviser to President Biden and director of the National Institutes of Allergy and Infectious Diseases, said Tuesday.

Fauci said Omicron looks very different from the now-dominant Delta variant.

“This mutational profile is very different from other variants of interest and concern. And although some mutations are also found in Delta, this is not Delta. It’s something different. And these mutations have been associated with increased transmissibility and immune evasion, whereas other of the mutations have not yet been characterized as to their functional capability,” he said.

“Obviously, when you look at the molecular configuration of those particular variants, it suggests strongly that there’s increased transmission compared with the original pandemic virus, but it is difficult to infer what the relationship between this transmissibility is and Delta. Although you can suggest it might be more, we do not know until we see the dynamics of how this evolves,” he added.

Fauci said while the variant carries many mutations, vaccines are likely to protect people against severe disease at the least, even if the variant doesn’t stimulate the immune system in the same way as older variants do.

“What about vaccine effectiveness? Now obviously, significant reductions in the neutralizing titers are possible. And we say that because the mutations suggest immune evasion. But remember, as with other variants, although partial immune escape may occur, vaccines, and particularly boosters, give a level of antibody that even with variants like Delta give you a degree of protection, particularly against severe disease. So there’s every reason to believe as we talk about boosters, when you get a level high enough that you are going to get at least some degree of cross protection, particularly against severe disease,” he said.

Fauci continued: “And what about disease severity? Again, these are estimates and with a small number of cases, it is very difficult to know whether or not this particular variant is going to result in severe disease. Although some preliminary information from South Africa suggests no unusual symptoms associated with the variant, we do not know and it is too early to tell.”
