Fauci warns omicron variant ‘raging through the world’: COVID updates

Omicron ‘most significant threat’ since pandemic began, U.K. health authority warns

LONDON — Omicron is “the most significant threat” to public health in the U.K., authorities warned Wednesday, as the World Health Organization cautioned that the highly contagious Covid-19 variant was spreading at an unprecedented rate.

The number of Covid-19 infections over the coming days will be “quite staggering” compared to previous variants, said Jenny Harries, the head of the U.K. Health Security Agency.

Hours after her warning, government data showed that 78,610 new cases had been recorded in the U.K. as of 9 a.m. local (5 a.m. ET) on Wednesday morning — the highest daily number of laboratory confirmed cases since the pandemic began.

Despite the advisories from domestic and international experts, there has been growing resistance to the British government’s new Covid-19 measures — notably from members of Prime Minister Boris Johnson’s Conservative Party.

New regulations intended to help slow the spread of omicron, including masks in public places and the use of Covid-19 passes for some venues, passed in Parliament on Tuesday evening. However, scores of Conservative lawmakers refused to back the new measures.

Some called the new measures too severe and questioned the introduction of a certificate of vaccination or proof of a negative Covid test to enter some venues.

“We are not a ‘papers, please’ society. This is not Nazi Germany,” Conservative lawmaker Marcus Fysh told BBC radio on Monday.

The comment led to pushback both in Parliament and on social media, where the term Nazi Germany trended, and Fysh later apologized for the comparison in a piece he wrote for London’s Jewish Chronicle newspaper.

Omicron’s quick spread

Just over two weeks after the first cases were detected in the U.K., omicron is now the dominant variant in London, the city’s public health chief Kevin Fenton said in a tweet Tuesday.

Since the start of the pandemic, more than 170,000 people have died in the U.K. with Covid-19, one of the highest death tolls in Europe. However, it was the first country to roll out a clinically approved Covid vaccine, and more than 68 percent of the population has been fully vaccinated. That’s ahead of the U.S., where just over 60 percent have been fully vaccinated, according to Our World in Data.

Omicron’s quick spread in Britain, with cases doubling in less than two days in most regions, came as the head of the WHO warned that measures, including masks, social distancing and ventilation, were needed alongside vaccines.

“Omicron is spreading at a rate we have not seen with any previous variant,” Director-General Tedros Adhanom Ghebreyesus wrote Tuesday on Twitter. “I need to be very clear: Vaccines alone will not get any country out of this crisis.”

In the U.S., rising cases and the fear that omicron could spark a new wave of infections led California to reimpose its indoor mask mandate for at least a month.

Europe, meanwhile, is facing a “double challenge,” with high numbers of Covid-19 infections, hospitalizations and deaths driven by the delta variant, as well as the spread of omicron, European Commission President Ursula von der Leyen said in the European Parliament. By mid-January, omicron is expected to be the dominant variant in Europe, she said.

More than 5,300 cases of omicron have been recorded in the U.K., with 10 people hospitalized. One person died after contracting the variant.

Johnson, who warned Sunday that “there is a tidal wave of omicron coming,” ramped up the country’s booster program, saying that he wants to offer all residents 18 and older a third dose to by the end of the month.

His push for boosters led to long lines at walk-in vaccination centers, with people reporting on social media that vaccines had run out before their turn came. The health service, which provides U.K. residents with free rapid Covid-19 test kits, has faced shortages on its website since Johnson’s televised address Sunday.

The U.K. administered more than 513,000 booster vaccines on Monday, its third highest rate since October.

The push for the third doses also came as the first real-world study of the variant in South Africa showed that two doses of the Pfizer-BioNTech vaccine offered reduced protection against omicron. However, the variant also appeared to cause less severe illness in South Africa, where it was first discovered last month.

The analysis, released Tuesday by South Africa’s largest health care administrator, found that on average 29 percent fewer people were being admitted to a hospital than previously with the delta variant. However, the study also found that two Pfizer jabs gave 70 percent protection against hospitalization from the new variant, compared with 90 percent seen in the delta wave.

CDC warns about rising flu cases in children, young adults

The Centers for Disease Control and Prevention issued a health advisory Wednesday that cases of influenza have been rising among young adults in recent weeks.

While flu cases are still low nationally, more than 90 percent are among children and young adults ages 5 to 24, according to the CDC.

Most cases are of the H3N2 lineage — a strain that health experts say is particularly troublesome, as it tends to mutate faster than other variants of influenza. The last time H3N2 was the dominant strain was during the 2017-18 flu season, when the U.S. had 710,000 flu-related hospitalizations and 52,000 flu-related deaths, the most since the 2009 H1N1 flu pandemic

The CDC has been investigating a flu outbreak at the University of Michigan, where hundreds of students have tested positive. Flu outbreaks have been reported at other college campuses in the past month.

Experts are concerned that college students and other young people who may have been exposed to flu could spread it around the country as they travel home for the holidays.

“This is the time of the year when many people are going to be gathering together for the holidays for either Thanksgiving, Christmas or New Year’s, and there’s just the potential to amplify it,” said Dr. Isaac Bogoch, an infectious disease specialist at the University of Toronto.

He said people, especially those most at risk for severe disease, should get vaccinated, because the virus doesn’t stay within a particular age group for long.

“It’s coming. It’s not quite clear how large a flu season we’re going to have, but we are going to have a flu season,” he said.

The flu season typically runs from October to as late as May, with activity tending to peak from December to February, according to the CDC.

Influenza experts had previously said they were concerned that the country could be at risk for a severe flu season this year after seasonal flu cases reached an all-time low last year, when large parts of the country were shut down because of the coronavirus pandemic.

Experts urge people to get both Covid and flu vaccinations, saying an increase in flu infections this winter could put more burden on the country’s health care system, which is already dealing with a surge in coronavirus cases.

As part of the health advisory, the CDC recommended that people with flulike symptoms be tested for both influenza and Covid.
