Omicron Variant: What is the new Covid variant?What are the symptoms

What is the new Omicron variant?

NS who (WHO) named the new B.1.1529 coronavirus mutant Omicron Only a few weeks after it was first detected in southern Africa, it designated it as a variant of concern.

Scientists believe that it can take months to better understand the magnitude of the threat it poses.

It is known that the mutants derived from the B.1.1 strain have “unprecedented” and “very rare” mutations because the spike protein contains 32.

Where did Omicron appear?

This subspecies was first detected in Botswana on November 11, and as of Friday, 19 new infections of the Omicron subspecies were discovered.

Country President Mokgweetsi Masisi said Thursday that some of these first cases were diplomats who traveled to Botswana from Europe and elsewhere without detailing which country.

The first case in South Africa was discovered on 14 November and the country reported the variant to WHO on 24 November.

Professor François Barrow, director of the Institute of Genetics at the University College of London, said mutations in mutants are “accumulated at once” and “abnormal constellations.”

He suggested that the variant may have emerged “perhaps in untreated HIV / AIDS patients” from immunocompromised individuals who had long-term carrier of the virus.

How popular is Omicron in the UK?

A week after the first case of Omicron was detected in the United Kingdom, the United Kingdom discovered a total of 150 infectious diseases.

Twenty-nine cases have occurred in Scotland, and Prime Minister Nicola Sturgeon said on Saturday that the case is no longer related to a single event, but to several different sources, including: He said he was. Step concert In Glasgow.

“This supports our view that community infections of this variant are currently present in Scotland,” said Sturgeon, warning that cases are expected to increase “probably significantly” in the future.

The first known case in Wales was discovered on Friday, and Northern Ireland says it expects to discover subspecies examples within a few days.

How did Omicron reach the UK?

According to Health Minister Sajid Javid, the two first cases found in the United Kingdom, Brentwood, Essex and Nottingham, are “related” and date back to southern Africa.

Targeted sequence testing of other cases has begun in these areas, but Javid said he was concerned that air passengers from South Africa who arrived in the UK last Friday could carry the Omicron variant. He admitted that he was not inspected.

Travelers were required to leave the airport in the usual way, including public transport, and then undergo a Covid test and quarantine if the test was positive, the Minister of Health said.

This means that after a phenomenal, Britain is unaware that the number of arrivals from South Africa has been infected. 10% of people on a single flight to the Netherlands Positive test for omicron variant.

Where else have Omicron cases been detected?

New infectious diseases associated with the Omicron variant have been identified in at least 38 countries, including Belgium, Canada, Australia, the Netherlands, Denmark, Germany, Israel, Italy, the Czech Republic and Hong Kong.

How contagious and dangerous is Omicron?

The World Health Organization (WHO) urges countries not to panic on Friday and prepares for the potential for Omicron to spread around the world, and another two weeks to see how contagious and dangerous this variant is. He said it would take.

Scientists believe it may be significantly more infectious than the delta mutant, but the UN Health Agency emphasized that the data are still preliminary.

The 32 variants of the variant include E484A, K417N, and N440K. These are related to helping the virus escape detection from the antibody.

Another mutation, N501Y, appears to increase the ability of the virus to invade cells and increase infectivity.

Approximately 42 vaccinations per 100 people have been given in South Africa, and WHO said coronavirus cases surged 311% over the last seven days of November compared to the previous week.

There are more cases of reinfection in South Africa than in previous variants, health agencies said, citing microbiologists at the National Institute of Infectious Diseases in South Africa.

However, despite the emergence of new variants in dozens of countries around the world, no one has died from it yet, WHO said.

Of the 150 cases identified in the United Kingdom, none have been reported to have been hospitalized, but the UK Health and Safety Agency said the infection was recent and “there is a delay between the onset of infection and hospitalization and death. “There is a tendency.

“You don’t have to panic because the situation is different than it was a year ago,” said Soumya Swaminathan, a top WHO scientist, who, like Delta Air Lines today, could make Omicron the predominant variant in the world. I suggested that. It accounts for 99% of cases.

Is Omicron resistant to vaccines?

Peplomers that coat the Covid virus allow it to attach to and invade human cells. The vaccine trains the body to recognize and neutralize these spikes.

Thirty-two mutations in the peplomer of the Omicron variant change the shape of this defense structure, making it less recognizable to the antibody.

In that case, the antibody is less powerful at attacking the virus and can evade immune defenses and cause infection.

However, WHO emergency officer Michael Ryan said on Friday that there was no evidence to revert the existing vaccine to match the new Omicron variant, and should focus on more widespread distribution of jabs. I suggested that.

What do scientists say about Omicron?

Scientists are divided on whether to worry about the latest variants.

Dr. Tom Peacock, a virologist at Imperial College London, warned that the variant could be “really concerned” because of the 32 mutations.

He wrote on Twitter that this variant “should be very, very much monitored because of its horrifying spike profile.” This means that it is more contagious than any other variant to date.

Dr. Peacock said the variant turned out to be one of these “strange clusters” and “wants” to be fearlessly contagious.

“There’s no reason to be overly worried,” said UCL professor Barrow at this point. “It’s hard to predict how likely it is to get infected at this stage.”

Professor Andrew Polard, Oxford Vaccine Group“It’s very unlikely,” he said, to create a new wave in a British pandemic.

Professor Calm Semple sitting in Sage The Advisory Group said:

“Vaccination immunity can still protect you from serious illness,” he said.

“You can get a snuffle, a headache, or a filthy cold, but the chances of entering a hospital, entering an intensive care unit, or sadly dying are greatly reduced by the vaccine and will continue in the future. Probably. “

Dr. Meera Chand, Covid-19 Incident Director, UK Health and Security Agency, said that the status of new Covid variants around the world is constantly being monitored randomly, with a small number of cases with a “new set of mutations” being “rare.” That’s not the case. ” .. “

She explained: “Due to the nature of the virus, frequent and random mutations are not uncommon for a small number of cases characterized by a new set of mutations. All variants showing evidence of spread are quickly evaluated. increase.”

What is the UK doing to keep spreads down?

Boris Johnson announced on Saturday night that he would be ordered to wear masks at stores and public transport in the UK from November 30th in response to the Omicron variant.

The Prime Minister also said that contact with the Omicron case must be quarantined for 10 days. All international arrivals should also undergo a second day PCR test and be quarantined until a negative result is obtained.

Johnson said at a news conference that the rules would be reviewed three weeks later before Christmas.

Meanwhile, South African countries have also been added to the UK’s Red List for overseas travel.

South Africa’s health minister, Joe Fara, said the travel ban imposed on his country was “not required.”

He argued that the spread of the virus could not be prevented and suggested regular tests and wearing a mask to prevent the spread of the infection.

Which country is closing the border?

WHO has repeatedly warned against the implementation of a total travel ban, except in countries where the health system cannot tolerate a surge in infection, but Japan, Morocco and Israel have with all foreign citizens. Decided to close the border.

Many countries, including the United Kingdom, the United States, and parts of the European Union, restrict travel from countries in southern Africa.

The UK has added Botswana, Angola, Eswatini, Namibia, Lesotho, South Africa, Mozambique, Malawi, Zambia and Zimbabwe to the Red List of Travel.

Australia has announced that it will delay plans to reopen its borders for skilled migrants and students by two weeks starting December 1.

In response to various travel bans, South African President Cyril Ramaphosa urged countries to “urgently overturn” these decisions as they could disrupt the economy.

Lamaposa said the emergence of Omicron was a call for awakening for the world to recognize the effects of “vaccine inequality,” and warned that further mutations would be unavoidable until everyone was vaccinated.
