A new strain of the coronavirus that causes the deadly Covid-19 illness is causing havoc around the world, alarming health officials. Some have already labeled omicron as the “most alarming” variation since the delta variant, which fueled waves of infection throughout the globe a few months ago. Because of its higher transmissibility, the B.1.1.529 mutation is deemed harmful. Countries rushed to put an end to air travel, markets plummeted, and scientists convened emergency meetings to assess the consequences, which were still largely unknown.
Omicron has already been classified as a variation of concern by the World Health Organization (WHO). According to the World Health Organization, omicron poses a bigger risk than delta.
What is it called?
The variety was formerly known as B.1.1.529, but the World Health Organization identified it as a variant of concern (VOC) on Friday due to “concerning” changes and “preliminary evidence suggesting an increased risk of reinfection with this variant.” The WHO approach allocates a Greek letter to such variants in order to provide a non-stigmatizing label that does not link such variants to the location where they were initially discovered. Omicron is the name of the new variation.
When was the Omicron variant first detected?
The B.1.1.529 strain was discovered on Tuesday and labeled as a potential threat because of its large number of changes, which could allow it to bypass immunity. It was also related to a recent increase in case of numbers in the Gauteng province of South Africa, which includes Pretoria and Johannesburg. These two elements rapidly drew the attention of international watchdogs, with the UK Health and Security Agency’s top medical adviser calling the variety as the “most concerning we’ve encountered.”
Where did it come from?
Although the variation was first connected to Gauteng, it did not necessarily originate there. On November 11th, the first sample with the variation was collected in Botswana. The odd constellation of mutations suggests it may have evolved during a protracted infection in an immunocompromised person, such as an untreated HIV/Aids patient, according to scientists.
Why are scientists worried about it?
More than 30 changes have been found in the variant’s spike protein, which is the virus’s key to unlocking human cells. This is more than double the number found in Delta. Concerns have been expressed that the antibodies from past diseases or vaccinations may no longer be properly matched as a result of such a drastic change. Scientists predict that the virus will be more likely to infect – or reinfect – persons who have immunity to earlier strains based only on the list of alterations.
Is it more transmissible?
Although the situation is not yet apparent, the growth picture is concerning. In South Africa, the number of cases has risen from 273 on November 16 to more than 1,200 at the start of this week. More than 80% of them were from Gauteng, and preliminary analysis indicates that the variation has quickly become the dominant strain. The R-value, which measures how quickly an epidemic spreads, is projected to be 1.47 in South Africa overall, but 1.93 in Gauteng. There’s a chance this is just a statistical fluke tied to a super-spreader event, but the data is alarming enough to warrant precautions.
Will existing vaccines work against it?
A large number of mutations, as well as the fact that some of them have previously been linked to the potential to bypass existing immune protection, have scientists concerned. However, these are just theories, and experiments are being carried out right now to see how successful antibodies are at neutralizing the new variety. Real-world data on reinfection rates will also provide a clearer picture of the magnitude of any immunity shift.
Scientists do not expect the variation to be completely undetectable by existing antibodies; instead, they expect current immunizations to provide less protection. As a result, increasing vaccination rates, including third doses for at-risk individuals, remains a critical goal.
What about existing drugs?
Antiviral medications recently approved by the FDA, such as Merck’s pill, are expected to be as effective against the new variety because they do not target the spike protein and instead function by preventing the virus from replicating. However, monoclonal antibodies, such as Regeneron’s therapy, have a higher probability of failing or partially failing because they target sections of the virus that have mutated.
Will the variant cause more severe Covid?
There is yet no evidence on whether the variation causes a change in Covid symptoms or severity; however, South African experts will be keeping a careful eye on this. It will be several weeks before any reliable data is available due to the time lag between infections and more acute sickness. At this point, scientists say there’s no compelling reason to believe the next variation will be worse or milder.
Can the vaccines be tweaked and how long could that take?
Yes, vaccine developers are already working on modifying vaccines to include the novel spike protein in the event that a new version is required.
When the Beta and Delta variants were discovered, a lot of the preliminary work for an update was done — however previous vaccines in those situations have held up well. This suggests that research teams were already planning to develop new vaccines and had talked to regulators about what extra trials would be needed. However, it could take four to six months for new immunizations to become widely available if they are needed.
Can the vaccines be tweaked and how long could that take?
So far, the bulk of confirmed cases have been in South Africa, with a few in Botswana and Hong Kong has thrown in for good measure. A third case was discovered in Israel on Thursday evening, involving a person who had returned from Malawi, and two more cases are suspected in the country. Belgium stated on Friday that it had discovered a case in someone who had traveled to Egypt and Turkey.
However, because community transmission exists in southern Africa if there is a transmissibility advantage, the novel variety is likely to have moved undetected to other nations.
