How big a threat is Omicron?

against Omicron and may therefore need to be redesigned.At the moment, these are only fears based on hints drawn from early data on Omicron emerging from South Africa. Whether these fears will come to pass is far from certain. It will take weeks or even months before there is solid evidence from laboratory and other studies on how much of a threat Omicron really poses. In the meantime many countries are trying to stop the new variant from arriving on their shores inside travellers—and rightly so. They are buying time to prepare for the worst while hoping for the best.

The first signs that a new variant may be spreading emerged in South Africa earlier this week, when covid infections increased suddenly and sharply, from fewer than 300 cases on November 16th to more than 1,200 on November 25th. The vast majority of these infections were in one province, Gauteng, which has Johannesburg as its capital.

At first it seemed as if the infections were linked to one big superspreading event, such as a student party. That would be the sort of outbreak in which a new variant erupts briefly and then dies away. But new cases in Gauteng instead became more dispersed over time. That prompted South African scientists to look at the genomic sequence of viral samples, which is how they spotted the new variant.

Further analysis confirmed that the new variant was spreading fast in many other provinces in South Africa, even though the numbers were still small. This pattern suggests that Omicron may be outcompeting Delta. The nature of Omicron’s mutations adds backing for this hypothesis. It has about 50 of them, an exceptionally large number. Most worrying are ten found in the receptor-binding domain (RBD) of the virus’s spike protein. The RBD is the part of the virus that attaches to human cells, enabling the virus to enter and infect them. By comparison, the Beta variant has three changes to the RBD and Delta only two.

With mutations, quantity is not necessarily quality. But several of those in Omicron have been found in studies of other variants to make the virus more infectious. Some of them make it easier for SARS-CoV-2 to evade the body’s innate immune response (the immune system’s first reaction), others weaken its antibody response (a defence mechanism built as a result of prior infection or vaccination). Various combinations of Omicron’s mutations are present in all of the variants of concern to have emerged so far.

If the mutations in Omicron turn out to make covid vaccines less potent, the jabs may have to be tweaked. On November 26th Pfizer and BioNTech, makers of the covid jab that is most widely used in Western countries, said that they would be able to rework their mRNA vaccine within six weeks and ship the first batches within 100 days. The mutations in Omicron do not appear to be a threat to the efficacy of antiviral medicines for covid, but they could defeat some antibody therapies, which are given to people unable to mount an immune response.

Even if Omicron comes to dominate in South Africa, it is unclear that it will displace Delta in other parts of the world. South Africa had a wave of the Beta variant that did not become established elsewhere. Likewise, Alpha, which swept across Europe, never became established in South Africa. These patterns may have to do with variations in demography and with common infections that interact with SARS-CoV-2 in poorly understood ways.

Spain's 'Las Luminarias' festival has returned for the first time since the pandemic began, according to Reuters. About 100 horses leaped through bonfires, following a yearly ancient tradition.

Ohhh……I’m so scared again…… Utter rubbish and British racist propaganda Plandemic Scamdemic Eugenics No fear today.

World scrambles to contain omicron as scientists call for greater vaccination effortsCountries scramble to contain the new Covid-19 omicron variant as 2 cases have been identified in the UK and scientists repeat calls for greater worldwide vaccination efforts. To late it's over I saw several people testifying of how they made financial profits with the help of Kimberly Alexander from crypto trading, and I decided to give it a try and now I'm happy for getting my payout earning $15k profits from crypto trading.

World scrambles to contain omicron as scientists call for greater vaccination effortsAs countries around the globe scrambled to contain a new Covid-19 variant called omicron, scientists have said they are unsurprised at its emergence and repeated calls for greater worldwide vaccination efforts. 'Yeah, it's all those 'antivaxxers' that made it stronger. They had a strong immunity to the original, and ruined it for us 'vaxxerz', allowing it to gain power.' -Some idiot Yahoo commentator with a degree in BS.

What to know about new COVID-19 variant omicronPres. Biden: 'The news about this new variant should make clearer than ever why this pandemic will not end until we have global vaccinations.' wow Two African 'lands' are taking the lead in the struggle against neocolonialism. Ethiopia the land of origins from the East and BurkinaFaso the Land of the Upright from the West are saying NoMore. We need to hear from the North and from the South! Arise, African! Break loose!

More Countries Scramble To Curb OmicronThe new COVID-19 variant was identified in South Africa two weeks ago. Why did it take 2 weeks to reach the international press? Shouldn't the WHO be responsible for reporting 'all' new outbreaks, no matter how small, so the World has situational awareness? Fight the machine. Unvaxxed = sexy. The new variant is called Parliament = Talk Lies

OMG, is it the year 2020!? Why would we ban Africans!? AmericaFirst It’s already too late. Just give it a few weeks.

Nations close borders to prevent Omicron from spreadingConfirmed or suspected cases of the new Covid variant have already emerged in several European countries, as well as Israel and Hong Kong, just days after it was identified by researchers in South Africa.
