Experts warn that the ‘horrific new Covid variant’ is the most advanced and may be even more dangerous than Delta.
After rapid spread, Delta caused many countries to reintroduce restriction and caused the UK to postpone Freedom Day this summer.

Although case numbers for B.1.1.529 may be small, virologists discovered 32 mutations in the strain, which is being called Botswana Vairant.
Many of these could increase the likelihood that the variant will escape vaccines faster and spread quicker. This is why it is still a concern, despite its low incidence.
Francois Balloux is Professor of Computational Systems Biology, Director, UCL Genetics Institute. He stated: “I would certainly expect it to not be recognised by neutralising antibodies relative Alpha or Delta.”
“It’s difficult to predict how transmissible it might be at this stage.
“For the time being, it should be closely monitored and analysed, but there is no reason to get overly concerned, unless it starts going up in frequency in the near future.”
It is believed to be an offshoot from an older variant, B.1.1. It has been discovered in South Africa and Botswana, as well as Hong Kong.
Alpha, which put the UK in lockdown right before Christmas last year, had a lineage that included B.1.17.
Although only 10 cases of this new variant have been discovered, experts suggest that there could be many more.
Experts warn that it may be more effective at spreading vaccines than it is at escaping them.
It was contracted by a South African national who traveled to Hong Kong. There were fears that it could have been spread elsewhere.
Dr Tom Peacock of Imperial College was a virologist who tweeted about the discovery. He said it was the first instance he had seen two specific mutations in one variant.
Expert described the mutation profile for the coronavirus as “really awful”.
He stated, “Export to Asia may indicate that this might be more prevalent than sequences alone would suggest.”
“Also, the very long branches and high number of spike mutations indicate this could be of concern (predicted escape of most monoclonal antibodies).
“Worth emphasising this is at super low numbers right now in a region of Africa that is fairly well sampled, however it very very much should be monitored due to that horrific spike profile (would take a guess that this would be worse antigenically than nearly anything else about).”
Professor Lawrence Young is a Warwick Medical School Virolologist. MailOnlineIt “looks like”This variant could be more efficient at avoiding vaccine immunity.
He said, however, that it was difficult to know just by looking at the pictures. [mutations]This is dependent on how the immune response to the change perceives it.
“But it seems like it’s just because of the severe loads of [mutations] — some of which we know about quite a bit in terms of harming transmission — it looks like it might be slightly more worrying than the South African variant.”
The mutations K417N, E484A in the new variant are similar to those found in strains that could avoid vaccines.
It also includes the N440K on Delta and the S477N on the New York variant. These are linked to antibody escape.
It also contains the mutation N501Y, which makes viruses more transmissible. This mutation was previously observed on the fast-spreading Alpha version.
There are many variants of the same thing, but they don’t tend to spread across a lot of cases.
They can quickly become extinct if they are found in a country with a stronger variant.
Dr Meera Chand (Covid-19 Incident Director at UKHSA) said that the UK Health Security Agency is continuously monitoring the status and development of SARS-CoV-2 variants worldwide in partnership with international scientific bodies.
“Viral mutations are a natural part of the virus’s nature, so it is not uncommon for cases with new mutations to be discovered.
“Any variants showing evidence of spread are rapidly assessed.”
A spokesperson from UKSHA said that they are investigating and monitoring this variant.
Scientists claim that the super dominant Delta could undergo self-extinction. It was already reported in one area of the world.
Japan is seeing 140 cases per day despite only being infected by the Delta strain three months ago.
Japan endured its largest Covid wave in the late summer, with cases peaking at around 23,000 a day in August.
However, the wave quickly stalled and Tokyo has only 16 new cases.
Japan’s genetic experts believe that Delta is responsible for the sudden decline in coronavirus.
Delta was already far more transmissible than the original “Wuhan”The virus is now in China.
And other variations of Delta have been shown to cause fewer symptoms, carry immune-escaping mutations, or be even more fast-spreading.
