Health officials in the UK on Friday called the variant of the coronavirus found in India a “variant of concern” and it seems to be spreading as fast as they found it last year, causing new waves of Covid-19 and high power. into the blockade of several countries.
The new data also seen in India suggest that this may be true. According to the latest genome sequencing data shared by the Indian laboratories GISAID – B.1.617.1 and B.1.617.2 with a global repository, they accounted for 58% of all samples sent in the last 30 days.
B.1.617.2 It is one of three lineages of the B.1.617 variant that is spreading in India, and experts fear that it may be behind the steady rise in cases where the country’s health system has been crushed.
Public Health England reported on Friday that it had found that B.1.617.2 had spread to the UK similar to the first days of B.1.1.7, which is now known as the UK variant.
Cases of variant B.1.617.2 have risen from 202 to 520 in the past week, the PHE said, mainly in London and the north-western town of Bolton, with almost half of the cases related to contact with a passenger.
“I think we need to be very careful with that,” UK Prime Minister Boris Johnson told reporters, citing the variant, Reuters reported. “We’re doing a tremendous amount, of course, when we find outbreaks of the Indian variant when we do surface tests to make sure we’re doing door-to-door testing.”
He mentioned evidence that PHE spreads faster than the original version of the virus and can spread as quickly as B.1.1.7.
“There is currently insufficient evidence to show that a recently detected variant in India causes more serious diseases or that vaccines that are now widespread are less effective,” the PHE said in a statement.
According to data analysis on GISAID genome sequencing on Outbreak.info, Bihar, Chhattisgarh and Jharkhand reported high numbers of B.1.617.2 variants, and Bihar also reported several samples with B.1.617.1.
This study is probably based on data uploaded to GISAID, and may not reflect the full scale of the occurrence or how these variants relocate to others.
The original variant, B.1.617, was first observed in India, was first detected in October, but PHE and Indian experts have classified three different subtypes, all of which have slightly different mutations.
Other worrying variants include variants identified in Kent, south-east England, as well as in South Africa and Brazil.
B.1.617 was also classified as VOC and the Union health ministry said on Wednesday that the variant was found in 1,504 sequenced samples, compared to the 1,391 samples that showed the UK variant.
The new clues will have several implications in India: a more contagious variant will require stricter honesty, such as containment blockades and countries will suspend arrivals from India until the outbreak is controlled.
But to better understand how it behaved, experts have asked Indian authorities to provide details on when and where samples of the variant were found, which could help determine whether the other variants are being moved.
Experts say UK data has confirmed that B.1.617.2 may be more appropriate. “The growth rate against B.1.617.2 against B.1.1.7 seems to be similar to that which B.1.1.7 replaced the previous variant. This means that the relative adequacy of B.1.617.2 and B.1.1.7 may be similar to the relativity of the previous variants of B.1.1.7, ”Deepti Gurdasani, an epidemiologist at Queen Mary University University in London, said in a tweet.
“This is worrying because we have seen how quickly a new variant can change the shape of the pandemic and how quickly it spreads. It now seems to double B.1.617.2 a week, so it could become dominant in some parts of the UK 2-4 weeks, ”he added.
