UK variant: first images of coronavirus B.1.1.7 mutation


Researchers from the University of British Columbia (UBC) in Canada have published the first molecular images of the B.1.1.7 COVID-19 mutation which was first discovered in the UK in December last year.

Look:

The study looked at “the UK variant (B.1.1.7) of SARS-CoV-2 considered more infectious than previously circulating strains due to several changes, including the N501Y mutation. She concluded that “N501Y mutant are consistent with the expectation that the rapid spread of the UK variant of SARS-CoV-2 is probably due to the fact that the virus is more infectious. »

The study warned that “with the continued spread of SARS-CoV-2, it seems likely that other mutations that improve the viral form will emerge. The results have been published in PLOS Biology, a peer-reviewed scientific journal.

Professor in the Department of Medicine of Biochemistry and Molecular Biology at UBC, Dr. Sriram Subramaniam said existing vaccines are likely to remain effective in preventing mild and severe cases caused by B.1.1.7.

The University said the variant can still be neutralized by antibodies that stop the unmutated version of SARS-CoV-2 from entering human cells. Researchers are also studying the Variant B.1.617 (Indian)including P.1 (Brazilian), B.1.427/B.1.429 (California) and B.1.351 (South African).

The strain that first appeared in England is called 501Y.V1 or VOC202012/01 and belongs to the B.1.1.7 line. The English, the South Africans and the Brazilian variants all share a particular mutation called N501Y which is believed to be more infectious. According to British researchers, the strain that appeared in England was up to 70% more deadly.

Thailand reported on Monday the highly transmissible B.1.1.7 variant which has accounted for more than half of the total number of cases and deaths since the start of the pandemic. According indonesian ministry of health, it detected two variant COVID-19 cases first identified in India. Indonesia has suspended issuing visas for foreigners who have been in India in the past 14 days.

In Malaysiafirst case of coronavirus variant identified in India was recorded in particular in Algeria which recorded six cases of the variant in the coastal province of Tipaza.
