New coronavirus strain in UK: How rapidly has it spread?.

On Monday India suspended all flights from and to the UK until December 31, amid concerns about a new variant of SARS-CoV-2 that is “spreading & growing rapidly” there. Several other countries, too, have suspended UK flights and imposed travel restrictions..cta text.What are these concerns leading to travel restrictions?Last week, the new SARS-CoV-2 variant was revealed to be the reason behind the rapid surge in Covid-19 cases in South and East England. It is being referred to as VUI (Variant Under Investigation) 202012/01, or the B.1.1.7 lineage.“Over the last few days, thanks to our world-class genomic capability, we have identified a new variant of the coronavirus, which may be associated with the faster spread in the South of England,” UK Health Secretary Matt Hancock told the House of commons on December 14.

Preliminary analysis suggests that it is more transmissible than previously circulating variants. COG-UK identified one of these mutations as “N501Y”, in an area of the spike protein that binds to a key protein in the human cell, the ACE2 receptor. This was an indication that the alterations may, theoretically, result in the virus becoming more infectious. “Efforts are underway to confirm whether or not any of these mutations are contributing to increased transmission,” the consortium said..

It said mortality is a “lagging indicator” and it will “continually monitor this over the coming weeks”.PHE has said it does not know yet the mechanism for this increase in transmission. “We know that mutations in the spike protein, the part of the virus that makes it infectious, can change how the virus interacts with human cells,” it said..Read the Latest Agriculture News in Marathi & Watch Agriculture videos on Agrowon.
