Dozens of countries have banned travel from the UK in an effort to contain The new alternative to Covid-19 It was first reported in England.
The new mutation is called VUI-202012/01 – the first “variable under investigation” in the UK in December 2020. As scientists search for more information about the variable, its impact is already being felt, with dozens of countries. Restrictions imposed on travelers from the United Kingdom.
Here’s what we know so far about the Covid-19 variant:
What is the alternative and why are officials concerned about this? A variant occurs when the genetic makeup of the virus changes. All viruses mutate over time and new variants are common, including the new coronavirus.
Like other variants, this holds an Easy to track genetic footprintIt is now common in southeast England. This alone does not necessarily mean that the variant is contagious or more dangerous.
But scientists advising the UK government have estimated that this variant could be up to 70% more effective at spreading than others. Peter Horby, President The Advisory Group on New and Emerging Respiratory Virus Risks (NERVTAG), said Monday that experts “now have high confidence that this variable has a write advantage” over other variants.
The World Health Organization said on Tuesday that the changes made to the variable include 14 major mutations, and that some of them “may affect transmission of the virus in humans,” although it added that more laboratory tests are needed.
Where did the variable originate and how was it entrenched? The new variant is believed to have originated in the southeast of England, according to the World Health Organization. Public Health England (PHE) says the back-tracking, using genetic evidence, indicates that the variant first appeared in England in September. Then it traded in very low levels until mid-November.
Chris Whitty, England’s chief medical officer, said on Saturday that the surrogate is responsible for 60% of new infections in London, which nearly doubled in the past week alone.
Several experts also suggested that this new variable could have been amplified by the superspreader event, which means that the current spike in cases may also be a result of human behavior.
Is the new alternative more deadly? There is no evidence yet to suggest that the new alternative is more deadly, according to Whitty and the World Health Organization, although it is too early to tell.
Many experts note that, in some cases, viral mutations that increase transmissibility are accompanied by a decrease in virulence and mortality.
“During virus transmission, those that allow for increased viral“ success ”can be selected, changing the characteristics of the virus over time. This usually results in more transmission and less virulence, says Martin Heibard, professor of emerging infectious diseases at the London School of Health And tropical medicine, told SMC.
