On Saturday, Prime Minister Boris Johnson put the UK’s toughest coronavirus restrictions in place since the first lockdown in March, banning holiday gatherings from more than one household and closing all non-essential businesses in a zone that spans greater London and Much of it encompasses the South East of England. Cause for Caution is a new COVID-19 mutation active on the island that has helped the rate of new infections nearly double in the past two weeks

“This virus spreads more easily,” says the UKPatrick Vallance, chief scientific advisor, said Saturday, “And so more action is needed to stay in control”

Neighbors Agree While the virus strain is not expected to be resistant to vaccines introduced earlier this month, France, Spain, Italy and several other European nations have temporarily banned travel from the UK as scientists try to find out more Experiencing the Mutation Below is an introduction to the health and policy implications of the development in question

The variation found in the U K., known as “VUI – 202012/01”, was first identified there in mid-September, according to the World Health Organization. Its mutations have appeared on the genetic material that controls the spike protein, causing COVID and other similar viruses to invade host cells and cause infection can

According to the UKPatrick Vallance, Chief Scientific Advisor, has 23 changes in the virus’s genetic material, an unusually large number that appears to be helping it to spread faster. British officials have now estimated that “VUI – 202012/01” is up to 70 percent more transmissible is – a number based on modeling but has not yet been confirmed in laboratory experiments.While there is no evidence to date that the strain causes more intense disease or leads to a higher death rate, faster transmission means more cases, which is higher Hospitalization rate can lead

In general, viruses tend to make small genetic changes as they move through a host population. “Viruses that encode their genome in RNA, such as SARS-CoV-2, HIV, and influenza, tend to make mutations quickly, though they are copied into their hosts because enzymes that copy RNA are prone to error, “explains nature author Ewen Callaway

Scientists have tracked minor changes in the COVID-19 genetic code since the pandemic began, and so far at least 1000 variants discovered However, the alteration in the spike protein found in south-east England is one of the first coronavirus mutations to make it more contagious

As the Wall Street Journal notes, this isn’t the first time COVID mutations have resulted in a more transmissible strain of virus:

In July, scientists described a variant that over time displaced an older strain of coronavirus to become the dominant strain in the global pandemic.Experiments showed that the variant known as G614 replicated faster but was just as susceptible to antibodies appeared to be targeting the earlier strain and not associated with any more severe disease

“We assume by all scientists that the vaccine response for this virus should be appropriate,” said Patrick Vallance, UK the chief advisor to the government said in a briefing on Sunday Therefore, the strain that has stalled the south-east of England will begin on Aug. December did not affect vaccination efforts

Microbiologists speaking to NBC News, however, shared concerns that the virus might eventually grow to become resistant to vaccines “Although it may not actually be resistant, it may not require as many changes afterward, until it gets there, “said Ravindra Gupta, professor of clinical microbiology at the University of Cambridge Simon Clarke, associate professor of cellular microbiology at the University of Reading, said the COVID vaccine may eventually become like a flu shot and require an updated version every year

On Sunday, the Netherlands and Belgium became the first nations to stop air traffic from the United Kingdom. Soon Austria, Germany, Ireland, Spain, Italy and Israel were added, and the French ban appears to also apply to travel across the English Channel on Monday the European Union will meet to discuss a coordinated effort

Before Boris Johnson announced the new restrictions on Saturday, the US was already blocking travel for most non-Americans Citizen who had recently been to UK, Ireland, Brazil and 26 other European nations, according to a report by the Telegraph the day before Johnson’s announcement, President Trump was considering lifting that ban – although the lockdown could alter the calculation of that decision

Scientists in South Africa have discovered a strain that divides one of the UK coronavirus mutations in up to 90 percent of the samples that have been genetically sequenced since mid-November, according to molecular epidemiologist Emma Hodcroft, there is evidence that the two variations are separate Although the variant has not been linked to more severe cases, it has been linked to higher viral loads on swab tests, meaning it is also more transmissible

South Africa, the hardest-hit nation on the continent, is currently experiencing a second wave, driven in part by this more virulent strain and in part by behaviors that have undermined public health measures throughout the pandemic – including one recently at a beach town on the Indian Ocean where over 1000 participants tested positive for COVID-19 At a WHO meeting earlier this month, scientists reported that the new variant accounted for 80 to 90 percent of infections in South Africa
