Scientists call for ‘calm’ against the new strain of nCoV


British officials are alarmed that the new strain of nCoV has emerged per 1,000 people, however, there is no evidence that it works differently from other known strains.

British Prime Minister Boris Johnson announced on December 19 that millions of British people would have to cancel their Christmas and indoors plans as the new strain of nCoV is spreading so rapidly. British Health Minister Hancock stressed that the situation is “deadly serious” and the possibility of “getting out of control”.

However, British scientists believe that the new variant does not cause more serious problems than the old strains, but it is 70% more contagious.

Like other viruses, nCoV is always evolving, which is not surprising. Extensive vaccination of Covid-19 vaccine can trigger enormous pressure, causing the virus to evolve in a mutation direction to evade an immune response. This, can make the fight with nCoV lengthy.

However, some experts urge people to calm down as it has taken many years for the virus to evolve enough, rendering current vaccines powerless.

“It is impossible for a single catastrophic mutation to suddenly come out that causes all immunity and antibodies,” said Jesse Bloom, an evolutionary biologist at the Fred Hutchinson Cancer Research Center in Seattle. It was a process that lasted for many years, requiring the combination of a lot of virus mutations. It wouldn’t be like a switch with two on-off modes.

Outside the UK, experts discovered a similar mutation in South Africa. Scientists have recognized that human behavior is the cause of the epidemic. How the mutation affects the transmission of the virus is not exactly quantified.

The virus is able to completely evade the immune system, requiring the accumulation of a series of mutations. Each mutation helps the virus dodge some of the body’s defenses. Some viruses, like the flu, accumulate those changes relatively quickly. But others, like measles, have hardly any changes.

Emma Hodcroft, a molecular epidemiologist at the University of Bern, Switzerland, said: “Vaccinate about 60% of the population within about a year and reduce the number of infections significantly, helping to reduce the risk of the virus. mutated “.

According to the World Health Organization (WHO), there is no evidence that this new strain behaves differently from the recorded strains.
