A new form of corona has been caught behind the rapid corona infection in southeast England. However, this is not the first time the virus has changed since the onset of the epidemic.
There have been previous changes in the genetic material of Kovid-19. These changes also alter the virus’s ability to transmit.
What should we be worried about?
While mutations may seem scary in the case of viruses, this would be a bad thing; Nothing like that.
Every virus changes. This is because when it communicates with a host, it makes new copies of itself that can infect other cells. Some changes occur as RNA viruses, such as coronaviruses, are copied.
In some cases, this mutation can also weaken the virus. In many cases, these mutations can make the virus more contagious or cause more serious disease.
Kovid-19 is changing its appearance every week. Many mutations have no effect on the virus. This latest adaptation found in the UK, however, helps the virus spread faster. However, it has not yet reached the critical stage of reversing the effects of the vaccine.
Sky News science correspondent Thomas Moore said the change was “not entirely unusual”.
Kovid-19 still has at least seven large groups or strains that are compatible with its human host. In December 2019, the main stress in the Chinese city of Wuhan is known as El stress. Later it reaches the S, V and G strains in stages.
The highest incidence of strain G has been observed in Europe and North America. However, the spread of the virus in the region has slowed the spread of the virus. As a result it again changes to GR, GH and GV stresses.
The main el strain has been in Asia for a long time as many countries, including China, have closed their borders and banned the movement.
Several other small mutations are placed together in strain O.
Danish authorities were concerned about the trend of the virus found in 12 people associated with mink farming. They feared that this mutation might interfere with the effectiveness of any vaccine. Because it happened on the spike protein. Under the circumstances, the government took the initiative to kill 18 million minks in the country. Danish health officials, with the help of the armed forces, buried the dead mink in a military area. Authorities also imposed a month-long lockdown in the northwest of the country.
What are the most common strains in the world?
G. strains are now in a strong position worldwide. In particular, it has similarities with the prevalence of Europe, including Italy.
The most commonly seen variant is the D714G. Some experts say that this version has made the virus more contagious. However, there is conflict with data from other studies with this.
Meanwhile earlier stresses such as the original L stress and the V stress are slowly disappearing.
An analysis by the news agency Reuters found that Australia responded quickly to the epidemic. Has initiated effective social distance. As a result, the country has been able to overcome the then LOS tension. However, subsequent new tensions from outside the country led to new infections.
G, GH and GR strains have been growing in Asia since the beginning of March, more than a month after spreading to Europe.
Will the mutation affect the vaccine?
So far, experts have not found any version that can reduce the effectiveness of any vaccine. The speed of virus transformation has also slowed down.
Reacting to the new stress found in Britain, England’s Chief Medical Officer, Professor Chris Whitty, said it would be “surprising” if the vaccine had an effect. He also stressed the need to get more solid data quickly.
Researcher Federico Giorgi of the University of Bologna coordinated a study on the strain of Kovid-19. “Stork-cov-2 coronovirus is probably already in a favorable position to infect humans,” he told Science Daily.
“The medical system we are developing, including the vaccine, can be effective against all viral strains,” he said.
As suggested by a team of scientists from several institutions, including the University of Sheffield and Harvard University, G strains can be better targets for a vaccine. This is because the surface of these strains contains more spike proteins.
“We still need to be vigilant and follow any new changes,” said researcher Lucy Van Dorp of the Genetics Institute of University College London.
He says that the best way to ensure the vaccine’s effectiveness is to reduce the risk of spreading the infection and replace it.
