What are the new strains of coronavirus? Why are they dangerous? A scientific analysis
This is a time when the world is paying close attention to the spread of new variants of Covid-19. What are the new strains of the virus? Why are they dangerous? Virologists around the world are paying close attention to these facts. Any virus takes on a different face over time. This is a common feature of the SARS-Covid-2 virus. Thousands of mutations in the coronavirus have occurred since it was first identified a year ago. “A large number of these variants take the form of ‘normal passengers’ and are not affected,” said Dr. Lucy van Dorp, a scientist in the Department of Pathogens at the University of London.
They do not change the behavior of the virus, they only carry the virus,” said Dr. Lucy van Dorp. But at every turn, the virus takes on a different shape, causing it to survive and reproduce. Dr. Lucy Van Dorp points out that “those strains of the virus that are transmitted can increase their frequency in natural selection and form the correct epidemiological settings.” There are differences between the new strain of the newly identified South African 501.V2 coronavirus, which is similar but two strains of the new strain of the coronavirus that is spreading in the UK, known as 202012/01.
There is no evidence that both new varieties of Kovid found in the UK and South Africa are serious pathogens. But the problem is that with the rapid increase in the number of new strain infections, the provision of health care has come to a standstill. Hundreds of thousands of viruses have been subjected to genetic analysis around the world. “While there is no information on the severity of these new strains of the virus, there has been an increase in the number of hospitalizations and mortality, especially as a result of the spread of these corona strains, especially in the elderly or victims of several diseases,” the EU said.
These strains of the virus have a different origin but transmit a mutation of the thin-film spike protein content, which in turn leads to the virus entering human cells. Many people see this virus as the cause of infection. “There are spike genetic variations in the virus strains that are currently spreading in the UK and South Africa, which is why they are so highly contagious,” said Lawrence Young, a professor at the University of Warrick.
But Dr. Jeff Barrett of the Wellcome Sanger Institute in Hingston, UK, puts it this way. “How this spreads so fast is determined by the combination of the virus’s behavior and what we do.”
With the easing and tightening of restrictions, the situation of new strains will change rapidly. There is little room for error in controlling the spread of the virus, ”he said. “However, we have no evidence that the new virus strain can fundamentally avoid masks, social isolation, or other interventions. What we need to do is keep them tight.”
While vaccine distribution is currently in full swing, scientists are struggling to understand the impact on vaccines that respond to spike proteins. Special attention is being paid to the South African variant with various variations of the spike (S) protein. Many experts hope that the vaccine currently being given will have a beneficial effect, at least for a short time. Dr. Julian W Tang, a virologist at the University of Leicester, says that vaccines can be developed in a matter of months, with effective levels against new strains of the virus. Scientists have already begun studies at the laboratory level to find out more about the strains of the Kovid virus that are currently being detected. As it spreads around the world, scientists are trying to capture all the behaviors of the virus.
A virus sample taken from the throat of an infected patient has the ability to isolate and amplify the gene code of the virus. Also, identifying the chemical composition of the virus gives the opportunity to compare the genes and genetic mutations of the virus. “Thanks to such efforts and experiments in UK laboratories, the spread of the virus in the UK was quickly identified as a major concern,” said Dr. Van Dropp.
Professor Julian Hiscox is the Chairman of the World Health and Infectious Diseases Committee of the University of Liverpool. He stated: “Scientists are trying to defeat the virus, but we’re really good at controlling new strains.” Severe ‘lockdowns’ in the short term reduce the number of infected people,” said Professor Julian Hiscox. “Lockdown reduces the number of people infected with the virus and reduces the spread of the virus, which is a good thing.”
However, in the long run, the professor suspects that in the future there will be a pathological situation like the ‘flu’. Then you have to create new vaccines every year to control the condition. “The problem is that with different strains of the virus, they are able to function regardless of the strength of the vaccine, so there is a possibility of a reduction in the virulence of the vaccine,” said Professor Julian Hiscox.
