Health Secretary Matt Hancock (Matt Hancock) said in the house of Commons on Monday that researchers are urgently investigating whether the new version of the new coronavirus is more contagious than the previous version, even if he is also trying to reassure members about the risks of the new version.
"there is currently no indication that this variant is more likely to lead to severe diseases and the latest clinical recommendation is that this variant is unlikely to lead to vaccine ineffectiveness," Hancock said.
more than 1,000 cases of new variations of infection have been identified, mainly in southern England, and the WHO (who) has been alerted.
"we do not know to what extent these cases are caused by this change," Hancock added, "but regardless of the cause, we must act promptly and decisivelyControl the fatal disease while carrying out vaccination work. "
although the SARS-CoV-2 virus, which causes a new form of coronavirus pneumonia (COVID-19, i.e. 2,019 coronavirus disease), has been mutating, only one variation has previously been found to alter the nature of the infection, according to virologist.This is the so-called 614G strain, which largely replaced the 614D strain that prevailed in the first few months of the epidemic.
Alan Wilson, director of the Institute of Biomedical Science, told the financial times that he began to hear" rumors "about the new strain on Sunday evening.For scientists, the key issue is whether the new crown virus detection currently used can detect new variations and whether people infected by the early strains have the same level of protection for the new variations.
Wilson said that the new crown virus test is usually able to detect different viral subtypes, which appears to indicate that they can detect new variations, but it may take several weeks to test a sufficient number of infected people to determine how the current test will respond.
whether the new variation means that those who are immune - whether from vaccination or from previous infections - will no longer be protected, Wilson added, adding that it will take" a few months "to determine."We are cautiously optimistic that this will not be a major issue for us."
professor Alan Mcnally, an expert in microbial genetics at the University of Birmingham, said he was "working hard" to characterise the new strain and understand its origin."It is important to maintain a calm and rational view of the strain, as it is a normal evolution of the virus, and we expect new variations to emerge and disappear over time."
" it's not the time to worry about this new variation, but I salute the monitoring measures in the UK that have allowed the new variation to be discovered quickly, "Professor Mcnally added.
another variation, 20A.EU1, was identified in October as the rapid spread of farm workers from Spain to most of Europe.Each variation has its own genetic characteristics and can be traced back to its origin.
according to Andrew Davidson, a virologist at the University of Bristol, 614 is so far considered to be the only variation that affects viral behavior.This variation is considered to "enhance the infectious ability of the virus through this variation" and has become "the main variation in many countries"."However, many studies have shown that this strain does not lead to more severe diseases."
