    BIOON/ -- Researchers say continued mutations in coronaviruses are unlikely to change their potency or infectiousness, despite recent research finding a more toxic coronavirus strain, after researchers from Los Alamos National Laboratory claimed in a preprint edit that they had identified a new strain of the virusThe researchers say the mutation in the virus's protein protrusions could make the strains of the virus, which are currently circulating in Europe and the United States, perhaps more toxic than those that appeared in China late last yeartherefore, the mutated protoprotein may be an urgent concern for researchers, and the virus, which began spreading in Europe in early February, quickly becomes a major cause of disease as it enters new areasThe researchers say any new strain could have an impact on the efficacy of the currently developed treatment or vaccine against COVID-19, which has since made headlines but has also raised alarm among many disease experts, largely because the theory of increased transmission has not been tested in the laboratoryphoto source: medicalxpress.com
    Harvard TWilliam Hanage, a researcher at the HChan School of Public Health, said the virus variant may have been very lucky and was introduced out of Wuhan very earlyIn essence, viruses have been constantly mutated, which doesn't seem to make much sense, and mutations are the result of genome replicationLike the virus that causes COVID-19, it is essentially a bunch ofgenetic-DNA, which contains instructions that can build their own copyBecause viruses require the host body's cells to replicate, they make many small errors in the RNA replication process, leading to mutationsResearchers at the University ofLondon have found that at least 198 sites in the SARS-CoV-2 genome have been mutated, consistent with events in many parts of the world where the virus is spreading and locally, and researchers say there is speculation about more toxic strains Unlike other viruses such as HIV, SARS-CoV-2 does not appear to have a high mutation rate, and there is no convincing evidence that mutations have a significant impact on how the virus affects the health of the human body previous study published in the international journal Virus Evolution, scientists from the University of Glasgow said they had found only one type of virus, and by analyzing the genetic sequence variations of widespread in the SARS-CoV-2 virus genome, evolutionary analysis suggests that there appears to be no evidence to cure why multiple types of viruses are currently spreading most important, people don't have to worry about mutations in viruses, which are normal and expected when they pass through a group of people; while mutations don't mean THAT COVID-19 is more powerful or contagious, experts stress that it's still important to track its evolution; sequencing more virus genomes will help researchers understand the mechanism swayed by the virus and observe whether minor changes have a significant impact on virus behavior, and how future researchers will develop effective vaccines The issue of mutations seems to be less important than testing or treating infected people; at the cost of humans, the virus has done well enough to plant in humans, and researchers don't think the virus will get any worse in the short term (biovalleybioon.com) References: Virus mutations unlikelyly to mean stronger strain: experts
