A group of researchers is asking governments to consider the continued practice of strict COVID-19 measures and guidelines, as it's the only way to curb the spread and evolution of the newer strains.The evolutionary experts in virology, infectious disease, and genomics at the University of East Anglia (UEA), Earlham Institute, and the University of Minnesota have warned that while governments are negotiating a "precarious balance" between saving the economy and preventing COVID-19 fatalities, stronger action now is the best way to mitigate against more serious outcomes from such virulent strains later.While the deployment of the COVID-19 vaccine is now underway, a major threat to the effectiveness of the vaccine comes from other emerging strains, such as the UK, South Africa, and Brazil variants, and those yet to come.In an editorial for the journal 'Virulence', Professors Cock van Oosterhout, Neil Hall, Hinh Ly, and its editor-in-chief Prof Kevin Tyler said, "continuing public health efforts to encourage vaccination as well as continued use of proper personal protective equipment (PPE), such as proper masking and maintaining safe social interactions, is of utmost importance.""Humty is faced with a new reality. The faster we adapt, the better our long-term prospects. We must stop the evolution and spread of more virulent virus strains now. We, therefore, support public health policies with strict control measures in order to protect our public health system, our individual wellbeing, and our future," the professors added.The researchers look back at what has happened and how best to respond now, highlighting that the roll-out of economic stimulus packages and related activities in many countries appears to have fuelled the rate of person-to-person transmission.As a result, they say at the start of winter the population number of the virus continued from a much higher base than would otherwise have been the case, adding, "By not absolutely minimizing the R number when we had the chance, we extended the pathogen transmission chains, providing more opportunity for it to mutate and evolve into more virulent variants."Additionally, they highlight that an increased virulence - or higher R-value - can also result from the virus evolving the ability to infect people for longer. The authors warn that continued virus evolution in mal hosts, such as cats and mink, followed by transmission into susceptible human hosts, poses a significant long-term risk to public health, suggesting that the vaccination of certain domesticated mals might be important to halt further virus evolution and "spillback" events.Vaccination against a viral pathogen with such high prevalence globally is without precedent and we, therefore, have found ourselves in unchartered waters. However, what we can be certain about is that, as long as the vaccine stays effective, a higher uptake of the vaccines will: reduce the number of COVID-19-related deaths, stem the spread of the transmissible strain of the virus, and reduce the risk of the evolution of other, even more, virulent strains in the future.Furthermore, it is not unthinkable that vaccination of some domesticated mal species might also be necessary to curb the spread of the infection.( With inputs from ANI )Disclaimer: This post has been auto-published from an agency feed without any modifications to the text and has not been reviewed by an editor
