A Group Of Researchers Call To Continue Strict COVID-19 Measures To Reduce Newer Strains

Washington: 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.”

Humanity 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 animal 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 animals 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 animal species might also be necessary to curb the spread of the infection.

NDTV – Dettol Banega Swasth India campaign is an extension of the five-year-old Banega Swachh India initiative helmed by Campaign Ambassador Amitabh Bachchan. It aims to spread awareness about critical health issues facing the country. In wake of the current COVID-19 pandemic, the need for WASH (Water, Sanitation and Hygiene) is reaffirmed as handwashing is one of the ways to prevent Coronavirus infection and other diseases. The campaign highlights the importance of nutrition and healthcare for women and children to prevent maternal and child mortality, fight malnutrition, stunting, wasting, anaemia and disease prevention through vaccines. Importance of programmes like Public Distribution System (PDS), Mid-day Meal Scheme, POSHAN Abhiyan and the role of Aganwadis and ASHA workers are also covered. Only a Swachh or clean India where toilets are used and open defecation free (ODF) status achieved as part of the Swachh Bharat Abhiyan launched by Prime Minister Narendra Modi in 2014, can eradicate diseases like diahorrea and become a Swasth or healthy India. The campaign will continue to cover issues like air pollution, waste management, plastic ban, manual scavenging and sanitation workers and menstrual hygiene.
