Claims were made of the virus being manufactured in laboratories and then shipped to nations to let loose on their populations. Conspiracy theories competed with each other like racy Hollywood plots at the box office. In a paper published on March 17, Nature Medicine busted the theory of a lab-cultured SARS-CoV-2. The paper, The proximal origin of SARS-CoV-2, by Kristian G. Andersen, Andrew Rambaut, W. Ian Lipkin et al, made it clear that this was a case of zoonoses.
Why Nature Medicine claims Sars-Cov-2 is a naturally evolved virus rather than being manufactured in a lab?
According to the United Nations Environment Programme (UNEP), 60% of all infectious diseases in humans are zoonotic, and about 75% of all emerging infectious diseases are zoonotic in nature. Emerging pathogens are more likely to be viruses, than any other kind — bacteria, parasites, fungi — and are more likely to have a broad host range.
Why are zoonotic diseases prevalent?
Why to preserve the ecosystem?
What about the plant kingdom?
Is ‘One Health’ the solution for this pandemic?
According to the World Health Organisation, ‘One Health’ is an approach to designing and implementing programmes, policies, legislation and research in which multiple sectors communicate and work together to achieve better public health outcomes.
The areas of work in which a ‘One Health’ approach is particularly relevant include food safety, the control of zoonoses, and combating antibiotic resistance (when bacteria change after being exposed to antibiotics and become more difficult to treat).
The concept helps practitioners understand disease determinants, manage risks and optimise interventions.
Climate scientists argue and epidemiologists agree that ‘One Health’ is a key principle for the control of zoonotic diseases, antimicrobial resistance, food safety and vector-borne diseases.
Way ahead:
The UNEP calls for strong global stewardship of nature and bio-diversity. Additionally, developing sharper, reliable early warning systems (for diseases), and a ‘One Health’ approach may be the guides for the road ahead.
