The researchers have found out that there is consistent and strong evidence to prove that the SARS-CoV-2 virus, behind the COVID-19 pandemic, is primarily spread through the air. The study has been published in The Lancet journal on Friday.
Previously, it was believed that the virus is largely transmitted through large droplets, which are exhaled by those infected, settle on surfaces and contaminate them. But the new analysis by six experts from the UK, the US and Canada says “The evidence supporting airborne transmission is overwhelming, and evidence supporting large droplet transmission is almost non-existent.”
It is also the reason that public health measures are fail to treat the virus as it is predominantly airborne and leave people unprotected and allow the virus to spread.
In July last year, over 200 scientists from 32 nations wrote to the WHO, saying there is evidence that the coronavirus is airborne, and even smaller particles can infect people.
Jose-Luis Jimenez, from the University of Colorado Boulder in the US said “It is urgent that the World Health Organisation and other public health agencies adapt their description of transmission to the scientific evidence so that the focus of mitigation is put on reducing airborne transmission.”
