COVID-19 is primarily airborne; safety protocols should change urgently: Lancet Report

A report published in the journal The Lancet has quashed the popular scientific view that SARS-CoV-2, which causes COVID-19, is not an airborne pathogen. The authors of the report have immediately called for changes in safety protocols while listing lists ten reasons why SARS-CoV-2 is transmitted primarily by the airborne route.

Here are the ten reasons:

1. “Superspreading events account for substantial SARS-CoV-2 transmission; indeed, such events may be the pandemic’s primary drivers,” they said. Detailed analyses of human behaviours and interactions, room sizes, ventilation, and other variables, the authors said, are consistent with airborne spread of SARS-CoV-2 and the same cannot be adequately explained by droplets or fomites.

2. Long-range transmission of SARS-CoV-2 between people in adjacent rooms but never in each other’s presence has been documented in quarantine hotels, the paper said.

3. The experts argued that from 33 per cent to 59 per cent of all Covid-19 cases could be attributed to asymptomatic or presymptomatic transmission of SARS-CoV-2 from people who are not coughing or sneezing. They said this supported a predominantly airborne mode of transmission.

4. Transmission of SARS-CoV-2 is higher indoors than outdoors and is substantially reduced by indoor ventilation.

5. The paper said nosocomial infections (those that originate in a hospital) had been documented even at places where healthcare professionals used personal protective equipment (PPE) designed to protect against droplet but not aerosol exposure.

6. The experts said viable SARS-CoV-2 has been detected in the air. In laboratory experiments, SARS-CoV-2 stayed infectious in the air for up to 3 hours. They rejected the argument that SARS-CoV-2 was bit cultivated from air arguing that measles and tuberculosis, two primarily airborne diseases, had never been cultivated from room air.

7. SARS-CoV-2 has been identified in air filters and building ducts in hospitals with COVID-19 patients; such locations could be reached only by aerosols, they said.

8. The experts cited studies involving infected caged animals that showed transmission of SARS-CoV-2 via an air duct.

9. Another argument of the experts was that no study to our knowledge provided strong or consistent evidence to refute the hypothesis of airborne SARS-CoV-2 transmission.

10. Their final argument was that there was limited evidence to support other dominant routes of transmission- i.e. respiratory droplet or fomite.

If the claims made in the report and proven and accepted by the broad scientific community, it could have massive impact on how people fight COVID-19. It may require people to wear masks even inside their homes, possibly at all times.

For the uninitiated, the current scientific view is that SARS-CoV-2 spreads through smaller aerosols that stay suspended in air or through fomites, the surfaces where the virus gets deposited, and could be picked by a healthy person.
