Dominant Transmission of COVID is Airborne, Say Experts
Airborne transmission of COVID-19 is not simply possible, there is 'consistent, strong evidence' that this is the 'dominant' method by which it spreads.
LONDON — Airborne transmission of COVID-19 is not simply possible, there is "consistent, strong evidence" that this is the "dominant" method by which it spreads, according to a new review article published in the Lancet medical journal.
In scientific briefings made available on its website, the WHO defines aerosols as being less than five micrometers in diameter and respiratory droplets as being greater than five micrometers in diameter. However, the Lancet states that droplets with diameters of up to 100 micrometers may be able to spread the virus through the air.
Foremost among its justifications for this claim is the role of superspreader events in spreading COVID-19. These events, whereby a large number of people in the same area are infected with the virus, cannot be explained by close range respiratory droplets or fomites, the review says.
