London, October 28

Aerosol microdroplets, which are tiny particles that linger in the air longest after we talk, cough, or sneeze, may be ineffective in spreading the virus that leads to Covid-19, according to a new study.

The results of the modelling study, published in the journal Physics of Fluids, noted that aerosol transmission of the novel coronavirus SARS-CoV-2 in confined spaces is not very efficient.

“If someone enters a space even a few minutes after a mildly symptomatic carrier of the coronavirus has coughed in that area, the probability of infection is rather low,” the researchers, including those from the University of Amsterdam in The Netherlands, noted in a statement. It is even lower if that person was only talking, they added. — PTI
