When maskless people interact, passive listener more prone to infection: Study | India News
BENGALURU: New computer simulations on how speech droplets or aerosols move in the air space between interacting people by researchers from the Indian Institute of Science (IISc) and their collaborators show that the risk of getting infected was higher when one person acted as a passive listener and didn’t engage in a two-way conversation.
“Factors like the height difference between the people talking and the quantity of aerosols released from their mouths also appear to play an important role in viral transmission,” the researchers, from IISc’s department of aerospace engineering (DAE), and collaborators from the Nordic Institute for Theoretical Physics (NORDITA), Stockholm and the International Centre for Theoretical Sciences (ICTS), Bengaluru, noted.
Having understood that when a person sneezes or coughs, they can potentially transmit droplets carrying viruses like SARS-CoV-2 to others in their vicinity, the questions they wanted to answer were: Does talking to an infected person also carry an increased risk of infection? How do speech droplets or “aerosols” move in the air space between the people interacting?
Pointing out that while in the early days of Covid-19 experts believed that the virus mostly spread symptomatically through coughing or sneezing, the researchers said, soon, it became clear that asymptomatic transmission also leads to the spread.
