Talking can spread Covid as much as coughing, finds IISc study

New Delhi, 18/6: When a person sneezes or coughs, can they potentially transmit droplets carrying viruses like SARS-CoV-2 to others in their vicinity? 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?



Answering all these questions is a research team which has carried out computer simulations to analyse the movement of the speech aerosols.


The team includes researchers from the Department of Aerospace Engineering, the Indian Institute of Science (IISc), along with collaborators from the Nordic Institute for Theoretical Physics (NORDITA) in Stockholm and the International Centre for Theoretical Sciences (ICTS) in Bengaluru.
