Bengaluru, Mar 06: Multilayer masks are most effective at preventing aerosol generation, says a new study conducted by a team led by researchers at Bengaluru-based Indian Institute of Science (IISc). The study was carried out in collaboration with scientists in UC San Diego and University of Toronto Engineering.
According to IISc, when a person coughs, large droplets (>200 microns) hit the inner surface of a mask at a high speed, penetrate the mask fabric and break up or atomise into smaller droplets, which have a greater chance of aerosolisation and thereby carrying viruses like SARS-CoV-2 with them.
