The aerosols are created when breathing, talking and singing. Unlike droplets, they don't fall to the ground quickly, but can stay in the air for a long time and spread throughout the room. Indoor Scientists still believe this is the primary way coronavirus spreads person to person. But more evidence is mounting that the virus could become an aerosol, leading to airborne spread. The other way that coronavirus spreads is likely through a combination of droplets and aerosols.
