CDC has updated its webpage on how COVID-19 spreads to include that the virus can, under certain conditions, spread through airborne transmission of small droplets and particles to infect others more than six feet away. Also provided is a brief on SARS-CoV-2 and airborne transmission.
This makes perfect sense. The fact that we see these large bursts of cases and super-spreading events suggests that this is indeed aerosol spread in addition to droplet. BTW- droplets are larger particles from a few to many microns in size while aerosols are much smaller- like just a micron or so. Aerosols can spread across much larger distances than droplets.
