CoVid IS Primarily Airborne
Vidcast: https://youtu.be/wF60DbdWpDE
CoVid virus is primarily spread by virus riding in mist aerosols rather than in droplets. Harvard epidemiologists draw this conclusion from their study of transmission onboard a Diamond Princess Cruise ship.
The researchers analyzed 132 individual episodes of viral spread and found that large respiratory droplets were responsible about 40% of the time while aerosols transmitted the virus in nearly 60%. Overall, 70% of transmission occurred through the air while only 30% of spread occurs via surfaces.
Bottom line: mask up to block droplets and aerosols. Use or make masks with 3 layers of high thread count cotton or, better yet, N95, KN95, FFP2, or HEPA H13-14 filters. Also distance and wash.
