These the results of a Stanford-UC-Santa Barbara study released on the online pre-print server medrixiv.org. Aerosols form when virus-contaminated droplets dry into a fine fog that travels further than the so-called 6 foot safe distance, remain aloft longer, and travel deeper into an unsuspecting person’s lungs increasing their chances of a CoVid infection. To be safe, wear a mask with an N95, KN95, or a HEPA H12 filter and avoid remaining closer than 30 feet from others talking, screaming, or singing. The take home point : if you’re in a warm dry climate such as the Southwestern states or in any overheated room, a multi-layered cloth mask and the usual distancing may not protect you. https://www.medrxiv.org/content/10.1101/2020.05.24.20111963v2.full.pdf #covid #aerosol #droplet #n95 #kn95 #hepa
