A reminder about DROPLETS and MICRODROPLETS. 6 feet rule is not enough indoors with now established aerosol based transmission. #MasksOn #COVID19
2) Here is an earlier thread on evidence that air floating Microdroplets are infectious. These microdroplet aersols collected from the air of a hospital ward went to infect cells. https://twitter.com/drericding/status/1285465200502755328?s=21">https://twitter.com/drericdin... https://twitter.com/drericding/status/1285465200502755328">https://twitter.com/drericdin...
3) Experts also earlier admits that aerosol transmission could be a potential dominant pathway for #COVID19 infection. https://twitter.com/drericding/status/1285603683531665408?s=21">https://twitter.com/drericdin... https://twitter.com/drericding/status/1285603683531665408">https://twitter.com/drericdin...
4) Here is an animation of MICRODROPLET aerosols that do not get pulled down by gravity like large droplet (aka ‘ballistic’ droplets) do. And it stays in air for 20 min to 4 hours with normal building airflow. But 16 hours in stagnant air. https://twitter.com/drericding/status/1280708110127181824?s=21">https://twitter.com/drericdin... https://twitter.com/drericding/status/1280708110127181824">https://twitter.com/drericdin...
5) This study indicates up to 16 hours in stagnant air. It’s a research paper published in a CDC manager journal

6) All the aerosol data indicates we should all wear masks. Furthermore remember that mask now also found to reduce severity of illness, should you somehow get it- ie more likely asymptomatic. Because of lower dose—explained in detail here. #COVID19
