CLEARING AEROSOLS FROM ROOMS: Now that aerosol transmission of the coronavirus is established, the big question is how to disperse aerosols quickly enough. Well, this video explains it all. Thread 
of latest evidence. #COVID19
2) Indoor air ventilation is needed to clear aerosols & reduce airborne transmission risk. Video demonstrates time needed to clear smoke from room:
2 opposite doors: 7 min
1 door: 45 min
1 door w/ fan: 21 min
1 door w/ 2 fans circulating: 12 min
2 doors/windows best

3) Here is the latest evidence from the Diamond Princess supporting aerosols as a major transmission route. https://twitter.com/drericding/status/1288837200621318144?s=21 https://twitter.com/drericding/status/1288837200621318144
4) here is a MUST read piece on aerosols by @linseymarrāshe highlights:
In a peer-reviewed study, researchers at the University of Nebraska Medical Center found that aerosols collected in the hospital rooms of Covid-19 patients contained the coronavirus. https://www.nytimes.com/2020/07/30/opinion/coronavirus-aerosols.html#click=https://t.co/9n1toDYCnN

5) ...āThis confirms the results of a study from late May in which Covid-19 patients were found to release SARS-CoV-2 simply by exhaling ā without coughing or even talking. The authors said finding implied that airborne transmission āplays a major roleā in spreading the virus.ā
6) Here is the link to the study demonstrating virus aerosol collected from the air can infect cells: https://twitter.com/drericding/status/1288535783700336642?s=21 https://twitter.com/drericding/status/1288535783700336642
7) āAs we cough, sneeze, talk, breathe, we release droplets (small fluid particles) and aerosols (smaller fluid particles) into the air. The transmission of SARS-CoV-2 via aerosols matters much more than officially acknowledged.ā (above piece)
8) And because of microdroplet aerosols can be stable in a room for 20 min - 4 hours (according to @kprather88), we needs to realizing that 6 feet rule isnāt enough to protection anymore from aerosols. https://twitter.com/drericding/status/1286854902225031171?s=21 https://twitter.com/drericding/status/1286854902225031171
9) And while large droplets do indeed fall to the ground quickly, the small microdroplets do not. And up to 16 hours stable in stagnant air according to experts. Here is an animation. https://twitter.com/drericding/status/1283066221366312961?s=21 https://twitter.com/drericding/status/1283066221366312961
10) Poor ventilation in places has likely caused outbreaks. One asymptomatic child at an in-home daycare led to a #SARSCoV2 outbreak that has (so far) infected 16 in 4 families, incl 6 kids at the child care, 1 sibling, 7 parents, & 2 grandmas. #COVID19 https://www.syracuse.com/coronavirus/2020/07/at-least-16-sick-after-coronavirus-exposure-at-dewitt-in-home-day-care-take-this-seriously-stay-home-if-sick-at-all.html#click=https://t.co/3Eru1rx60Y
11) How major is aerosols anyway? One expert estimates āmajority (>50%) of the spread is through aerosolsā. 
Princess 
also supports likely. Expert aerosol scientist @jljcolorado lays it out. He investigated WA choir singing outbreak too. #COVID19 https://twitter.com/jljcolorado/status/1282184696466554883?s=21 https://twitter.com/jljcolorado/status/1282184696466554883

12) Good review article on aerosols and ventilation most importantly. https://www.theatlantic.com/health/archive/2020/07/why-arent-we-talking-more-about-airborne-transmission/614737/
