AIRBORNE—at long last—the CDC just finally acknowledges that people can be infected with #COVID19 through aerosol airborne transmission, especially indoors with inadequate ventilation.

this is HUGE and been long delayed. But glad it’s now CDC official. https://www.washingtonpost.com/health/2020/10/05/cdc-coronavirus-airborne-transmission/

2) This follows Dr Fauci recognized this thanks to the direct advocacy aerosol experts @kprather88 along with a host of aerosol scientists @Don_Milton @CorsIAQ @jljcolorado @linseymarr @ShellyMBoulder, along with @FAScientists advocacy of @AliNouriPhD @mykfish et al. below. https://twitter.com/drericding/status/1309829079152111616

3) And indeed all the evidence lines up for aerosols. In fact, @jljcolorado and many others think aerosol is likely the predominant form of #COVID19 transmission.

4) To be clear, the coronavirus is MOST DEFINITELY aerosol and airborne. Special evidence detailing all the evidence and reasons why and how we know. If anyone doubts - use this thread below to debunk anyone who says it’s not airborne. https://twitter.com/drericding/status/1308008060854599686

5) Thus, ventilation is key, in addition to high filtration with HEPA or MERV13+ higher air filters. Ventilation is key:

THE SOLUTION TO POLLUTION IS VENTILATION. Here is how to disperse it swiftly in a room. Room air clearance rate is key. #COVID19

6) The early Biogen superspreading conferences Boston in March was also a tell tale sign of airborne aerosols. Great video explainer by @kprather88 with @DrLaPook.
