Depending on ventilation - aerosols can remain in the air from 20 mins to 4 hours https://twitter.com/DrEricDing/status/1315422604510060544

5. UK Government - "Hands-Face-Space" - mentions aerosol transmission

Time: 1.15 - "smaller droplets called aerosols can stay in the air for some time - especially if there is no ventilation"

6. Evidence (March) - Invite 30 MPs to sit in a crowded, poorly ventilated indoor classroom with no social distancing and no face masks. Topic COVID Aerosol Transmission - watch this short 6 min video and see how FAST the classroom empties

7. CDC FAQ (9 Oct) says, "It spreads through respiratory droplets or small particles, such as those in aerosols.. These particles can be inhaled...and cause infection. This is thought to be the main way the virus spreads."

SARS-CoV-2 may also spread through aerosols in the absence of aerosol-generating procedures, particularly in indoor settings with poor ventilation. https://www.who.int/news-room/commentaries/detail/transmission-of-sars-cov-2-implications-for-infection-prevention-precautions

9. John Snow Memorandum (15 Oct) - Scientific consensus on COVID-19 pandemic: we need to act now.
@adamhamdy
SARS-CoV-2 spreads through contact (via larger droplets and aerosols), & longer-range transmission via aerosols, especially..ventilation is poor.

Aerosols are the tiny particles of liquid and material that float around in our environment. When they come from an infected person, they may be a significant source of coronavirus transmission.
