In a third study, 1 family (A) from Wuhan infected two other fams (B & C) in an air-conditioned, windowless restaurant. The families overlapped by 50-70 mins in seating. 83 ppl in total ate lunch that day on this floor, over 15 tables. Only 5 in families B & C were infected 9/23

If concerns about airborne transmission bear out, changes to air circulation systems/flows/patterns & filter qualities may make places safer. In the short term, advice on masks & doing all possible to aid air exchange with the outside may make a real difference. 20/23

The fact that it feels like this is something less easy to tackle (not simply putting 2m lines on a floor, or sanitising table-tops) makes it harder to talk about, I think. We don't want to have more to be worried about!

But wishing won't make a possible risk go away.

Instead, we should empower our reopening strategies to take into consideration these possible risks, & let people take put into their calculations about where & when they go. So they can make informed decisions.

Is there any evidence to suggest indoor/room HEPA air filters reduce the risk of transmission?
-
HEPA filters are designed to filter out virus particles this small, so in theory they should work. Here's an article about it.https://www.consumerreports.org/air-purifiers/what-to-know-about-air-purifiers-and-coronavirus/ …

Stop indoor activities with brutally hot summer and monsoon rains. What BS recommendations, continues pseudo-science 'no knowing' epidemiologists/virologists. It will take 10 years to understand SARS-2 even then they will know nothing, zero skin in the game.

Indoor environment + lots of people + exposure for more than 30 minutes = no thanks If I have a choice I can wait
