      So do we still believe that 1) during the OG SARS epidemic, residents in a different but downwind building acquired virus from an infected building upwind, *and* that 2) risk of outdoors sars-cov-2 acquisition is so low we don't need masks?

      Even before this paper, I had been suspicious of the Amoy Gardens studies for building-to-building transmission, tbh. The geography of the place has a much more parsimonious explanation: shared, packed buses from there and the shared shopping complex.https://twitter.com/zeynep/status/1404120870658977800 …

      I had a lot of back-and-forth with aerosol experts on Amoy Gardens, and I'm not convinced the long-range airborne between buildings via wind theory is that strong. I know the geography of the place, no dedicated subway and shared bus lines which are packed in mornings/evening.

      Absolutely my feelz as well. It doesn't rule out an airborne route of course, but perhaps via shared MTR travel etc

      Yeah. Wind between buildings through open window is a high bar for good reason, going to need more than probabilistic studies of window direction, and will definitely need to look at the more straightforward explanations and at least rule them out somewhat, right? Haven't seen.

          Now that you mention it sth like the bus sounds reasonable - is the raw data of the original study available in order to make double sure that the association between windows/air direction / people in the other buildings was more likely to be just coincidental ?

          Just read the 200 meters scenario and yep, you are right - sounds too much - airborne transmission is a fact but in that particular case it probably occurred in another situation like common transport rather than from l such a long distance
