For someone who is open-minded but skeptical that a significant fraction of COVID transmission is happening across large distances (distance is not protective indoors, etc), what is the best epidemiological evidence to make a convincing quantitative case for this? @zeynep, etc.

I agree the evidence suggests that poor ventilation etc makes these clusters relatively more likely than they are otherwise. But I am not sure I've seen good evidence that they actually represent a significant chunk of overall transmission, even with the bad ventilation, etc.

There are many places where we would have the data for contact tracing to pick up long-range transmissions. (Jurisdictions where restaurants take contact information, etc.) But are there cities, etc., that attribute 5-10% of their transmission to these long-distance events?

My understanding was that from the Cruise Chip experience, it was deduced that the virus could spread trough ventilation . Therefore TV studios with artificial ventilation could spread the virus.
