      A study from Korea showing why indoor dining is unsafe and why airborne transmission matters. Case B infected case A from 6.5m (~21 feet!) away in *just five minutes*, and case C from 4.8m (15 feet!). Footage shows no interaction—and only those in line of air flow got infected.pic.twitter.com/Yw3Gb8INWP

      The important question though isn't whether this is possible but how frequent it is. It doesn't seem like this study can answer that. There are countries that took names for tracing purposes from restaurants, so there's no reason a good study with denominators couldn't be done?

      You need proper large N studies for that, meanwhile we still cannot get people to accept the transmission paths highlighted by these studies, i.e. indoor dining is not a good idea.

      Obviously I agree this can make the case that these transmission paths can happen. But using the existence of any reports as the basis for policy decisions would ban outdoor dining as well, along with schools, etc.

      I'm aware of very few documented outdoor transmission events—and we understand mechanisms here—plus we have many studies from schools showing age differences. We do have many restaurant/bar/nightclub transmission events. Proportions are indeed unknown, but we do have an idea.

          It feels like it’s all an odds game... and in this case the odds are in your favor. If we dissected other aspects of life that potentially lead to morality in this same manner we would be lost in the woods. Or maybe we do and I’m just missing it.

          Why do you think we banned smoking indoors? Or have spent decades trying to improve air quality? Every iteration of new cars becomes a little bit safer to crash in or be hit by, food is constantly under scrutiny for effects on health. We do this all the time for loads of reasons.

          I don't mean to suggest that we don't have reason to think indoor dining is higher risk; the increased risk of indoor settings seems to be one of the few things that is relatively clear. For me individual reports like this are a small part of the picture though. 1/

          In particular the risk of cross-table transmission does seem unclear currently, rather than transmission between people at the same table, or staff in close contact with customers. Highest risk environment not within-table is likely the kitchen, whether for takeout or dine-in./2
