      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

      So, first note how few such studies we have here. Jealous. This kind of intense shoe-leather epidemiology can give us better answers about potential transmission paths than large=N but less precise tracing which are useful, too but in a different manner. https://jkms.org/DOIx.php?id=10.3346/jkms.2020.35.e415 …pic.twitter.com/vXP5rv2SWb

      The takeaway is the same. Indoors, we should always wear a mask–there is no way to make indoor restaurants or bars safe, including those outside structures that are essentially indoor. Air flow and talking matter and, indoors, neither six feet nor 15 min are absolute protection.

      Folks asking questions! Many of those are answered in the linked study which is exceptionally detailed and well-done. Yes, they had CCTV footage. Yes, they sequenced from the patients to confirm chain. Yes, they actually measured air flow. This is a yeah, it happened, study.

      Look, I really want restaurants to survive. I think they should be helped out until the end of the pandemic and those who can afford to do so can do takeout & tip normally to help keep things going for the moment. Where whether permits, distanced outdoor dining is an option imo.

          I wrote a post for @insight explaining the details of this amazing restaurant study, comparing it to other similar studies, and discuss what we can learn from all this about both indoor dining and airborne transmission. It’s empowering! https://zeynep.substack.com/p/small-data-big-implications …pic.twitter.com/dDDV0CyXvB

          Meanwhile, I'm indoors in court! *sigh* If you've been following the drama, my "ex-pat in Mexico" landlord is *still* trying to evict me through his lawyer. (No worries, I'm also all lawyered-up!) Also only four people out of 20 are wearing N95s: the judge, two lawyers and me.😢

          This is why I find out the wind direction for the day and open one of the office windows depending on the air flow to blow the air away from me.

          Solid science showing airflow and restaurants are high risk for COVID transmission. I love restaurants, so for the love of god, PLEASE print the godamn money and save our restaurants. #wheresthefuckingstimulus

          I'm pretty sure Ionizing systems can be installed into most HVAC systems, though not as efficient with these ductless systems. The ionizers were shown to be effective but they are very expensive.
