      There is urgent need for practical guidance for schools and other indoor spaces. For now, see thread from an excellent scientist. Lack of official guidance means there is a lot of snake oil in this space. Basic HEPA filters work, though. See for details->https://twitter.com/CorsIAQ/status/1288739096148336642 …

      16/ The activated carbon is harmless, but does little to remove particles & is usually insufficient in mass to remove VOCs/odors. Not needed. Remember, basics! Aim for a portable air cleaner with a HEPA filter & CADR (for smoke) > 300 cfm (see above)

      (1/2) Are searching for an air cleaner? 1st, I recommend HEPA only for COVID risk mitigation indoors. Want to treat a 600 sq ft room? FYI an air cleaner with a CADR of around 400 cfm will give you 5 air changes of particulate-free air (assuming an 8 ft ceiling).

      Yes, there is an excellent detailed spreadsheet with different places/scenarios (class/subway/campus) by @jljcolorado that the more engineering-oriented can play with.

      Great article. Is there an app or web based risk estimation tool to help individuals assess building and ventilation risk? Yes, I know the government should be doing this, but *looks around*

      One implication: We should have found a way to honor John Lewis without endangering the many vulnerable people in that room. Hopefully they have high CADR HEPA filters or someone checked the ventilation specs. It's the speaker that's emitting the aerosols. https://twitter.com/Pinboard/status/1288881445876822017 …pic.twitter.com/YUdvntka4H

      Let me say this outright: This is unscientific, stupid and wrong. This is incredible. Six months in, how can we be this behind the science? This make so little sense that my head hurts.

      So, this is ridiculous. @Delta is trying to reassure me flying is safe by mentioning... Lysol! Disinfecting! But not mentioning the actually reassuring things: cabin air is recycled every few minutes; cleaned by HEPA filters that can remove viruses and is circulated vertically.pic.twitter.com/cg5aqWgxrq

      Yes very much. I’ve been corresponding with Japanese experts and I have their documents going back to March. They’ve really been on the money. My piece has more on what Japan figure out to do because they took short-range aerosols seriously from the start.https://twitter.com/covidpath/status/1288863784358916097 …

      Thank you! Indeed, ventilation is a layer in the mitigation stack. But understanding the role of short-range aerosols and potential airborne transmission makes how we should do the rest clearer. https://twitter.com/brianbruce7/status/1289039672627396608?s=21 …https://twitter.com/BrianBruce7/status/1289039672627396608 …

      This is a great and very important article. Particularly the idea of layering mitigation—Hand washing, sanitizing, masks, good ventilation — has a significant impact.

      A great article! A random question around the one incident mentioned of a jogger infecting his jogging partner that's classified as a super-spreader event: if only one person was infected by another, does that actually meet the criteria for a super-spreader event and if so, why?

      I wouldn’t classify as a superspreader event but it was weirdly in the database and I didn’t want to mess with it. So I just put in the explanation and trusted the reader to understand.

          Thank you, I will say it tripped me up because it sounds like one person simply infecting another, whereas my understanding of a super-spreader event is many people becoming infected after time doing something together (e.g., outbreak after choir practice).
