Deep gratidude to @angie_rasmussen @linseymarr @SaskiaPopescu @Don_Milton @Ryan_Mac_Phd @jljcolorado @bencowling88 & Dr. Hitoshi Oshitani. They work so hard to communicate the science with the public & it's been an honor to try to put it all together.

Correctly understanding the specifics of airborne transmission of COVID is *really important* because it changes many things about our guidance on masks and distancing like who should mask? When? How? When is six feet not enough? Should we mask outdoors? https://www.theatlantic.com/health/archive/2020/07/why-arent-we-talking-more-about-airborne-transmission/614737/ …pic.twitter.com/Q2i5QPOTtc

Yes. Taking short-range aerosols plus superspreading seriously has implications for almost every aspect fighting COVID. Japan, which long took airborne transmission seriously, does contact-tracing differently (cluster-busting) exactly for this reason.https://twitter.com/bendadams/status/1288858770983006208 …

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 …

Shelly Miller, PhD @ShellyMBoulder(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).Show this thread5 replies 62 retweets 218 likesShow this thread -

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

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. This is why focusing on the right science matters. h/t

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

Maybe the filtration is enough to knockout transmission, but this XKCD always comes to mind on that topic. https://twitter.com/ryanlanciaux/status/1233942095985086465?s=21 …https://twitter.com/ryanlanciaux/status/1233942095985086465 …

There is, however, a striking lack of plane outbreaks despite months of flying with no masks and no measures, really. I'm all for masks and empty middle seats (hah!) but it's pretty clear that the air recycling *plus* filtration *plus* vertical directionality is doing something.

Is the air recycling and filtration standard on all planes?
