      So much gratitude to @avizvizenilman and @isaacscher who provided incredible research assistance. The piece was fact-checked within an inch of its life over many days, and it's the tip of an iceberg in terms of the research and documentation that went into it.

      Look at this incredible thread by @jljcolorado on the history of aerosol denial/misunderstandings/errors. I put (what I could fit) to highlight this. There's something to say about individual conduct during all this—but also that this is a longer history.https://twitter.com/jljcolorado/status/1391111720526024708 …

      1/ TIME FOR SOME AIRBORNE + DROPLET HISTORY Now that @WHO and @CDCgov have finally accepted *after a year of denial and delays* that airborne transmission is a major mode for COVID-19, it is time to review the history to try to understand why this response was so poor.

      The history matters. Top medical journals still publish errors about aerosol size and biomechanics. Not individual malfeasance. The errors are in the textbooks. Medical doctors are not biophysicists or aerosol engineers. Dismissing relevant expertise has been, sadly, very costly.

      The other part is how causal inference differs by field. Clinical practice rightly uses randomized trials (crucial for drugs and vaccines) but the clear point that the droplet theory didn't do a good job explaining the world as we observed it didn't get the attention it deserved.

      Overlooked but key. Nothing about transmission in this pandemic makes sense except in the light of overdispersion. It alternates between contagious clusters and little to no transmission. This makes causal inference difficult. It fries our assumptions. https://www.theatlantic.com/health/archive/2020/09/k-overlooked-variable-driving-pandemic/616548/ …pic.twitter.com/nygPqC3yzn

      Yes, around the world, to this day. And the constant overuse of bleach etc. is not just a waste of time and resources, it's genuinely unhealthy. "Stop over-disinfecting and start ventilating" has to be a loud campaign, led by WHO & public health agencies.https://twitter.com/Calamitatis/status/1391733545270497282?s=20 …

      Yes, but on the other hand an enormous waste of work-time & resources. Consider the volume of disposable gloves, the plastic containers of lysol & so forth, the crippling requirements of daycare centers, etc. A more timely update could have limited that.

      zeynep tufekci Retweeted Ted Pedersen

      Yes. Some of what we can do is easy/free. Some of it is not, and requires resources and trade-offs (sealed building are energy efficient). Filtering can be an option when dilution is not. Challenge is very real, but still should start from the right place.https://twitter.com/SeeTedTalk/status/1391739250291486727 …

      this all makes a lot of sense. but a lot of schools and universities, for example, are in buildings that don't have great ventiliation, and improving that is costly and not likely to happen. so what do we do?

      Absolutely. I wrote about this in my long piece on the science of it all back in July of 2020. Clorox wipes remained sold out for well into the pandemic, HEPA filters—which absolutely do help—did not. Some places wouldn't even *allow* schools to use them. https://www.theatlantic.com/health/archive/2020/07/why-arent-we-talking-more-about-airborne-transmission/614737/ …pic.twitter.com/CrUInUrLxA

      I kept checking and as far as I can tell, neither HEPA nor MERV-13 filters sold out at any point. But there was all sorts of snake oil—or worse—around as well. Officials needed to loudly publicize "YES, HEPA but *ONLY* HEPA". (UV can work too but is trickier, not a DIY project).

          The school district of Philadelphia installed window fans in preparation for students returning, and in some sort of negotiation with the teachers union the teachers demanded the district REMOVE the fans. Most students are not back but those that are don’t have fresh air.

          We bought one based on your advice and ran it when we had a babysitter came in. I also offered to buy extras for my kids classrooms but the school already had two for each room.

          My son (HVAC engineering sales) told me a few months ago that there was a worldwide supply shortage of MERV-13, but that may have been on the commercial side, not the DIY HEPA side.

          Irritating “well, actually”: at least among major outlets (home stores and Amazon), the California wildfires caused an interruption in many filters and models across the board.

          They weren’t out of stock, but the prices did go up during the course of the pandemic, as knowledge about airborne transmission spread. I bought 3 last fall, based on your writing, last most expensive.
