The neat part is the update is because right after the article went live, CDC also updated its guidance. https://www.nytimes.com/2021/05/07/opinion/coronavirus-airborne-transmission.html …pic.twitter.com/EkgEGSmLme

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. 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 …
Yep. Overdispersed things can't be studied with methods not suitable for them. Example: information provided by non-events is asymmetric compared to info from events. Cluster-randomized trials—say for source control—can't easily get statistical power. Etc.https://twitter.com/DrPieterPeach/status/1391741852852756486 …
Let me highlight that excellent work has been happening all year, as well. Resistance to relevant expertise was a problem, but many key papers from this year are co-authored by people across disciplines. One interesting interdisciplinary panel today.https://twitter.com/VirusesImmunity/status/1391751814840717316 …
Excellent, rapid progress from the CDC, clarifying the tables that came with the aerosol update.https://twitter.com/linseymarr/status/1391863551132897285 …
I recently went through the same chasing down of known outdoor case percentage. Same conclusion. As @mugecevik explains, "less than 10%" is misleading. Reported numbers of confirmed cases are around 0.1% so way lower than 10% even assuming undercounting. https://www.nytimes.com/2021/05/11/briefing/outdoor-covid-transmission-cdc-number.html …pic.twitter.com/1Zr5Iuqj54
Seeing so many wondering if confirmed outdoor transmission can really be that low, compared with indoors. Yes. This confusion is another loss of being so late to acknowledge the key role of aerosols: the epidemiological record shows exactly what acknowledging aerosols predicts.
Yep, the problem with gyms — enclosed spaces where people engage in activities that we know greatly increase aerosol production — is that we aren't sufficiently good at spraying the weights with disinfectants. (ht @slowphotograph2)https://twitter.com/thehill/status/1392909521819996165 …
This is why the whole lack of clear communication and understanding around aerosol transmission—and the ensuing dominant visualization of COVID-19 mitigation as disinfecting, and its breach as people outdoors/beaches—matters. It makes things worse. https://twitter.com/dankrutka/status/1392913606522646538 …
The key takeaway is like everything "your on your own" these organizations exist to protect the status quo first and public health comes second. I get it that everything in life involves a tradeoffs but instead of rationally explaining the tradeoffs they chose to lie.
