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

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 …

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
