I wrote about ventilation last July and to this day, I get contacted by desperate people who work in places that disinfect at length but don't have extensive ventilation mitigations, and consider six feet to as be-all-end-all. When they object, they're told that's the guidelines.

YES YES AND YES. Even in hospitals—which have aggressive ventilation & air is exchanged often and can mandate masks for everyone—we see the occasional outbreak because of the lunch room. Masks indoors at all times if around people *especially* if talking.https://twitter.com/Daniel22223333/status/1355941760195829760 …

𝔻𝕒𝕟𝕚𝕖𝕝, 𝔼𝕤𝕢. @Daniel22223333Replying to @zeynepSo for those of us who work in office buildings, wear masks at all times, to the extent practicable, while inside? That means no eating at desks (and since no indoor dining, so outdoor eating only); masks during zoom meetings; etc. That hard, but doable, if that's what's needed.15 replies 240 retweets 861 likesShow this thread -
Every time I make a peep on this topic (since the summer), I get inundated with these stories. People who haven't been told to keep masks on at all times indoors (even if distanced). People who know the importance of ventilation and aren't allowed to do anything about it. Tragic.pic.twitter.com/LCS7WJ1mka

This is the reality in many places. I'm hoping the new administration will quickly play catch-up with the messaging. It's finally mostly there in the guidelines, but needs messaging push. WHO needs a lot of catch-up as well. Fine print isn't enough.https://twitter.com/nacnudnosilla/status/1355944915763605504 …

This sucks, but at least they mention open windows. My inbox and DMs are full of people—and have been for months—who are not *allowed* to do any mitigation for airborne spread at work even when it's easy and available because "it's not in the guidelines."https://twitter.com/Riastradh_/status/1355989688956366848 …

Taylor Campbell @Riastradh_Replying to @zeynepMA guidance on indoor dining, Jan 25, 2021: focus on ≥6ft, ≤90min, plexiglass, surface disinfection.

We need to give people the right *intuition* on how this pathogen transmits—including its airborne spread—along with the rules. The cut-offs (6 feet etc.) aren't binary and the mitigations stack up. Once people understand the underlying logic, they can make better decisions.

In any workplace, disinfecting high-touch surfaces—especially non-porous ones like stainless steel—is sensible. Doesn't have to be excessive. Handwashing is *always* sensible. Washing hands after taking in groceries is sensible. Fomites are not ruled out.https://twitter.com/cativavante/status/1356258229748199429 …

One more article. Please note that the 6 feet/15 minute rule was *never* good advice because the rule didn't make sense for the public. It would have been better to properly *explain* the mechanisms of airborne transmission so people could use judgement. https://www.theglobeandmail.com/canada/article-covid-19-variant-in-barrie-outbreak-upends-conventional-wisdom-of/?utm_medium=Referrer:+Social+Network+/+Media&utm_campaign=Shared+Web+Article+Links …pic.twitter.com/bOcmiA8bob

Replying to @zeynep
history seems to indicate that explaining things to people with the hope that they use judgment is not the best idea. People respond better to short and concise messages, or even better, they respond to incentives.

Actually, last year is great proof on why you are wrong on this. Places that explained the mechanism and where people could use judgement are doing way better than us, where we gave rules and did not explain correctly.

I understand, but not sure that this correlation is necessarily about communication techniques, I think it is an important component, but only one of many. It certainly does not explain differences within the US, e.g. Norther California vs. South Florida
