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 …

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 …

Ironically I feel like much of the public grasped this months ago even though authorities stuck with it

If you were following the right people on Twitter, maybe? Media was busy beach shaming. Plus, in workplaces and schools—and around the world where WHO guidelines are basically are the rule—you couldn't get any resources to address ventilation because it wasn't in the guidelines.

But is addressing ventilation much easier said than done?

It may be challenging but denying the issue definitely didn’t help

My most striking example is airplanes were the issue *was* addressed—ventilation, frequent air exchange, HEPA, change of engine status during parking—but all the adverts I got from the airliners were about their.. extra disinfectants. Which I don't want to breathe in the cabin!

Yeah, like this one had not one word about cabin air exchange or filtering which, frankly, is excellent. I'm reading this yelling, silently, please tell us instead that cabin air is exchanged *completely* 20 times per hour, and plus is subjected to HEPA and/or MERV filtration!pic.twitter.com/Vxu5vhAXcz

I think they know that the average person will respond more strongly/positively to the word disinfectant. The idea of airborne spread and ventilation is a much more nebulous concept (although it shouldn’t be). Disinfectant is a much more tangible intervention for the customer

An interesting historical twist. 20th century public health long fought the miasma theories, for good reason—and I come from part of the world where "drafts" are still feared—but long interesting story later ended up resisting airborne (which is harder to prove, like for TB).
