This isn't a jargon fight. The crucial problem is the *mechanism* needs explaining in order to arrive at the right mitigations and for those to make sense. "It occurs mostly at close contact" doesn't get us there, especially without explaining the correct underlying mechanism.

Frankly, I wouldn't have cared which word stuck as long as the underlying transmission mechanism, and its implications, was made clear. This has not happened. We can see it around the world. FWIW, the WHO and the CDC call Tuberculosis airborne. It's their standard term for this.

Here's the Lancet paper on this (disclosure: I'm a co-author). It's true, there are a lot of misunderstandings about what "airborne" implies. We should correct all that, but have to start from the right place. It shouldn't be this hard to move forward.https://twitter.com/EricTopol/status/1382825519171833859 …

I hear this from around the world. This is true for Turkey as well, amidst a deadly surge but still has complete curfew (NO OUTDOORS!) for weekends, and barely a mention of what airborne transmission means. This is why it's not some jargon quibble.https://twitter.com/sandeeprtweets/status/1385248772255535107 …

That's tragic. Also, there are misconceptions about aerosols that generate undue fear—it doesn't mean it's necessarily like measles, that we should always wear N95s etc. The way to reduce undue fear *and* make progress is for health authorities to step up.https://twitter.com/avtansh/status/1385260846570426369 …

People won't know this, and think they're "reopening safely" because they wash their hands and adhere to distancing. And then get surprised they wind up into a cluster, all while thinking they're just outliers

A policy like: 1. Mandate to keep indoor air under 600 ppm CO2 or 6 ACH HEPA 2. Optional masks outside 6 feet 3. Masks required if within 6 feet 4. Emphasis on mask fit. Is simple and is better aligned with observed transmission dynamics.
-
Optional masks indoors is a horrible policy. Needs to be mandatory even at long distance for source control AND to protect wearer.

Agree But cognitive load is very high for layman . Better to have blanket directions. Bcoz outdoors is great for solitary excercise but close contact gatherings outdoors without masks is super spreader event .
-
Outdoor contact is not the big problem. The issue is that some type of outdoor gatherings inevitably generate indoor contact. E.g. beach or concert toilets are some of the most unsanitary and badly ventilated places attended by large groups of people.
