Channeling Carl Bersgtrom: calling bullshit on droplets vs aerosols

@dan_diekema responded to my criticism, and I responded at the bottom of the thread. But reposting since it may be missed otherwise. https://twitter.com/dan_diekema/status/1300905640676687873
Thanks for the response, but I beg to differ.
- Video is in YouTube accessible to everyone
- Friend on Iowa telling me that it's being used by institutions to dismiss aerosol controls
- Interventions ARE different. Aerosols need more than droplets. See http://tinyurl.com/faqs-aerosol 
- And just a perfect example of the prevailing view that is making progress difficult
- E.g. my native Spain, "WHO and droplet country", lots of plans for schools, no mention of increasing ventilation whatsoever. The same in lots of places, also in Boulder till we pushed
- Sorry to have to take this approach, nothing personal, but we are in an emergency, and this stance is greatly slowing progress
- Pandemic is transmitted in community, need to communicate clearly to them, give the best tools to protect themselves
5/ Always some bad stuff being published in aerosol science (that has nothing to do with disease transmission). You won't find me ever criticizing it in a public forum like this. But we are in a global emergency, ppl are dying, and this stance is blocking progress
And for the record, I view the "continuum" argument as flawed. Yes, there is some transition in properties vs. size, but < 100 um can linger in the air and be inhaled, and don't have enough inertia to behave as droplets. > 300 um opposite in all counts. https://twitter.com/jljcolorado/status/1295526407401959426
So large droplet vs aerosol has a pretty clear separation, with a "no man's land" between 100 and 300 um. And that is extremely useful to understand the issue.

And once you understand that, you realize that droplets don't matter unless cough or sneeze. https://twitter.com/jljcolorado/status/1292890643233005568
So if it is aerosols, let's call them aerosols! Then we can use the extensive existing knowledge to protect against them smartly: https://tinyurl.com/FAQ-aerosols 

Which does apply to HCW. It just has little to do with the traditional "airborne like measles"
