Exactly. Aerosols are like short-range mist—the closer you are to the person emitting it, the more exposure *but* under the right conditions (poorly ventilated indoors space), the mist can accumulate and even be pushed around by air currents beyond 6 feet. https://twitter.com/dylanhmorris/status/1289612851762667521 …

Peter StaleyVerified account @peterstaleyMy morning text to#TonyFauci, which led to a call during his powerwalk. He said he'd share it w/@CDCDirector (hopefully when Redfield comes up for air from licking you-know-whose you-know-what). An amazing article,@zeynep! A must-read for everyone: https://www.theatlantic.com/health/archive/2020/07/why-arent-we-talking-more-about-airborne-transmission/614737/ … pic.twitter.com/97iZYu1P3611 replies 40 retweets 420 likesShow this thread -
What it's like to be a woman writing about tech/science/society. Two things happened the same day, and one of them is random dude telling me I "clearly have no clue" about airborne spread, just after I wrote a ~5K article about it. No track record is ever good enough for women.

Because of my piece on ventilation, I keep getting asked for practical advice. CDC and health authorities should update guidelines. But for individuals? I'd say avoid Japan's 3Cs: closed spaces, crowded places, close-range conversations. And wear masks. https://www.theatlantic.com/health/archive/2020/07/why-arent-we-talking-more-about-airborne-transmission/614737/ …pic.twitter.com/w9lnPVUhDB

Pandemic theater. Broncos players are coming out of an *indoors* locker room, to pant at each other at close range, but not before being sprayed by, uh, mumbo-jumbo nano-crystalline disinfectants!. (Do more! Activate the holosensors! Use positronic beams too!)

I mean if we’re going to do pandemic theater, at least let’s do it right, with some elegance amd history. My grandmother would’ve put an evil eye charm on all of them.

Write an article about aerosols, get a LinkedIn inbox that feels like who's who of HVAC/IAQ companies.
No I can't endorse products.
But my own AC is on the fritz? (And my landlord is trying to evict me, so not going corrupt and helping fix his AC for free at the same time!)3 replies 6 retweets 97 likesShow this thread -
YES! Dr. Fauci acknowledges some aerosolization. Says indoor/outdoor different, indoors "much greater risk than outside.” Emphasizes "mask-wearing indoors." Acknowledges ~5-10 μm can float, says they likely got that wrong.
Now, hopefully new guidelines! https://www.cnbc.com/2020/08/03/fauci-says-theres-a-degree-the-coronavirus-is-spreading-through-air-particles.html …pic.twitter.com/flPn9T4V8a

Thrilled to see the message about the importance of ventilation *finally* breaking through to the broader public (at least, I hope so!). (Sane policies for/media coverage of the safer activities outdoors, maybe, too, one can hope?)https://twitter.com/misguidedsoul7/status/1291069337600774144 …zeynep tufekci added,

Replying to @zeynep
I wish there were guidance on whether high quality HEPA air purifiers that change the air several times an hour are useful indoors, and when or whether that's better than opening windows. (In winter, are we going to need to freeze, or will air purifiers substitute?)

I’ll get back to you. The answer is yes, indoors, for Hepa filters—but no gimmicks. There are ways to calculate appropriate size etc. Later.

(And yes, we should have a official guidance rather than doing it ad hoc via the scientists.)
