Apparently it gets properly airborn mostly in enclosed space where people talk/sing/shout. Otherwise bigger dropplets fall to the ground and smaller are dispersed. This guy explain it wellhttps://www.youtube.com/watch?time_continue=689&v=gAk7aX5hksU …

BAD PHYSICS !! Mists float. That's anything under 15 microns. How long a particle floats depends on initial size, temperature, relative humidity. 12 micron droplet = 100:1 length vs. this CV = 10,000:1 cross-section - 1,000,000:1 volume The 120 nanometer CV hitch hikes easy !pic.twitter.com/fU1guR6Tf5

Yes all the clusters I’ve read are wedding receptions, St Patrick’s day bar, buffet dining, choir, a school, and then longer exposure rest home or cruise ship. All indoors sharing air. This has to massively inform our post shelter in place world.

Also suggests some possible reasons why NYC is so bad: everyone uses the subway, tiny apartments with shared elevators.

NYC subway though doesn’t seem right - the distribution of cases seems wrong vs reality

Could be that air pockets and surfaces spread evenly BUT we beat surfaces way before air pockets. Many I know were hand sanitizing and not touching their faces long before donning a mask.

And... Boxing matches, loud discos. Anywhere with alcohol as that means spit and lots of shouting. It hardly seems to transmit by surface contact. German scientists couldn't even find traces on obvious contact areas like door knobs of those infected.

YES !!! The Wuhan Hubei data was modeled to an inch of its life. R=factor like rubella / measles. 5.7 for symptomatic. 3.1 for asymptomatic. Then if not hit w/ INF-A-2B it can kill like plague.pic.twitter.com/3EJJr0lwxN
