I want to add something. Recognizing SARS-CoV-2 as *predominantly* airborne isn’t an obstacle. It helps identify effective mitigations& chokepoints—like Japan did, for example. Airborne doesn’t mean it necessarily spreads like measles—a common error. TB is airborne but lower R0.

We briefly address this (word limit!
) but it's not correct to assume that airborne transmission necessitates either a high R0 like measles or even a uniform transmission pattern. Tuberculosis is airborne but has lowish R0—but likely also overdispersion!https://twitter.com/bobby_dread/status/1383787373134184450 …

Another good addition for people following this topic is Dr.
@linseymarr, a true pioneer in this field (her latest in@bmj_latest, also out this week(!), was titled "Covid-19 has redefined airborne transmission").https://twitter.com/linseymarr/status/1382842521286549508 …Show this thread -
And just putting this thread here so people can get some context of how difficult it has been, for so long, to make progress.https://twitter.com/linseymarr/status/1383066390136041477 …

Feels like an inflection point. Do read what the article linked by Dr. Karan argues: that short-range (close contact) transmission of respiratory infections is also PRIMARILY aerosols—goes against decades of claims of aerosols only/mostly being long-range. https://twitter.com/AbraarKaran/status/1384240928873844742 …pic.twitter.com/xvf2bQeES8

I still wipe down all my groceries regardless.

I wish we had animal studies to clarify this: e.g. expose ferrets to: 1)fomites in well ventilated/filtered air cage vs. 2)clean surfaces with unfiltered air exhaled from infected animals...I predict this would confirm aerosol but maybe a very small risk from fomites as well.

In retrospect, handling the gas pump, and then eating, was never the best idea…

Or riding the bus/subway and not washing hands afterwards. Blechhh! I think the old "wash your hands before you eat" is generally a good idea.

I'd wipe down high-touch surfaces pandemic or no pandemic...
