So the assumption that’s driven a lot of the models regarding the spread of Covid so far has involved the idea that transmission might be “Aerosol” – that the virus might hang suspended in the air for a period of time, until it latches onto a passing human, who might inadvertently ingest it into vulnerable tissue via the nose or mouth.
But what if it’s transmitted most readily by something less persistent, and more predicatable?
Amazing study, supporting droplet (rather than aerosol) as key means of transmission. One asymptomatic person infected 10 (out of 91) at restaurant—but *only* if they were in direct line of air pushed by the A/C. (Aerosol would have infected others, too). https://t.co/j8VXjnWtlN pic.twitter.com/w8yNENCT6M— zeynep tufekci (@zeynep) April 18, 2020
Note to “Progressive” readers Those are actual scientists.
My hunch – since this theory impugns population density and the “Blue” urban lifestyle to which so much of our chattering class subscribes, it’ll be downplayed.
