Isn't an aerosol pretty much by definition able to be carried all around by air currents rather than being just a briefly suspended droplet? I do agree though that the bathroom sink area seems like an important thing to test. I'd have thought it's of much more interest than the floor beside the toilet.

- thfuran 3y agoThere definitely will be a distribution of droplet sizes (plausibly not unimodal) depending on the mechanics of what's producing and dispersing the droplets. Broadly speaking, the smaller the droplet, the longer it stays in the air. I'm not sure precisely where the line is, but in the context of virology, 'droplet' and 'aerosol' are distinct. Droplets are large enough that they still fall mostly ballistically, albeit potentially a bit slowly for very small droplets. But once it's small enough that it doesn't really fall anymore, it's an aerosol. And they can remain suspended in the air for hours.
