Earlier I read that freezing doesn't usually kill the virus. I guess it can hang onto packaging within your freezer? Now, this. I'm glad there's so many scientific minds working on learning about CV-19. Just the words
aerosol particles sends my mind racing. Does it just rides on particles like a surfer? These may sound like stupid questions, but could it attach to household or dusting sprays? How about non-stick cooking sprays?

"A growing number of studies, including one published this week in the journal Nature, have found evidence that the coronavirus can remain suspended in the air in aerosol particles."
Basically, it rides INSIDE the water packet, until that aerosol is deep in your lungs, where the particle opens up, you breathe, and voilà! You're now infected.
There's a ton of really interesting research on this part of viral transmission (it's not just CoVid of course). When humidity goes up, the newly sneezed or coughed out packets from someone else is just one of millions of bits of wetness in the air (nicely wrapped up in their mucous, which provides a temporary boost to the life of the virus outside its host). So, while you still breathe it in, as a percentage of the water molecules you're breathing in, it's a low percentage. This seems to matter with this virus.
In dry weather, there's virtually no moisture in the area, so the virion-laden packets are the only moisture breathed into already dry lungs, which crave the humidity and the percentage of infected packets is very high (if you're in a room already contaminated or nearby a transmitter).
Apparently, though, once the virus does attach itself to water molecules in a humid environment, those molecules by their nature are pulled by gravity down to the ground (which is why there's sometimes still dew even in dry environments). Once the virus is on the ground, unless you too are crawling around or putting your hands on the ground, you're unlikely to get it. In several studies, 100% of hospital floor samples tested positive for CV-19 in CoVid wards, whereas bed railings had considerably less (still a lot, but nothing like the floor). The more humid the place was, the faster the virus ended up on the floor.
So shoe protocol is important. I figure I don't have CV in my house. I am not the least bit afraid of cooking spray or the like. Where would the CV come from in the first place? It's so rapidly killed by hot sun (and we have that here in SoCal), I rely on leaving packages in our sunroom for 2-3 hours up to 2-3 days, depending on whether we really need to use it.
But I'm a bit of a weirdo in that I'm willing to risk 1-2 virion getting into my respiratory system; what I'm trying to avoid is 30,000 per sneeze by the guy behind me on the plane, who is sneezing 12-20 times an hour.
