well it is for a short period of time after an infected person coughs or sneezes... ;-)

That's not airborne. When someone sneezes, spraying an area with their snot, and the virus is in that snot - of course you'll be infected if you get any of it on you.

Every contagion meets that "qualification." In reality though, it's transferring person-to-person by physical contact. That is, bodily fluids.

Nope. I'm afraid you guys have been had.
