While I understand the need of caution, airborne transmission seems to be a minor chance or fluke at best for SARS-CoV-2 if it's even proven to occur at all. Pertussis and measles, for instance, are true airborne diseases and the difference in rate of contagion is insane. They can double or triple the number of people infected literally every day if let loose in an non-immunized population.
Also, a small side curiosity. I've seen the case report of a man who contracted conjunctivitis from his girlfriend, ahem, passing gas to his face (you can imagine the sexual acts involved on your own). So, a warning on another airborne bacterial disease to you right there.
