I think it goes airborne when people die. It is their last breath.
I’m assuming that it goes airborne anytime body fluids become aerosolized as in explosive diarrhea, projectile vomiting, toilet flushing, intubations, coughing, sneezing, during nebulizer therapies. I am assuming that because that’s what the center for infectious disease says and because, as an ER nurse, I may have to deal with this crap and I don’t plan on listening to the dumbasses that have gotten everything wrong thus far. What somebody else chooses to do with their life is their business though.
