That is a common misconception, though. It CAN BE spread through the air.
What people don't realize, is when a person is sick enough and has norovirus, you can actually breath it in and get sick, because tiny particles (yes, human waste particles if you want to get specific) actually go into the environment.
Also, norovirus is EXTREMELY resilent. No, washing your hands isn't a guaranteed prevention technique. Nothing is.
Anyway, many people come to this website for information, and I think spreading false information, regardless of the motives, does more harm than good.
While it is certainly a novel idea that vaping somehow increases your chances of not getting sick, there is not a shred of evidence to back up that claim.
I'm not trying to be a party pooper, nor say it is impossible. I just don't want people to get the wrong idea from reading this thread.
