No, saying that she/you/we can catch a stomach virus from saliva is giving misinformation.

"I would rather say something [like above] that may or may not be able to happen and her be cautious with what she does and who she's around than everyone to say oh no you can't and then somehow she catch it!"

^That's doing more harm than good. I don't know how bad kristabelle's emetophobia is, but I'll bet dollars to doughnuts that your untruths are scaring the pants off of somebody. If I was the same fearful person today as I was half a decade ago, your reply would have made me stop kissing everyone - my husband, my kids, because 'It's in their saliva. What if they're incubating? I don't wanna get sick.'.

Additionally, I don't think that our focus should be on keeping others from getting a stomach virus. There are people here who may never vomit again a day in their life, but they're still afraid. Anxiety is our problem.
