Sorry - can't sleep because I've been exposed to SV and I'm scared if I sleep I will wake up feeling s*. So I'm ranting around here instead!
If you are ever worried then just bear these things that have happened to me (and I did not v*") in mind:
I once cleaned the toilet and a bit of the water splashed me on my mouth. I was fine.
My boyfriend (now husband) years ago thought it was funny to lick my face after he had v*d. I went into a blind rage and swear if there were any instruments around I would have used them on him! I was fine.
I ate a sandwich that after about three quarters of it, I noticed it had a lot of mould on it! I was fine.
I ate some ham one lunchtime. Later that day I went to get some more but it was gone. I asked my mum where the ham had gone and she said she threw it out because it had gone off! I freaked as I had eaten some at lunch. I was fine.
The worst time of my life ever was when my husband and both my kids all had an sv at the same time. I was seriously losing my mind and I'm sure now I had a mini breakdown of some sort. But, as with us emets, my hygiene and other habits helped me and.....I was fine.
I once went to my friend's house for dinner. She had cooked and when we were eating, she told me she had v*d twice that morning and didn't think she could eat any more of the food. I was furious she hadn't told me. I was with her for over an hour before we ate. Then I was almost done eating when she told me. I was terrified. I was fine.
Hope this helps. It goes to show that you will not always get ill if you are in contact with anything horrid. I try to think of these times when I am worried, like now. So if it helps you some, then great.
