HIV or Just Crazy

Hello, the other day I was driving and saw a homeless guy with a sign.  I drove on by and felt that I should stop and help the fellow out.  I turned around, went back, and folded up a five dollar bill and gave it to him.  He didn't see appreciative and just said "thanks".  He seemed for a lack of better description, homeless. He was sweaty and just looked sick. I remember thinking his hand was wet when he took the money.  I am a bit of a germaphob but anyhow, just kept driving afterwards.  I went home and washed my hands thoroughly.  I went on to talk with my wife about this event.  I was out getting some wine to enjoy that evening with my wife.  After discussing this with her for a little while, I opened the bottle of wine and poured a glass for the both of us.  I then started to drink from the glass and noticed that my finger was cut, on the first knuckle on the inside top of the finger.  I was the same hand that I used to give this guy the money.  I freaked out and said, did this guy cut me?  My wife thinks I am crazy, but I couldn't remember getting cut by opening the wine either.  So, then, a couple days later, I end up dizzy, with stomach pain and almost diarrhea.  I feel tired of course and a little achy, but nothing major that is stopping me from life.  The cut itself looks to be like a thin cut that you would get from a razor or a piece of metal.  Could be really anything.  So, in the end, is it possible this guy cut me when handing him the money?  Now that I am writing this, it all sounds crazy like my wife say... but I hate this feeling of worry and hope that you will have a professional opinion of what I should do and if it is even possible for him to do this without me knowing.  And, I didn't notice any blood on the finger when I washed my hands... but i wasn't really looking either.  thank you for any support you may provide.
