One day ago, I got small cuts with bleeding on my thumb while I removed fingernail from it.
Last night, I went Karaoke with several friends ( I knew some of them have more than one sexual partners, I did not know their status of HIV). I shook hands with them. At that time, my cuts looks like no bleeding but with little tissue fluid outflow and the cuts are redness.
Afterwards, I believe I contact several people's hands or body. I am not sure if their hands has cuts with bleeding or not.
If I assume one of them has HIV positive and has cuts on hand with bleeding, here as my questions:
1. Although my cuts are not bleeding, but it is still blowing out tissue fluid. Do I have risk to get HIV Infection by shaking hands with one (his hand is bleeding and his blood contact my cuts)?
2. If I am both bleeding and blowing out tissue fluid, do I have risk to get HIV Infection by shaking hands with one (his hand is bleeding and his blood contact my cuts)?
I know my question looks silly, but I still want to get your comments and make my peace of mind.
