Dear doctor:
The night before I pulled out my agnail of Fingernail(the agnail growing on the hand--- forefinger), a little bleeding, A few moments later the wound(forefinger) stopped bleeding, Second day i have a football game in the afternoon, and i shake hands with other players and the referee, I remember they didn't touched my wound. Intense competition of the game, I do not know Whether the wound has been touched? for fear of wounds. At half-time, bought a Band-aid, after washing hands, with clean paper around the fingers(Fingernail wound) wrapped around a circle, then paste the Band-aid, finally, the end of the game, i found on the paper, there are two small traces of blood, very worried about whether the wound still is an open wound, Can it prevent virus?( HIV), worry that the wound was touched by someone else.
I'm too scared and now cannot be confirmed that the blood mark(the two small traces of blood) is mine or someone else, So I am very worried!
1.Please help me analysis, I wii be infected with HIV? Traces of blood is mine or someone else's?
2.The wound(need to use external pressure will have blood) is also an open wound? Can it prevent virus( HIV)?
Thank you very much!
