Hi alderick84,
Thank you so much for your answer. At that time, i didn't have any bleeding wound or scar on my hands, and i didn't know the one crashed with me was HIV positive or not. I just feel worry and went to the hospital and took the test. I afraid that when i was home, i just wash my hands by water without soap or stuff like that, and after that i scratched my eye by that hand, which, i think, would put me into to a risk. How about your idea ?
Do you know or suspect that the person that was with you is HIV positive? HIV is very fragile outside the body, only fresh, open and actively bleeding wounds a viable as entry points, not scratches o dry wounds.
According to CDC your test is almost conclusive and unlike to change, CDC recommends confirming that with any test 12 weeks after exposure.
But I think you weren't exposed to a risk in the first place.
