So I was in my martial arts class tonight and the new guy bled on me. Not much a few dabs of blood on my forearm from a scratch on his hand. I have a few old cat scratches and stuff around it, as in 48-72 hours old scratches around were his blood was. On top of that he may have got a few dabs on the forearm of another training partner. Later on this other training partner brushed his forearm across my mouth on accident. Should I be worried about HIV exposure this way? I don't know this guy though he seems to be a very nice guy, he comes in with his SO/wife to work out and I hate to think that of them but I am really worried about this.
In our training there is a lot of hard contact to our arms so I am afriad I could have been exposed through a small abrasion or one of my older scratches or when the other training partner brushed his forearm across my mouth.
