I would like to know what an open wound is defined as with regards to HIV transmission? Everywhere I read, open, actively bleeding. But this could also mean a paper cut, a shaving nick, a scratch etc. So are these the type of wounds you refer to when you say there is a risk of transmission? Or does the wound have to be very deep, profusely bleeding & requiring stitches? I'm only concerned because if I touch a door or any surface that has blood on it and I have a small freckle sized, but fresh cut on my hand (by fresh I mean a few hours old, but still slightly bleeding) then am I at risk?
