Can aids infected blood enter a dry healing cut, from accidental contact?

Same As Any. It would be the same for any cut on any part of the body. The risk increases with the amount of blood and how deep the blood is exposed into the wound. On average, the risk of HIV being transmitted to a person from exposure of blood from an HIV positive person to an open wound or cut is estimated at 0.03%. As the wound heals, the risk would be lower.
