While helping someone on an outdoor electrical installation I was pricked with an electrical wire. I could see a couple of red dots on my finger, and a tiny bit of blood. Some 30 seconds to 1 minute before someone else had been pricked too and also had a visible red dot on his thumb (I learned of this after). It might have been the same strand of wire or not (electrical wires have multiple copper strands inside the plastic cover, which are the ones that can prick). Is there any chance to get HIV from that?
