If someone with HIV touched you in an open wound and they had blood on them somewhere that could cause you to get HIV

If the blood of someone infected gets mixed in with yours in an open wound, it could transmit the disease to you through the bloodstream.

Essentially you can get it by someone else’s blood going into yours through the cut.
