In brief: Not the "infections"

All bacteria are contagious, meaning that one person can smear some of his bacteria onto another's skin or other body part.
The bacteria can then die, multiply on the surface (colonize the surface), or damage the person's cells and body parts (start an infection). No infection occurs in many cases, meaning the "infection" did not spread to the person even though the "bacteria" did spread to him.
