Are bacterial infections contagious?

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.
Technically correct. While dr. Kwok's answer is exactly right, the practical answer is yes. Bacterial infections can be passed from one person to another, and are therefore contagious. It is possible, however, to come in contact with a bacterial infection and not catch it.
