What causes cellulitis?
Cellulitis is caused by a bacterial infection, usually when the skin breaks, and is exposed to bacteria that live on the surface of the skin. Any injury to the skin can potentially help expose the person to a cellulitis infection. Remember that the skin injury may not necessarily be visible to the naked eye. Many small injuries are too small for the eye, but provide bacteria plenty of space to infiltrate the skin's surface.
