Cellulitis:
A parent's guide for infants and babies

Cellulitis is a bacterial infection of the skin that can appear as a red, swollen area of skin that may feel warm to the touch. The most common bacteria causing cellulitis include Haemophilus, Staphylococcus, or Streptococcus. While the skin may appear to be intact, there are often very small cracks (fissures) in the skin through which the bacteria enter. The infant may also have a fever or seem fussy.

While the infection may be just on the top skin layer (superficial), it can also affect deeper tissues, involving the muscle, bone, and possibly blood. It is important to recognize cellulitis as early as possible so it can be treated with antibiotics. If left untreated, cellulitis may turn into a life-threatening condition.
