Cellulitis is a localized or diffused inflammation of the dermal or subcutaneous layers of the skin. Cellulitis occurs when bacteria enters the body, usually through a cut or crack. Symptoms include redness of the area, hardened skin that is hot to the touch, local pain and sensitivity. There are a few systemic symptoms which can indicate cellulitis – a high fever, and headaches.


Commonly affected areas:

  • The limbs – common for children under age 3
  • The face – common for children under age 3

Bacteria causing Cellulitis
There are a few common types of bacteria which cause cellulitis – staphylococcus and group A streptococcus. Both of these bacteria are found on the outer skin surface but will not cause an infection while on the outer skin surface. The bacteria enter the deeper layers of the skin through an insect bite or a cut. Less common are group B streptococcus (GBS), pneumococcal (common under age 3 months) and pseudomonas. To identify the bacteria, the treating physician will take a culture from the infected area in addition to conducting a blood test.

Treatment for Cellulitis
Treatment for cellulitis is generally antibiotics. They are administered via IV. Later on, the doctor will give you a prescription for oral antibiotics. Surgical intervention is very rare and only occurs in order to drain excess pus or remove the foreign body causing cellulitis.

Periorbital Cellulitis
Periorbital cellulitis is a bacterial infection of the outer portions of the eyelids. Symptoms include swelling of the eyelid tissue, redness, pain, itchiness, and edema. Sometimes, the eye will be completely shut. Periorbital cellulitis is caused by streptococcus, staphylococcus, and haemophilus influenza. Similarly to other infections, the local periorbital cellulitis can spread throughout the body.

Treatment of Cellulitis
Doctors administer antibiotic treatment through an IV, and later on will prescribe oral antibiotics.
