What is Cellulitis?

Cellulitis is a common bacterial skin infection. It typically affects the skin on the lower legs, but can occur in the face, arms, and other areas. Cellulitis occurs when there is a crack or break in the skin that allows bacteria to enter.  Unlike other skin conditions, this condition affects the deeper layers of the skin (the dermis and subcutaneous tissue). Since the deeper layers are the ones affected, cellulitis is not contagious.

Signs and Symptoms

Signs and symptoms of cellulitis often begin as a small area that is tender, red, and swollen, that spreads to the surrounding skin. There are many common signs and symptoms. If you experience any of the following more serious symptoms you should seek medical attention immediately.

Causes & Risk Factors

Cellulitis occurs when bacteria enters the skin through a crack or cut in the skin. The common types of bacteria that can cause cellulitis are Staphylococcus and Streptococcus. Cellulitis often starts as a cut, bug bite, or surgical wound.

Risk Factors

  • Injury.
  • Weakened immune system (HIV/AIDS, people receiving chemotherapy or immune suppressants).
  • Skin condition.
  • Chronic swelling (lymphedema).
  • History of cellulitis.
  • Obesity.


To help prevent this condition, follow theses precautions if you have a skin wound:

  1. Wash your wound daily with soap and water.
  2. Apply a protective cream or ointment (vaseline, polysporin, etc).
  3. Cover your would with a bandage and change bandages at least once a day.
  4. Watch for signs of infection such as redness, pain, and drainage.

People with diabetes and those with poor circulation should take extra precautions when dealing with skin wounds such as:

  1. Inspect your feet daily, looking for any signs of injury.
  2. Moisturize skin regular to prevent cracking or peeling. Do not apply moisturizer to an open sore.
  3. Trim fingernails and toenails carefully to prevent injury to surrounding skin.
  4. Protect your hands and feet by wearing proper footwear and gloves.
  5. Quickly treat superficial skin infections (Ex. athlete’s foot).

If your condition recurs or you notice signs of infection seek medical treatment.

Treatment of Cellulitis

When receiving treatment for cellulitis a culture for bacteria is often performed to insure the correct treatment is being administered. Treatment often includes oral or intravenous (IV) antibiotics. In more severe cases that include an abscess, surgical drainage is typically required. Once treatment is sought, symptoms typically resolve in 3-10 days after beginning antibiotics.
