Skin infection - bacterialDefinition Return to top
Cellulitis is an acute inflammation of the connective tissue of the skin, caused by infection with staphylococcus, streptococcus or other bacteria (see also cellulitis - streptococcal).Causes, incidence, and risk factors Return to top
The skin normally has many types of bacteria living on it, but intact skin is an effective barrier that keeps these bacteria from entering and growing within the body. When there is a break in the skin, however, bacteria can enter the body and grow there, causing infection and inflammation. The skin tissues in the infected area become red, hot, irritated and painful.
Cellulitis is most common on the face and lower legs, although skin on other areas of the body may sometimes be involved.
Risk factors for cellulitis include:

Signs and tests Return to top
During a physical examination, the doctor may find localized swelling. Occasionally, swollen glands (lymph nodes) can be detected near the cellulitis.
Tests that may be used:
Treatment Return to top
Cellulitis treatment may require hospitalization if it is severe enough to warrant intravenous antibiotics and close observation. At other times, treatment with oral antibiotics and close outpatient follow-up is enough. Treatment is focused on control of the infection and prevention of complications.Expectations (prognosis) Return to top
Cure is possible with 7 to 10 days of treatment. Cellulitis may be more severe in people with chronic diseases and people who are susceptible to infection (immunosuppressed).Complications Return to top
Calling your health care provider Return to top
Call your health care provider if symptoms indicate that cellulitis may be present.Prevention Return to top
Avoid skin damage by wearing appropriate protective equipment when participating in work or sports. Also, clean any breaks in the skin carefully and watch for redness, pain, drainage, or other signs of infection.
Finally, maintain good general health and control chronic medical conditions. A body that is healthy can more easily fight bacteria before they multiply and cause infection, while a body that is run down has less protection against infection.
