Cellulitis is an infection of the skin and underlying tissue caused by streptococcal, staphylococcal, and other bacteria. This infection is serious and should receive immediate medical attention. Cellulitis is usually worse for those who have reduced resistance to infection because of disorders such as diabetes or a deficiency of the immune system. Cellulitis most frequently occurs on the face, arms, or legs, but it can occur anywhere. Bacteria enters the body through a cut or sore.
Enzymes produced by the bacteria destroy skin cells.
The infection spreads over the area for about 2 days. The lymph glands may become swollen and tender. You may have a fever and a feeling of general discomfort. If left untreated, the amount of bacteria produced can reach poisonous levels. Orbital cellulitis, a particularly dangerous infection, usually develops when bacteria enter the soft tissue around the eye socket from the sinuses or a boil near the eye.
