Prevention of cellulitis starts with good hygiene. Any breaks in the skin, such as cuts, bites, or scratches, should be cleaned with soap and water before applying a bandage. The area should be kept clean until the skin has healed over.
People with diabetes need to be careful with wounds to their feet or legs. Diabetes causes nerve damage, known as neuropathy, which can result in a lack of feeling in the legs and feet. Because people with diabetes may not be aware of a foot injury, they should inspect their feet daily for any cuts or abnormal areas. Diabetes also causes poor circulation, which means wounds do not heal well. As a result, cellulitis is more difficult to treat in people with diabetes.
If cellulitis is not treated, it can get worse. Some cases can develop into deeper, more serious infections of the tissue under the skin. This can lead to serious effects, including loss of a limb and even death. Many cases of foot and leg amputation in people with diabetes start out as cellulitis.
Cellulitis is not contagious and poses no risk to others.
