Erysipelas is a type of skin infection (cellulitis).
Erysipelas is usually caused by group A Streptococcus bacteria. The condition may affect both children and adults.
Risk factors include:
In the past, the face was the most common site of infection. Now it accounts for only about 20% of cases. The legs are affected in up to 80% of cases.
Erysipelas is diagnosed based on how the skin looks. A biopsy of the skin is usually not needed.
Antibiotics such as penicillin are used to eliminate the infection. In severe cases, antibiotics may need to be given through an IV (intravenous line).
Those who have repeated episodes of erysipelas may need long-term antibiotics.
With treatment, the outcome is good. It may take a few weeks for the skin to return to normal. Peeling is common.
In some patients, the bacteria may travel to the blood. This results in a condition called bacteremia. The infection may spread to the heart valves, joints, and bones.
Other complications include:
Call your health care provider if you have a skin sore (lesion) that looks like erysipelas.
Keep your skin healthy by avoiding dry skin and preventing cuts and scrapes. This may reduce the risk for erysipelas.
