Erysipelas is an infection of the upper layers of the skin.
Erysipelas is caused by specific bacteria. In most cases, it is Group A streptococci. These bacteria normally live on the skin or come from sources outside of the body. It can enter the skin through a cut or injury to the skin. Once inside the skin, the bacteria can grow and spreads into the surrounding skin layers.
Erysipelas can occur on skin anywhere, but most often affects the face, arms, or legs.
Symptoms may include:
Skin that is warm, red, firm, and swollen
Pain or tenderness
Swollen glands or lymph nodes
Fever or chills
You will be asked about your symptoms and medical history. A physical exam will be done. The doctor can diagnose erysipelas based on the appearance of the skin.
Further testing may be done if the infection does not respond to treatment as expected, for certain infection source, or if there is a compromised immune system. Information about the infectious agent and the body’s response can be found through:
Cultures of blisters
—a sample of the affected area is removed and cultured or examined under a microscope
Antibiotics are used to treat bacterial infection. The medication may be delivered by IV, or by pills or liquids by mouth.
To help reduce your chance of erysipelas:
Your doctor may give you preventive low-dose antibiotics if you have had many infections.
Keep your skin clean.
Moisturize dry skin with lotion.
Treat fungal skin infections if present
Avoid injury to the skin:
Wear protective gear in sports.
Wear long pants and long-sleeved shirts when hiking.
Wear sandals when at the beach, rather than going barefoot.
Be careful around animals. Treat pets with respect to avoid bites.
If a small cut, bite, or other injury occurs, carefully treat the wound:
Clean cuts or scrapes with soap and water.
Apply antibiotic ointment.
Cover wounds with a bandage or dressing.
Do not scratch wounds.
Call the doctor right away if the area becomes red or inflamed.
Seek prompt medical care for larger wounds or bites.
If your legs tend to swell, elevate them several times a day and wear support stockings.
Follow treatment plans for chronic health conditions.
