Erysipelas is a type of skin infection. It affects the outermost layer of the skin and the local lymph nodes.
Erysipelas is usually caused by group A streptococcus bacteria. The condition may affect both children and adults.
Some conditions that can lead to erysipelas are:

- Problems with drainage through the veins or lymph system

The infection occurs on the legs or arms most of the time. It may also occur on the face and trunk.
Symptoms of erysipelas may include:

Antibiotics are used to get rid of the infection. If the infection is severe, antibiotics may need to be given through an intravenous (IV) line.
