Erysipelas is an infection of the upper layers of the skin. It can lead to other problems if left untreated.
Erysipelas is caused by germs called bacteria. These germs live on the skin or come from other sources. They can enter the skin through a cut or injury to the skin. Once in the skin, the germs can grow and spread to the surrounding skin layers.
Erysipelas is more common in infants, young children, and older adults. Other things that raise the risk are:
