Causes of Erysipelas
Erysipelas is caused by bacteria penetrating the outer barrier of your skin. The bacteria that most commonly cause erysipelas are known as streptococci, and they normally live on your skin and other body surfaces without causing harm. They can, however, enter your skin through a cut or a sore. Conditions that cause breaks in the skin, such as athlete’s foot and eczema, can sometimes lead to erysipelas.
In addition to openings in the skin, anything that prevents blood or fluid draining from an area of your body can make erysipelas more likely to occur.
In cases where your face is affected, the bacteria may have spread there from your nasal passages following an infection in your nose and throat.
