Erysipelas is a skin infection typically caused by group A beta-hemolytic streptococci, although other streptococcal groups are occasionally causative agents. Infection involves the dermis and lymphatics and is a more superficial subcutaneous infection of the skin than cellulitis. Erysipelas is characterized by intense erythema, induration, and a sharply demarcated border, which differentiates it from other skin infections.
Skin is the primary organ system affected.
Slight female predominance is observed. Erysipelas is a febrile illness with dermatological findings, characterized by an abrupt onset of illness with initial fever and chills followed by a painful rash occurring 1-2 days later. Muscle and joint pain may accompany illness. Nausea may be present. Headache and other systemic manifestations of an infectious process may occur.
