Cellulitis is an acute or chronic inflammation of the subcutaneous connective tissue that is commonly caused by Staphylococcus aureus or Streptococcus pyogenes bacteria. Erysipelas is a specific bacterial skin infection that involves the dermis and subcutaneous layers. Both conditions are more common in children under 3 years old and in people with malnutrition, alcoholism, or other chronic diseases. Symptoms include localized redness, swelling, pain, and warmth of the affected area, usually on the face or lower extremities. Treatment involves local compression, antibiotics like penicillin or cephalosporin, and management of any predisposing conditions.
