Impetigo is a cutaneous infection usually caused by either Staphylococcus aureus or Streptococcus pyogenes or both.


Clinically, one sees red, crusted areas, often of the face, but nearly any location may be affected. Children commonly develop impetigo about the nose and mouth. Honey-colored crust, pustules or bulla may be seen. Bullous impetigo is usually caused by staph.
