Picture of Impetigo
Impetigo. A bacterial skin infection caused by the staphylococcus or, more rarely, streptococcus bacteria. The first sign of impetigo is a patch of red, itchy skin. Pustules develop on this area, soon forming crusty, yellow-brown sores that can spread to cover entire areas of the face, arms, and other body parts. Most patients are children. Treatment is by antibiotics.
