This document describes impetigo, a common skin infection caused by Staphylococcus aureus that usually affects children. It presents as small, painful pustules that may rupture and form yellow crusts. Treatment involves incision and drainage of abscesses, along with topical or systemic antibiotics like mupirocin, fusidic acid, cloxacillin, or amoxicillin depending on the severity of symptoms. Complications can arise if large areas of skin are affected or secondary infections occur.
