Impetigo (im-puh-TIE-go) is a common and highly contagious skin infection that mainly affects infants and children. Impetigo usually appears as red sores on the face, especially around a child's nose and mouth, and on hands and feet. The sores burst and develop honey-colored crusts.
Treatment with antibiotics is generally recommended to help prevent the spread of impetigo to others. It's important to keep your child home from school or day care until he or she is no longer contagious — usually 24 hours after you begin antibiotic treatment.
