It usually starts in an open area on the skin. Impetigo is a common skin infection in children. The child has suffered an insect bite or scratch. This area becomes easily infected with the Streptococcus bacteria (it is in the same family as a "strep throat" infection). The infected area develops a crusty scab with an intermittent yellow oozing. The rash usually itches and occasionally blisters will form. Once the child is infected, the itching causes the child to scratch and the impetigo spreads to normal skin around the infected area. It can spread to other areas of the body and even to other people through direct contact with the sores or from contact with the child's hands.

After scrubbing, pat dry and apply an antibacterial ointment such as Neosporin, Bacitracin, or Triple B.

Call your doctor if the impetigo infection is widespread or if the local treatment does not work within a few days. Oral antibiotics may be necessary.
