What are diaper rash symptoms and signs?

A diaper rash is a change in the skin enclosed by a child's diaper. Most commonly, the involved skin is red and may or may not have erosion of the superficial skin layers. Pustules or small blisters may be present. If the irritated skin is sensitive, diaper changing may be mildly uncomfortable to the child.

How do doctors diagnose the cause of a diaper rash?

Most diaper rashes are a result of skin irritants (urine and/or stool) inflaming immature, vulnerable skin. Such a rash is termed a contact skin irritant rash. Two types of infections may occur independently or be a complication of a contact diaper rash. Staph and strep bacterial skin infections may be associated with pustules or tiny blisters. A Candida yeast infection may also develop in the diaper region and around the anal area.
