Diaper rash (diaper dermatitis) is a bright red rash caused by irritation from prolonged skin contact with urine or stool anywhere beneath a child's diaper. Typically, the areas of the skin that touch the diaper are most affected. Diaper rash can also be caused by infection with the fungus Candida, typically causing a bright red rash in the creases of the skin and small red spots. Less often, diaper rash is caused by bacteria.
