An infection of one or more parts of the urinary system. The urinary system includes the kidneys, tubes that join the kidneys to the bladder (ureters), bladder, and tube that leads from the bladder to the outside (the urethra).
Infection usually occurs from bacteria from feces on the skin that enter the urethra, particularly in girls. Urinary tract infection is more common in children with constipation and who do not fully empty their bladders during voiding. Less commonly, it is caused by bacteria from the bloodstream entering the kidneys in young infants. Urinary tract infection is not passed from one person to another.
Children with signs or symptoms of urinary tract infection should be evaluated by a health professional. Teachers/ caregivers and the family should implement the advice of the health professional, which may include offering fluids frequently, giving prescribed medication, and gentle wiping after using the toilet.
