What are the symptoms of a urinary tract infection (UTI) in children?

Children with urinary tract infections (UTIs) will often complain about symptoms of pain or burning when they urinate. They may also have a fever, poor appetite, vomiting, abdominal pain, foul-smelling urine or blood in their urine. If you are concerned your child may have a UTI, bring him or her to the doctor.
Symptoms of a urinary tract infection (UTI) in children include the following:
  • low fever
  • irritability
  • frequent urination
  • pain or burning when urinating
  • strong odor to the child's urine
  • urine that is cloudy or has some blood in it
  • new day wetting or night wetting in a child who had previously been toilet trained
If the infection spreads to the kidneys, the child may also have high fever and back pain and experience vomiting.

Girls, especially between ages 4 and 8, are more likely to have urinary tract infections than boys. Infants who are born with an abnormality of their urinary tract have an increased chance of getting a UTI.
Signs and symptoms of UTIs include:
  • dysuria (burning on urination);
  • urinary frequency;
  • urinary urgency;
  • foul smelling, cloudy urine;
  • incontinence (bed wetting episodes); 
  • fever.
