A UTI (urinary tract infection) is an infection that involves the kidney (pyelonephritis), bladder (cystitis) or asymptomatic bacteriuria, when children have bacteria in their urine but no symptoms.
Classic symptoms can include painful, burning urination (dysuria); frequent urination; cloudy urine; fever; and back pain. Younger infants and toddlers may just have fever and irritability.
If you ever think that your child might have a UTI, a visit to your pediatrician, who will likely perform a urinalysis and urine culture, would be a good idea.
