A urinary tract infection (UTI) is a problem that happens when germs (called bacteria) get into the urinary tract and cause an infection.
Your child's urinary tract is the system that makes urine and carries it out of your child's body. It includes the bladder and the kidneys and the tubes that connect them. Most UTIs are bladder infections.
UTIs in children must be treated right away. A UTI that is not treated quickly can lead to a kidney infection.

Sometimes the doctor may give your child a shot of antibiotics. This can happen if your child is younger than 3 months, is too nauseated or sick to take oral medicines, or has an impaired immune system. Or your child may need antibiotics given through a vein (I.V.). This is given in a hospital. After your child's fever and other symptoms improve and your child is feeling better, the doctor may give your child oral antibiotics.
