WEDNESDAY, Sept 30, 2026 (HealthDay News) — As many parents know, urinary tract infections (UTIs) can strike babies and young children too.
This week, the nation's leading pediatricians' group issued its first update since 2011 on diagnosing and treating these infections.
The new American Academy of Pediatrics (AAP) guidelines urge that any child between 2 months and 5 years of age be tested for a UTI within 72 hours of developing a fever with no apparent cause.
“UTIs are one of the most common bacterial infections in infants and young children but reaching a diagnosis can be challenging,” Dr. Brian Alverson, chairperson of the guideline panel, said in an AAP news release.
“The updated guideline aims to give clinicians clearer, more up-to-date direction for care based on evidence," he said.
By age 6, up to 7% of girls and 2% of boys will experience a UTI, and in 30% of cases the infection will recur, according to the AAP. The infections are typically detected via urine tests, and antibiotics can usually clear up a pediatric UTI.
However, UTIs in infancy and childhood can have serious consequences, including damage to the kidneys, the AAP noted.
The new guideline expands the clinical focus of UTIs in children from 8 days to 5 years of age. The prior guideline ranged from 2 months to 2 years of age.
Regarding diagnosis, the guidelines recommend that doctors use a combination of tools, such as assessing symptoms and conducting urinalysis. If UTIs recur, doctors should consider constipation and bladder-bowel dysfunction as possible contributing factors.
For treatment, a shorter course of antibiotics (seven days or fewer) is recommended. Longer courses of the drugs are recommended only for use in infants or tough-to-treat cases, or for children deemed to be at high risk.
The new guidelines stressed there's no "one-size-fits-all" for the care of pediatric UTIs.
“We recognize that physicians must make decisions on the unique needs and symptoms of each individual patient,” Dr. David Hains, vice chairperson of the guideline panel, said in the news release. “This decision-making ideally occurs through a shared process that considers the patient’s and caregiver’s values and preferences.”
