UTIs are treatable, but children need the right assessment. A urinary tract infection can involve the bladder or kidneys. Medical review and urine testing help avoid missed infection, unnecessary antibiotics, and delayed care in babies or unwell children.

What is it?

A urinary tract infection, or UTI, is an infection in the urine system. It can involve the bladder, kidneys, or the tubes that carry urine.

Symptoms vary by age. Diagnosis usually needs a urine test, and treatment decisions depend on age, symptoms, urine results, and how unwell the child is.

Symptoms and signs

  • Fever, pain or burning when passing urine, or passing urine more often.
  • Urgency, new daytime accidents, new bedwetting, or lower abdominal pain.
  • Back or side pain, vomiting, poor appetite, or tiredness.
  • Babies may have fever, poor feeding, irritability, vomiting, or poor weight gain.
  • Smelly or cloudy urine may occur, but diagnosis should not rely only on smell or colour.

Common causes and triggers

  • UTIs usually happen when bacteria enter and multiply in the urine system.
  • Constipation, holding urine for long periods, and bladder-emptying problems can contribute in some children.
  • Some children need further review if UTIs recur, involve fever, or affect the kidneys.
  • Lower abdominal pain can have many causes; it is not always a UTI.

Home management

  • Seek medical review if UTI is suspected, especially with fever, vomiting, back pain, recurrent symptoms, baby age, or child looking unwell.
  • Encourage fluids unless a doctor has advised fluid restriction.
  • Do not delay urine testing if the doctor advises it.
  • Complete prescribed treatment if antibiotics are given.
  • Arrange follow-up if symptoms recur, fever persists, pain continues, or the child is not improving as expected.

What to avoid

  • Do not self-start leftover antibiotics.
  • Do not ignore fever without an obvious source, especially in babies and young children.
  • Do not rely only on urine smell, colour, or home judgement to diagnose UTI.
  • Do not delay care in babies, children with vomiting, or children who look very unwell.
  • Do not assume all lower abdominal pain is UTI.

School and daycare guidance

A child can usually return when fever-free, comfortable, drinking well, and able to use the toilet or manage care needs, following doctor and school or daycare policy. Keep the child home if fever, vomiting, significant pain, or poor drinking continues.

Important facts

  • Diagnosis usually needs a urine test; symptoms alone may not be enough.
  • Treatment may include antibiotics if UTI is confirmed or strongly suspected; the doctor decides based on the full picture.
  • Fever with UTI symptoms may suggest a higher infection and needs timely review.
  • Recurrent UTIs should be discussed with a paediatrician.

Red flags / when to seek urgent medical care

Seek urgent medical care if UTI is possible with any of these signs:
  • Baby under 3 months with fever or suspected UTI.
  • High fever, child very unwell, vomiting, poor drinking, or dehydration.
  • Back or flank pain, blood in urine, or severe abdominal pain.
  • Drowsy, confused, difficult to wake, or unusually weak.
  • Recurrent UTIs or symptoms not improving after treatment starts.
  • Parent is worried, especially in a baby or medically vulnerable child.
