Bronchiolitis Symptoms & Diagnosis


Symptoms of bronchiolitis occur in two stages:

During the first 2-3 days the child will probably have a:

  • Runny or stuffy nose
  • Slight fever

During the next 2-3 days, the symptoms increase to include:

  • Cough (dry)
  • Fever
  • Sneezing
  • Rash
  • Red eyes
  • Fast rate of breathing
  • Difficulty breathing
  • Wheezing (making a whistling noise during breathing)
  • Bluish color in the skin, especially around the lips or nails
  • Poor feeding
  • Restlessness


To diagnose bronchiolitis, the doctor may do one or more of the following:

  • Listen to the child’s lungs to check for abnormal breathing, such as wheezing
  • Chest x-ray to check for swelling in the airways and signs of pneumonia (severe case)
  • Sample mucus from nose or throat to test for the virus that may be causing the infection
  • Blood test to determine the level of oxygen in the blood
  • Blood test for complete blood count
