What should you know about bronchiolitis bacterial infection?

Bronchiolitis affects the small airways in a baby's or young child's lungs. Swelling and mucus can make breathing noisy or fast, and a cough may interfere with feeding. A bacterial infection can occur alongside another illness, but bronchiolitis itself does not automatically call for antibiotics. A clinician considers the child's age, examination findings, breathing effort, hydration, and overall behaviour before deciding what is happening.

Offer frequent small feeds or drinks if the child can manage them, keep the child upright while awake, and clear visible nasal mucus gently. Avoid smoke and avoid giving medicines that have not been recommended for that child. Record changes in feeding, wet nappies, temperature, cough, and breathing so a clinician can assess the pattern. A child health consultation can help distinguish bronchiolitis from pneumonia or another cause of breathing difficulty.

Seek urgent medical help if the child is struggling for each breath, has pauses in breathing, looks blue or grey around the lips, is unusually difficult to wake, or cannot drink. Arrange prompt assessment when breathing is becoming faster or harder, feeds are much smaller, or wet nappies are clearly reduced. Trust a concerning change in appearance even when the temperature is not high.

Ask whether the examination suggests bronchiolitis alone or another infection, how to judge hydration, and which breathing signs should trigger emergency care. You can also ask whether any prescribed treatment is appropriate and when the child should be reviewed.
