Croup cough and COVID-19

Croup describes swelling of the upper airway, often with a barking cough, hoarse voice or noisy breathing. COVID-19 is an infection that can cause a wide range of respiratory symptoms, and the cough may be dry, wet or absent. A person with COVID-19 may have croup-like upper-airway symptoms, but the cough’s sound cannot identify the virus.

Fever, sore throat, runny nose, tiredness, vomiting or a known exposure can make viral infection more likely, but symptoms overlap with a common cold, bronchiolitis and acute bronchitis. Testing may help when available and appropriate; a negative result does not replace assessment of difficult breathing.

Keep the child calm and upright if coughing is harsh, offer fluids, improve ventilation and wash hands often. Avoid close contact with vulnerable household members while the illness is active, and follow current local advice about testing and staying home. Do not use steam or unprescribed antibiotics for a barking cough.

Record when symptoms began, any exposure, temperature changes and whether breathing is noisy when the child is resting. This information helps a clinician decide whether testing, treatment or observation is appropriate.

Seek emergency help if breathing is laboured, the ribs or neck pull in, lips look blue or grey, the child cannot swallow, becomes unusually drowsy, or has noisy breathing while resting. Adults also need urgent care for severe breathlessness, chest pain, confusion or rapidly worsening symptoms.

Ask whether testing is recommended, whether the symptoms fit croup or another infection, and how long to limit contact with others. Mention age, medical conditions, vaccination history, known exposure, fever, breathing noise and any medicines already given.
