croup

by Milly Chen

the complete guide to the childcare exclusion period for croup in Australia — how long to keep your child home, symptoms to watch for, and when they can return.

exclusion period

no exclusion required unless the child is unwell — croup is not a notifiable condition

symptoms

  • barking cough (often worse at night)
  • hoarse voice
  • noisy breathing (stridor)
  • fever
  • difficulty breathing in severe cases

incubation period

2-6 days

contagious period

the underlying viruses that cause croup are contagious during the first few days of illness, but croup itself is a symptom rather than a specific disease.

notes for parents

croup is caused by viral infections (usually parainfluenza virus) that cause swelling of the upper airway. it is most common in children aged 6 months to 3 years. seek medical attention if your child has difficulty breathing or stridor at rest.
