Symptoms
By Mayo Clinic staffThe classic sign of croup is a loud, harsh, barking cough — which often comes in bursts at night. Your child's breathing may be labored or noisy. Fever and a hoarse voice are common, too.
When to see a doctor
Most cases of croup can be treated at home with a few simple self-care measures. However, you should seek immediate medical attention if your child:
- Makes noisy, high-pitched breathing sounds when inhaling (stridor)
- Begins drooling or has difficulty swallowing
- Seems agitated or extremely irritable
- Struggles to breathe
- Develops blue or grayish skin around the nose, mouth or fingernails
- Has a fever of 103.5 F (39.7 C) or higher
