What is a common feature of the cough associated with croup?

The cough associated with croup is typically described as barking and harsh. This distinctive sound occurs due to inflammation and narrowing of the airway, which is characteristic of croup, commonly caused by viral infections. The inflammation affects the larynx and trachea, leading to the characteristic cough that can resemble a seal's bark.

This barking quality differentiates it from other types of coughs that may be wet, gurgling, or dry and hoarse. While a deep and loud cough might indicate a different respiratory issue, the hallmark feature of croup is its harsh, barking sound. Recognizing this specific cough can be critical in diagnosing and managing croup effectively.
