What is a common symptom of croup in a child?

A barking cough is a hallmark symptom of croup, which is characterized by inflammation of the upper airways leading to a distinctive respiratory sound. This type of cough resembles the noise of a barking seal and typically indicates the presence of airway swelling. Croup usually occurs in young children and is often triggered by viral infections. The barking cough, along with stridor (a high-pitched wheezing sound), helps clinicians differentiate croup from other respiratory conditions.

Other symptoms often associated with croup may include a mild fever, but this is not as prominent as the cough. The presence of a runny nose might be observed as well, but it is not a defining characteristic of croup. Wheezing can occur in various respiratory conditions, but it is not specific to croup. The identification of the barking cough is crucial in diagnosing croup and guiding appropriate management.
