Acute Laryngotracheobronchitis

Acute laryngotracheobronchitis, popularly known as croup, is an infection, almost always of viral origin, that inflames the larynx, trachea, and bronchi. It affects mainly young children and disrupts the passage of air through the airways.

When to seek care? An evaluation is important in the presence of the characteristic barking cough, hoarse voice, a harsh sound when inhaling, or difficulty breathing, especially if the child becomes agitated or the chest is drawn in with breathing.

Frequent symptoms: dry cough, hoarseness, and, often, a marked worsening of symptoms during the night.

Which specialist treats it? The pediatrician is the professional best suited to evaluate it, with support from the pediatric pulmonologist in selected cases that require it. At any sign of breathing difficulty in a child, the most prudent course is to seek medical evaluation without delay.
