Don’t Let Your Breath Be Your Warning: Understanding the Hidden Contagiousness of Croup When a child suddenly lets out a harsh, barking cough—barking like a small dog—it’s often terrifying for parents. This classic symptom signals croup, a common childhood condition often dismissed as just “a bad cold.” But the truth is, croup isn’t merely annoying—it’s contagious, with subtle spread mechanisms that many parents overlook. ### What Is Croup—and Why Should You Be Concerned? Croup, or laryngotracheobronchitis, is a viral infection affecting the upper airway, causing swelling and stridor (a high-pitched breathing sound). While typically mild in healthy children, croup can be contagious, especially during the early stages when symptoms flare. Understanding how the virus spreads—and when to act—can minimize outbreaks in homes, schools, and childcare settings.
