A sudden, barking cough in a child can be surprisingly alarming. That strange, seal-like sound often signals croup, a common respiratory condition in young children. Understanding what croup is can turn a frightening night into a manageable situation.
What Is Croup?
Croup is an infection that affects the upper airway, mainly the voice box (larynx) and windpipe (trachea). It’s most common in children between six months and three years old, though older kids can get it too. The hallmark of croup is a “barking” cough, often accompanied by a hoarse voice and noisy breathing called stridor.
Key Facts About Croup
-
Viral Causes: Most cases are caused by parainfluenza viruses, not bacteria.
-
Seasonal Trends: Croup is more common in fall and early winter.
-
Mild to Severe: Symptoms can range from a slight cough to severe breathing difficulty.
-
Contagiousness: It spreads through coughs and sneezes, so handwashing and avoiding close contact help prevent it.
-
Age Factor: Children’s smaller airways make croup more dramatic and worrisome than in adults.
What Are the Symptoms?
Croup usually starts like a common cold, with a runny nose and mild fever. Within a day or two, the distinctive symptoms appear:
-
Barking cough
-
Hoarse voice
-
Stridor (a high-pitched wheezing sound)
-
Difficulty breathing in severe cases
-
Symptoms often worsen at night
How Is Croup Diagnosed?
Doctors usually diagnose croup based on a child’s symptoms and a physical exam. Imaging or lab tests are rarely needed unless symptoms are severe or unusual.
How Do You Treat Croup?
Most cases of croup are mild and can be managed at home, but it’s important to know what works:
-
Comfort Measures: Keep the child calm—crying can make breathing harder.
-
Humidity and Steam: Sitting in a steamy bathroom or using a cool-mist humidifier can ease symptoms.
-
Medication: In more severe cases, a doctor may prescribe corticosteroids to reduce airway swelling.
-
Emergency Signs: If your child struggles to breathe, has bluish lips, or extreme lethargy, seek immediate medical care.
Can Croup Be Prevented?
While you can’t guarantee a child won’t get croup, some measures may lower the risk:
-
Frequent handwashing
-
Avoiding close contact with sick children
-
Keeping vaccinations up to date
