Croup - Topic Overview
What is croup?
Croup is a common
respiratory problem in young children. It tends to
occur in the fall and winter. Its main symptom is a harsh, barking cough. Croup
causes swelling and narrowing in the voice box, windpipe, and breathing tubes
that lead to the lungs. This can make it hard for your child to breathe.
An attack of croup can be scary, but it is rarely serious. Children
usually get better in several days with rest and care at home.
What causes croup?
Croup usually occurs a few days
after the start of a cold and is usually caused by the same viruses that cause
the common cold. Croup is contagious. The germs that cause it can be passed
from one person to another through coughing and sneezing and through close
contact. Regular hand-washing and limiting contact with others can help prevent
the spread of croup.

and get worse at night. Sometimes children have croup attacks that wake them up
in the middle of the night for a couple of nights in a row. Unless the illness is severe, a child with croup is usually alert and active. The child's temperature is usually normal or only slightly higher than normal.
The illness usually improves in 2 to 5 days.
How is croup diagnosed?
Your doctor will probably
be able to tell whether your child has croup based on your child's symptoms and a physical exam. The doctor may be able to identify the barking cough of
croup over the phone.
The doctor may place a small clip called a
pulse oximeter on your child's finger, toe, or earlobe
to make sure that enough oxygen is reaching the blood.
