Croup is one of the most common respiratory (breathing) infections in young children. Children with croup usually have a very distinctive barking cough and hoarseness.
Most cases of croup are mild, but it can sometimes cause serious breathing problems for babies and small children. Here is all you need to know about croup, its causes and how to manage it when your child is sick.
Croup is a contagious viral infection that causes swelling in the upper airway, including the voice box (larynx) and windpipe (trachea). This infection can make the airway swell and narrow, leading to a unique barking cough, hoarseness and breathing problems.
Croup usually affects children under 3 years old and isn’t seen as often in older children. This is because their windpipes get larger and swelling is less likely to get in the way of their breathing.
These viruses spread easily through the air when someone who is infected coughs or sneezes. Your child can also get croup by touching infected surfaces or objects (i.e., tabletops and toys).
Croup is usually seen in babies and children between 6 months and 3 years. Some things that can increase the chance of getting croup include:
At first, your child may have a stuffy or runny nose, a low fever and a slight cough. These symptoms get worse as the virus moves from the nose to the lungs.
These signs could be:
Croup often becomes worse at night and may last several days. However, the cough may stick around for a few weeks.
Croup, RSV and whooping cough are all respiratory illnesses, but their causes, symptoms and treatment are different.
RSV can affect people of all ages but is especially severe in infants and older adults. RSV can cause runny nose and cough and sometimes can cause the barking cough of croup. RSV often affects the lungs while croup usually only involves the upper airway.
Whooping cough (Pertussis) is caused by bacteria, not a virus. While it also causes a very particular cough, whooping cough can often make your child throw up after a long coughing spell. In some babies it can cause them to stop breathing. There are no medicines or vaccines to prevent croup, but the good news is that there is a vaccine to prevent whooping cough, and antibiotics to stop the spread of whooping cough among people known to be exposed to the bacteria.
Health care providers can usually tell if your child has croup by listening to their symptoms and doing a physical exam.
They might ask about your child’s symptoms and how long they’ve been going on. They’ll check your child’s breathing, listen for certain sounds and might use a light to look at their throat.
Usually, other tests like X-rays or specific viral swabs aren’t needed.
Treatment will depend on your child’s age, symptoms and how serious the condition is. If your child has a history of respiratory problems or was born prematurely, that may also affect their treatment.
Mild symptoms can usually be treated at home. Here are some tips on what you can do to make your child more comfortable as they heal:
If your child’s symptoms don’t improve or get worse, call their provider. Some children may need a breathing treatment or steroid medication to calm swelling in the airway.
Call 911 or take your child to the closest emergency department if your child:
Croup is spread just like the common cold, so it is difficult to prevent.
Keep your child home from school or daycare when they’re ill or if it’s known that an illness is spreading.
Regular hand washing and teaching your child to sneeze and cough into their elbow can help stop the spread of viruses. Also try to get your child to avoid touching their face, especially their nose and mouth.
Make sure your child is up-to-date with all recommended shots. These immunizations can help reduce the risk of some of the infections that can lead to croup.
