What is bronchitis?

Acute bronchitis is an inflammation of the lining of the bronchial tubes, the airways that lead into the lungs to deliver oxygen.

Viruses, such as rhinovirus, adenovirus, parainfluenza virus and influenza virus, are the most common causes of bronchitis in children.

In contrast, bacteria rarely cause bronchitis in children. Most people will have bronchitis at some point in their life.

Children with allergies or asthma, and those exposed to a lot of cigarette smoke or other air pollution seem to be at an increased risk of developing bronchitis.

Symptoms

Symptoms and signs

Bronchitis usually starts with symptoms of the common cold (an upper respiratory infection) such as stuffy nose, sniffles and sneezing.

After a few days the symptoms move into the chest. At first there is a dry cough due to irritation of the bronchial tubes, but gradually, more and more mucus is produced in the airways, and the cough becomes a wet-sounding (productive) cough.

Occasionally the child with bronchitis will have a fever, headache and soreness in the chest, especially with coughing.

Some children have difficulty breathing and develop asthma-like symptoms, taking longer than normal to breathe out (exhale).

Children who are already known to have asthma will often develop more serious asthma symptoms when they have bronchitis. In the case of chronic bronchitis, the only symptom may be a persistent cough.

Complications

Bronchitis may develop further into an inflammation of the lungs (pneumonia). The child will then have more difficulty breathing, and appear more ill often with fever above 102 degrees.

If you suspect an inflammation of the lungs, you should contact the doctor. Any child with pneumonia will have a much harder time breathing, and in cases of known asthma, the child's usual asthma medications may not seem to work. You should call your doctor if this ever occurs.

Home treatment

Treatment / What you should do

In bronchitis caused by a virus, antibiotics (which kill bacteria) are of no help.

There are no routine medications available to kill the virus. There are however, treatments that may help your child feel better.

Encourage your child to drink a lot of fluids, since this helps loosen up the mucus in the breathing tubes. Warm drinks may also help to soothe a sore throat and quiet the dry cough.

It may help to humidify the air in the bedroom by using a humidifier or by hanging up wet towels over a chair near a radiator.

Expectorants may also be used to loosen the mucous, or help dry up the secretions, and cough suppressants may help your child get a good night's sleep.

If your child is struggling to breathe, his overall condition is worsening, or if his fever becomes very high, you should contact the doctor.

If your child has a bacterial infection, the doctor will prescribe an antibiotic. If your child seems to have obstructed respiratory passages (wheezing), the doctor may prescribe an asthma medicine.

If your child is known to have asthma, his asthma medication should be increased according to the child's "Asthma Action Plan".

Prevention

It is not easy to prevent your child from developing bronchitis, since it may occur after a cold or other respiratory infection caused by a virus. However, since these viruses are spread by droplets in the air from an infected person and by hand-to-hand contact, frequent hand washing may make it less likely that your child will become infected with a virus.

You should keep your child home from daycare or school when they have fever, and also when they have a severe cold, since the risk of infecting other children is high and they will not feel like being around other children anyway.

Children who grow up in homes where there are smokers tend to catch colds more often than children from smoke-free homes. Therefore, always avoid exposing your child to second-hand smoke as much as you can.
