Acute Bronchitis in Children

What is acute bronchitis in children?

Bronchitis is an inflammation of the large breathing tubes (bronchi) in the lungs. The illness can be short-term (acute) or long-term (chronic). Acute bronchitis means that the symptoms often develop quickly and don’t last long. Most cases are mild.

What causes acute bronchitis in a child?

Acute bronchitis is most often caused by a viral infection. It may also be caused by bacteria or things, such as dust, allergens, strong fumes, or tobacco smoke.

In children, the most common cause of acute bronchitis is a virus. The illness may develop after a cold or other viral infection in the nose, mouth, or throat (upper respiratory tract). Such illnesses can spread easily from direct contact with a person who is sick.

Which children are at risk for acute bronchitis?

Children who have a higher chance of developing acute bronchitis are those who have:

  • Chronic sinusitis

  • Allergies

  • Asthma

  • Enlarged tonsils and adenoids

  • Exposure to secondhand smoke

  • Have other serious health conditions

What are the symptoms of acute bronchitis in a child?

These are the most common symptoms:

  • Dry or mucus-filled cough

  • Vomiting or gagging

  • Runny nose, often before a cough starts

  • Chest congestion or pain

  • An overall body discomfort or not feeling well

  • Chills

  • Slight fever

  • Back and muscle pain

  • Wheezing

  • Sore throat

These symptoms often last 7 to 14 days. But the cough may continue for 3 to 4 weeks. These symptoms may look like other health problems. Make sure your child sees their healthcare provider for a diagnosis.

How is acute bronchitis diagnosed in a child?

Your child’s healthcare provider can often diagnose acute bronchitis with a health history and physical exam. In some cases, your child may need tests to rule out other health problems, such as pneumonia or asthma. These tests may include:

  • Chest X-rays. This test makes images of internal tissues, bones, and organs.

  • Pulse oximetry. An oximeter is a small device that measures the amount of oxygen in the blood. For this test, the healthcare provider puts a small sensor (like a clip) on your child's finger or toe. When the device is on, a small red light can be seen in the sensor. The sensor is painless, and the red light does not get hot.

  • Sputum and nasal discharge samples. These tests can find the germ causing an infection.

How is acute bronchitis treated in a child?

Treatment will depend on your child’s symptoms, age, and general health. It will also depend on how severe the condition is.

In nearly all cases, antibiotics shouldn't be used to treat acute bronchitis. That’s because most of the infections are caused by viruses. Even children who have been coughing for longer than 8 to 10 days often don't need antibiotics. Antibiotics aren't used unless your child has a bacterial infection.

The goal of treatment is to help ease symptoms. Treatment may include:

  • Plenty of rest

  • Acetaminophen or ibuprofen (for children over 6 months) for fever and mild pain, if directed by your child’s healthcare provider

  • Cough medicine for children over 4 years old, if directed by your child’s healthcare provider

  • More fluids

  • Cool-mist humidifier in your child’s room

Talk with your child’s healthcare provider before giving over-the-counter cough and cold medicine to your child. The American Academy of Pediatrics does not advise giving these medicines to children younger than 4 years old because they may cause harmful side effects. For children between ages 4 and 6, only use over-the-counter products when advised by your child's healthcare provider. In most cases, also don’t give antihistamines. They can dry up the secretions. That can make the cough worse.

Never give aspirin to a child or teen. It could cause a rare but serious condition called Reye syndrome. This is a rare but very serious disorder. It most often affects the brain and the liver.

What are possible complications of acute bronchitis in a child?

Most children who have acute bronchitis will get better without any problems. But the illness can lead to pneumonia.

How can I help prevent acute bronchitis in my child?

You can help prevent acute bronchitis by stopping the spread of viruses that may lead to it. Take these steps:

  • Teach your child to cover their nose and mouth when coughing or sneezing.

  • Make sure your child washes their hands often.

  • Keep your child up-to-date on all vaccines, including the yearly flu shot.

  • Keep your child away from others who are sick. If your child is sick, keep them away from others.

When should I call my child’s healthcare provider?

Call your child’s healthcare provider right away if your child’s symptoms get worse, if new symptoms develop, or if they:

  • Have a high fever

  • Can't keep liquids down

  • Aren't eating or drinking

  • Aren't having wet diapers

Call 911

Call 911 if any of the following occur:

  • Has trouble breathing

  • Turns blue in color, especially the lips or fingertips

  • Is breathing very fast

  • Know the reason for the visit and what you want to happen.
