What is Bronchiolitis?

Bronchiolitis is a common lung infection in young children and infants that causes inflammation and congestion in the small airways (bronchioles) of the lungs. It’s most often caused by viral infections, with respiratory syncytial virus (RSV) being the leading culprit.

This condition primarily affects children younger than 2 years old, particularly during RSV season, which typically runs from late fall to early spring. Bronchiolitis can range from mild to severe and, in some cases, may require hospitalization.

Is Bronchiolitis the Same as Respiratory Syncytial Virus (RSV)?

While bronchiolitis and respiratory syncytial virus (RSV) are closely linked, they are not exactly the same thing. RSV is a virus—one of the many respiratory viruses—that can cause bronchiolitis, along with others like rhinovirus and influenza.

At After Hours Kids’ pediatric urgent care services, we often treat cases of bronchiolitis triggered by RSV. It’s important to note that a severe RSV infection can lead to more complicated breathing issues, especially in young infants and children with a weakened immune system.

Risk Factors for Bronchiolitis

Some children are more vulnerable to bronchiolitis than others. Risk factors include:

  • Infants younger than 6 months old
  • Premature birth
  • Exposure to cigarette smoke
  • Crowded living conditions
  • Attending daycare or having siblings who attend school
  • Pre-existing heart or chronic lung disease
  • A weakened immune system

What Are the Symptoms of Bronchiolitis in a Child?

Recognizing bronchiolitis symptoms early can make a big difference. Common symptoms include:

  • Runny nose
  • Rapid breathing or trouble breathing
  • Wheezing
  • Persistent coughing
  • Fever
  • Difficulty feeding (especially in infants)
  • Irritability and fatigue
  • Dehydration signs (like fewer wet diapers)
 

RSV symptoms typically start like a cold but can quickly escalate, making it essential to monitor your child’s breathing closely. RSV traditionally worsens between days 3-5 of symptoms.

How is Bronchiolitis Diagnosed in a Child?

A diagnosis of bronchiolitis usually involves a physical exam. Your child’s healthcare provider will listen for wheezing, observe breathing patterns, and assess overall appearance.

Tests aren’t always necessary, but in some cases, providers may recommend:

  • Nasal swab tests to detect respiratory syncytial virus (RSV)
  • Chest X-rays (if pneumonia is suspected)
  • Pulse oximetry to measure oxygen levels in the blood
 

At After Hours Kids, we’re equipped to assess and manage bronchiolitis swiftly to ensure the best outcomes for your child.

How is Bronchiolitis Treated in a Child?

Unfortunately, there is no cure for bronchiolitis; treatment focuses on supportive care. Here’s what we often recommend:

  • Ensuring your child gets plenty of fluids
  • Using a humidifier to ease breathing
  • Frequent suctioning of the nose to clear mucus
  • Monitoring for signs of trouble breathing or dehydration
  • In some cases, a nebulized breathing medication can be useful
 

In more severe cases, hospitalization might be necessary for oxygen support, IV fluids, or close monitoring.

Remember, severe RSV cases can develop quickly. If your child is struggling to breathe, appears very tired, or has bluish lips or fingertips, seek immediate medical care.

How Can I Help Prevent Bronchiolitis in My Child?

Prevention is crucial, especially during peak RSV season. Here’s how you can reduce the risk:

  • Handwashing: Wash hands frequently and thoroughly.
  • Avoid exposure: Keep your child away from sick individuals.
  • Clean surfaces: Regularly sanitize toys, countertops, and doorknobs.
  • Smoke-free environment: Avoid exposing your child to secondhand smoke.
  • Limit daycare: If possible, during RSV season for young infants.

New Ways to Protect Infants from RSV

There are now exciting new options to help protect babies from severe RSV illness. A maternal RSV vaccine is recommended for pregnant women between 32 and 36 weeks if their baby is expected to be born during RSV season (typically from fall to spring in the U.S.). This vaccine helps pass protective antibodies to the baby, offering strong protection right after birth.

In addition to the vaccine, doctors can also give infants a special antibody shot designed specifically to prevent RSV infection. Unlike traditional vaccines, this shot delivers ready-made antibodies that protect babies for several months. It is recommended for:

  • Babies younger than 8 months old who are entering or are already in the RSV season
  • Babies aged 8 to 19 months who are entering their second RSV season and have higher risk factors for serious illness
 

If a mother receives the RSV vaccine during pregnancy, her newborn may not need the antibody shot. However, if the baby is born less than two weeks after the mother’s vaccination, doctors might recommend an additional shot to ensure full protection.

After Hours Kids can guide you through prevention strategies and answer any questions about RSV immunization.
