What Information Is Available for Infants with Bronchiolitis?

Bronchiolitis is a common respiratory illness that affects infants and young children. It is caused by a viral infection and results in inflammation and narrowing of the small airways in the lungs. This can make breathing difficult for a baby, leading to wheezing, coughing, and rapid breathing. It is a severe condition requiring hospitalization. 


To help parents understand what bronchiolitis is and how it affects their child, we've compiled a comprehensive guide that covers everything from symptoms and causes to treatment options and preventive measures. 


Symptoms and Causes of Bronchiolitis


The symptoms of bronchiolitis can develop slowly over several days but can rapidly worsen in some cases. The most common symptoms include:

  • Wheezing or whistling sound when breathing
  • Rapid breathing or shortness of breath
  • Coughing
  • Congestion or runny nose
  • Fatigue or irritability
  • Poor appetite or refusal to eat


These symptoms are caused by the viral infection that inflames the small airways in the lungs, making it difficult for a baby to breathe. The most common causes of bronchiolitis are respiratory syncytial virus (RSV), human metapneumovirus, adenovirus, and parainfluenza virus.


Diagnosing Bronchiolitis


Diagnosing bronchiolitis usually involves a physical examination and a review of a baby's symptoms. A doctor may also listen to a baby's chest to hear if there is any wheezing or other signs of a lung infection. Sometimes, a doctor may order a chest X-ray to help diagnose the condition.


Treatment for Bronchiolitis


Bronchiolitis treatment options are available to help relieve symptoms and improve breathing. The most common treatments include:

  • Oxygen therapy: If a baby is having trouble breathing, a doctor may prescribe oxygen therapy to help increase the amount of oxygen in the blood.
  • Bronchodilators: These medications help open the airways and relieve wheezing symptoms and shortness of breath.
  • Nebulizer treatments involve using a machine that converts medication into a mist. Then the patient inhales it to help relieve symptoms.
  • Steroids: In some cases, a doctor may prescribe steroids to help reduce inflammation and relieve symptoms.
  • Antibiotics: If a baby has a secondary bacterial infection, a doctor may prescribe antibiotics to treat it.

It is important to follow a doctor's instructions and seek medical attention if a baby's symptoms worsen or they have trouble breathing.


Preventing Bronchiolitis


There is no surefire way to prevent bronchiolitis in infants, but there are steps parents can take to reduce a baby's risk of getting sick. These include:

  • Washing hands frequently: This is one of the most effective ways to reduce infection.
  • Keeping a baby away from sick people.
  • Avoiding close contact with other children.
  • Avoiding exposure to smoke: It can worsen bronchiolitis symptoms, so it is essential to avoid exposure to second-hand smoke.


Differentiate Between Bronchiolitis and Bronchitis?


Bronchiolitis and bronchitis are two common respiratory illnesses that can affect infants and children. While they both involve inflammation and narrowing of the airways, there are essential differences between them.


Bronchiolitis in infants is a viral infection that primarily affects infants and young children's small airways, or bronchioles. It is most commonly caused by the respiratory syncytial virus (RSV) and usually occurs in winter. Symptoms of bronchiolitis include a runny nose, cough, wheezing, and shortness of breath. In severe cases, infants may have difficulty breathing and require hospitalization for treatment.


Conversely, bronchitis is an inflammation of the larger airways, or bronchi, in the lungs. It can be caused by both viral and bacterial infections and is characterized by a persistent cough and increased mucus production. Bronchitis can be acute (short-lived) or chronic (ongoing) and is more common in older children and adults. Acute bronchiolitis is a respiratory illness that affects infants and young children, typically between the ages of 3 months and 2 years old


The critical difference between bronchiolitis and bronchitis lies in the location and severity of the airway inflammation. While bronchiolitis primarily affects the small airways, bronchitis primarily affects the larger airways. Additionally, it is often more severe in infants and young children and can lead to hospitalization, while bronchitis is typically less intense and can often be treated at home.


How To treat Bronchiolitis at Home?


Usually, bronchiolitis can be treated at home with supportive care and over-the-counter medications. Some of the most effective ways to treat bronchiolitis at home include:

  1. Increased fluid intake: Encouraging infants to drink plenty of fluids can help relieve symptoms and prevent dehydration. Offer breast milk, formula, or water, depending on the age and feeding habits of the infant.
  2. Humidification: Adding moisture to the air can help relieve symptoms by reducing the thickness of mucus in the airways. This can be achieved through a humidifier or by taking the infant into a bathroom with the shower running.
  3. Over-the-counter medications: Over-the-counter decongestants, cough syrup, and pain relievers can help relieve symptoms and make the infant more comfortable. However, it is essential to consult a pediatrician before administering any medication to an infant, as some medicines may not be safe for young children.
  4. Rest: Encouraging the infant to rest and sleep as much as possible can help speed recovery and reduce symptoms.


In severe cases of bronchiolitis, infants may need to be hospitalized for treatment. Bronchiolitis treatment may involve oxygen therapy, nebulizer treatments, and intravenous fluids to help relieve symptoms and prevent complications.




Bronchiolitis is a common respiratory problem in infants that affects the smallest air tubes in the lungs, known as bronchioles. This condition is caused by a viral infection and is most common during the cold and flu season. Therefore, parents and caregivers need to be aware of the symptoms of bronchiolitis, which include cough, wheezing, and difficulty breathing. Bronchiolitis can be differentiated from bronchitis as the former is specific to infants and young children, while bronchitis can affect people of all ages. In addition, several home treatments can help alleviate symptoms, such as keeping the baby hydrated, using a cool-mist humidifier, and avoiding exposure to second-hand smoke.


In severe cases, a doctor may prescribe medication such as bronchodilators or corticosteroids to help relieve symptoms. Therefore, consult an expert doctor if you suspect your child may have bronchiolitis, as it can sometimes progress to a more serious condition if left untreated.
