The most common cause of bronchiolitis in infants is the respiratory syncytial virus (RSV). Other viruses can also cause it, but RSV is responsible for the majority of cases.

Common Symptoms of Bronchiolitis
Bronchiolitis typically begins with symptoms resembling a common cold, but they can progress rapidly. Parents should be vigilant for:- Runny nose and nasal congestion
- Cough (often dry and hacking initially, may become wetter)
- Fever (usually low-grade)
- Decreased appetite and feeding difficulties
- Irritability and fussiness
- Wheezing (a whistling sound when breathing, especially exhaling)
- Rapid breathing (tachypnea)
- Flaring of the nostrils
- Retractions (skin pulling in between the ribs or at the neck with each breath)
- Grunting sounds with breathing
- Short pauses in breathing (apnea), particularly in very young infants
Causes of Bronchiolitis
The vast majority of bronchiolitis cases are caused by viruses, with respiratory syncytial virus (RSV) being the most frequent culprit. Other viruses can also lead to bronchiolitis, including adenoviruses, parainfluenza viruses, and rhinoviruses. The virus inflames and irritates the bronchioles, the tiny airways in the lungs, leading to mucus buildup and narrowed passages, making it difficult for air to flow in and out.Treatment Options and Home Care
There is no specific cure for bronchiolitis, as it is a viral infection. Treatment focuses on supportive care to help the infant breathe easier and stay hydrated. This typically includes:- Ensuring adequate fluid intake to prevent dehydration.
- Keeping the infant's nasal passages clear with saline drops and a nasal aspirator.
- Providing a cool-mist humidifier in the infant's room to help loosen mucus.
- Encouraging rest.
- Monitoring for worsening symptoms, such as increased difficulty breathing, persistent high fever, or signs of dehydration.
Preventive Measures
Preventing the spread of viruses is key to reducing bronchiolitis cases. Effective preventive measures include:- Frequent handwashing for caregivers and visitors.
- Avoiding close contact with sick individuals.
- Cleaning and disinfecting frequently touched surfaces.
- Avoiding smoking around infants, as exposure to secondhand smoke significantly increases the risk and severity of respiratory infections.
- Breastfeeding, which can provide antibodies that help protect infants from infections.
