Acute bronchiolitis is a lung infection that affects small airways, mostly in infants and young children. The primary cause is viral infections, particularly:
- Respiratory Syncytial Virus (RSV) – The most common virus responsible for bronchiolitis, especially in children under two.
- Influenza Virus – Can lead to inflammation in the airways, making breathing difficult.
- Adenovirus – Causes severe symptoms and prolonged illness.
- Parainfluenza Virus – Affects the respiratory tract and can lead to wheezing.
- Human Metapneumovirus – Similar to RSV, it can cause significant breathing issues.
Risk Factors
- Premature birth – Underdeveloped lungs make babies more vulnerable.
- Weakened immunity – Infants and older adults are at higher risk.
- Exposure to cigarette smoke – Irritates airways, increasing infection risk.
- Crowded living conditions – Increases virus spread.
- Lack of breastfeeding – Reduces natural antibodies that fight infections.
Symptoms to Watch For
- Coughing and wheezing
- Shortness of breath
- Fever
- Nasal congestion
- Rapid breathing
Prevention Tips
- Wash hands frequently to reduce virus spread.
- Avoid close contact with sick individuals.
- Keep indoor air clean and free from smoke.
- Get annual flu shots and other recommended vaccines.
Recognizing early symptoms and seeking medical help can prevent complications.
