Bronchitis is primarily caused by inflammation of the airways, often triggered by viral infections.
Causes of Bronchitis:
Acute Bronchitis
Acute bronchitis is usually a result of viral infections affecting the airways. Here are the common viral culprits:
- Common Cold: The viruses that cause the common cold are frequent causes of acute bronchitis.
- Influenza (Flu): Influenza viruses can lead to airway inflammation, resulting in bronchitis.
- Respiratory Syncytial Virus (RSV): RSV is a common virus, especially in children, that can cause bronchitis.
- COVID-19: The viruses that cause COVID-19 can also lead to acute bronchitis.
In some instances, a bacterial infection can also be the root cause of acute bronchitis.
Summary of Causes
| Cause | Type | Examples |
|---|---|---|
| Viral Infection | Primary | Common cold, influenza, RSV, COVID-19 viruses |
| Bacterial Infection | Secondary | Occasional instances |
It is crucial to understand that while viruses are the primary cause of acute bronchitis, bacterial infections can sometimes also be responsible. Proper diagnosis can help determine the correct course of treatment.
