|---|---|---|
| Infectious | Viruses (such as influenza virus, new coronavirus), bacteria | 35% |

| Treatment | Applicable situations | efficient |
|---|---|---|
| Glucocorticoids | active stage of inflammation | 60%-70% |
| antifibrotic drugs | idiopathic pulmonary fibrosis | 40%-50% |
| Oxygen therapy | patients with hypoxemia | Symptom relief rate 80%+ |
Prevention advice:
1. Avoid smoking and second-hand smoke exposure;
2. Occupational protection (such as wearing a mask when exposed to dust);
3. Regular physical examination, especially for those with family medical history;
4. Get vaccinated against influenza and pneumonia.
5. Recent hot topics
