- Respiratory viruses have a pooled prevalence of 33.9% in children and 23.0% in adults with stable asthma.
- During acute asthma episodes, viral prevalence rises to 58.8% in children and 49.9% in adults.
- Rhinovirus is the most common virus identified, especially in acute asthma (45.0% in children vs. 21.2% in adults).
- Specific viruses vary by age: RSV and bocavirus are more common in younger children, while coronavirus and influenza are more frequent in adults.
- Certain viruses like influenza B and adenovirus in children, and influenza A and parainfluenza 2 in adults, are associated with more severe acute asthma attacks.
- A positive viral test during acute asthma may have limited diagnostic value and could benefit from complementary biomarkers.
