We tend to believe that when winter is finished and spring is flourishing, colds are over. However, many people still experience respiratory tract infections in springtime, for various reasons:
- Respiratory tract infections caused either by viruses or bacteria are important factors that exacerbate asthma course in at risk populations (1, 2, 3).
- Airborne pollen exposure increases with consequences on asthma and allergic rhinitis in susceptible subjects.
- In spring, asthma medication prescriptions and emergency department visits increase (4).
- 334 million people have asthma worldwide, and 14% of the world’s children experience asthma symptoms (5).
- Seasonal rhinitis or hay fever, triggered by airborne pollen exposure, affect as much as 10% of adults and over 20% of children (6)
