The specialist has warned that spring will be moderate to intense for people with allergies, and their symptoms will be more persistent The main cause of this situation is the extremely high temperatures recorded during the winter and the large amount of rainfall in March, "which will cause the pollen to remain in the air for longer," she explains. 

Experts warn that the number of people suffering from allergies has increased in recent years. This is due to various factors such as climate change, genetic predisposition, pollution and patient accessibility to specialists, which makes it easier for these conditions to be diagnosed. 

According to Dr Marta Viñas, approximately 25% of the general population suffers from rhinitis with or without conjunctivitis, and 12% suffer from bronchial asthma. In children, cases of allergic asthma have increased, with a peak incidence between the ages of 5 and 15 years.

As the UIC Barcelona lecturer and CST professional also explains, the impact of climate change on allergies is becoming increasingly evident. In this regard, Dr. Viñas pointed out that recent reports suggest that rising temperatures could lead to an increase in pollen production and the amount of allergens in pollen grains, extending the duration of the pollen seasons. “This phenomenon aggravates symptoms in people suffering from allergies and leads to the appearance of new sensitisations in the general population,” she added.

Regarding existing treatments, the specialist explained that specific immunotherapy or allergy vaccines are the only therapies capable of modifying the progression of the disease. She also noted that, in recent years, the profile of the patient has changed and is increasingly polysensitised, complicating diagnosis and treatment. In this context, Dr Viñas emphasised that precision medicine has been "a revolution for allergology, allowing the development of personalised vaccines based on molecular diagnostics.”
