Relación entre asma e infecciones virales

The factors that could explain this association are heterogeneous and sometimes contradictory. The four main causative mechanisms implicated in the association between viral respiratory infections and the subsequent development of asthma or wheezing in children are alterations in airway function and size, dysregulation (congenital and acquired) of airway tone, alterations in the immune response to infections, and the genetic variants involved in immune response. These mechanisms should be taken into account in future preventive and therapeutic strategies.
