Official title: Clinical Evaluation of Surgical Face Mask Efficacy in Reducing Asthma and Rhinitis Symptoms in Birch-allergic Subjects in ALYATEC Environmental Exposure Chamber

Status Completed

There is no clinical evidence that face masks are efficient in birch pollen-induced asthma. As the use of face masks has become widespread worldwide to limit the spread of SARS-CoV-2, this study aims to demonstrate the clinical efficacy of medical masks in patients allergic to birch in the same way that clinical trial with drugs.
