World Asthma Day brings together health professionals and people with asthma from around the world. In France, this lung disease affects more than four million people.

Each year, more than 900 deaths and 60,000 hospitalizations related to this disease are recorded in France. The researchers note that there is not "asthma", but several forms of the disease whose study should lead to the development of new, more targeted treatments. The event was created in 1998 at the initiative of the Global Initiative for Asthma (GINA)
