The ATS International Conference is the most prestigious scientific meeting devoted to the presentation and discussion of new research findings and the latest clinical developments in respiratory, critical care and sleep medicine.
During the Conference, more than 13,500 attendees heard over 5,300 original research presentations related to the prevention, diagnosis and treatment of respiratory diseases such as lung cancer, chronic obstructive pulmonary disease (COPD), asthma, allergies, sleep-related disorders, cystic fibrosis, tuberculosis and many more.
