An estimated 300 million people worldwide are living with asthma, a chronic disease that inflames and narrows the airways of the lungs, causing wheezing, breathlessness, chest tightness and coughing. Globally, an estimated 15 million years of life are lost each year due to asthma-related disability or early death. Asthma is a leading cause of hospitalization and missed school and work days in the United States, and managing the condition can be costly for families and health care systems.
