Natural History of Bronchiectasis Study

This observational study aims to understand more about bronchiectasis, a condition where your airways are inflamed and abnormally wide, leading to chronic infections. Researchers want to identify the causes and underlying conditions associated with bronchiectasis, especially those not related to cystic fibrosis. You may be able to join if you are 5 years or older and have chronic or recurring respiratory infections. The study will follow participants for at least 5 years to observe how their disease progresses. This study is not testing any specific treatments or interventions.
