Is COPD Contagious?

No, COPD is not contagious. Chronic Obstructive Pulmonary Disease, or COPD, is a progressive lung disease that is typically caused by long-term exposure to irritants such as cigarette smoke, air pollution, or chemical fumes. It is not caused by bacteria or viruses, so it cannot be spread from person to person through close contact or respiratory droplets. However, smoking is a major risk factor for developing COPD, so quitting smoking and avoiding exposure to lung irritants can help prevent the disease.
