World COPD Day is a global awareness initiative held annually on the third Wednesday of November to highlight the burden of chronic obstructive pulmonary disease (COPD), promote prevention, and emphasise the importance of early diagnosis and effective management. Organised by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) in collaboration with health care professionals and patient groups worldwide, the day fosters knowledge-sharing and advocacy to reduce the global impact of COPD. Each year, GOLD selects a central theme and coordinates the development and dissemination of awareness materials, while local activities are led by health workers, educators and communities committed to making a difference.
