World COPD Day on 19 November is a global effort to expand understanding of chronic obstructive pulmonary disease (COPD) and advocate for better care for patients. Currently 210 million people have the illness, according to 2007 WHO estimates. WHO predicts that COPD will become the fourth leading cause of death worldwide by 2030. Key risk factors for COPD are tobacco smoking, indoor and outdoor air pollution, and exposure to occupational dusts and chemicals.

Organized by the Global Initiative for Chronic Obstructive Lung Disease (GOLD), the Day is marked by activities implemented by health care professionals and patient groups throughout the world.
