Chronic obstructive pulmonary disease (COPD) is a growing global health problem. Each year more than 3.5 million people die from COPD, and it is now one of the top causes of death worldwide.
About 90 per cent of COPD deaths occur in low- and middle-income countries. In these places diagnostic tests are limited, specialist care is scarce and people often cannot get recommended combination inhalers because they are unavailable or too expensive. Primary healthcare is often overstretched.
Major risk factors include smoking and air pollution, including indoor pollution from cooking with wood or biomass. WHO will issue updated guidelines next year with input from experts in low- and middle-income countries.
