Epidemiology of COPD
Chronic obstructive pulmonary disease (COPD) is responsible for early mortality, high death rates and significant cost to health systems. Active smoking remains the main risk factor, but other factors are becoming better known, such as occupational factors, infections and the role of air pollution. Prevalence of COPD varies according to the country, age and sex. This disease is also associated with significant comorbidities. COPD is a disorder that includes various phenotypes, the continuum of which remains under debate. The major challenge in the coming years will be to prevent the onset of smoking along with early detection of the disease in the general population.This may represent deterioration in the patient's premorbid condition such that hypoxemia worsens and hypercapnia develops during a relatively trivial respiratory tract infection, which may be viral or bacteria.
