Chronic obstructive pulmonary disease (COPD) is a progressive lung disease characterized by persistent airflow limitation that is not fully reversible. It primarily affects the lungs’ airflow and lung function, leading to breathing difficulties. COPD encompasses emphysema and chronic bronchitis and is a significant public health concern due to its high prevalence and impact on mortality and healthcare resources. According to the Centers for Disease Control and Prevention (CDC), as of 2018, COPD is identified as the fourth leading cause of death in the United States, underscoring its grave health implications (CDC, 2021). The disease also imposes a substantial burden on the healthcare system, with approximately 15.4 million physician visits, 1.5 million emergency department visits, and over 726,000 hospital visits annually related to COPD (May & Li, 2015).

The prevalence of COPD has been steadily rising, partly due to historical rates of smoking and exposure to environmental pollutants. It is estimated that around 16 million people in the U.S. have been diagnosed with COPD, though the actual number may be higher since many cases remain undiagnosed due to the insidious onset of symptoms. Epidemiological studies suggest that the prevalence of COPD varies with age, smoking status, and socioeconomic factors; older adults and current or former smokers are at significantly greater risk.

Globally, the World Health Organization (WHO) estimates that COPD affects over 200 million people worldwide, and in the United States, an estimated 14 million cases have been reported as of recent data (WHO, 2022). The disease’s burden is expected to grow further due to increasing exposure to risk factors such as tobacco smoke, occupational dust, chemicals, and air pollution. Countries with high smoking rates tend to report higher COPD prevalence, reflecting the cumulative impact of smoking on lung health over time.

Quantitative assessments of affected populations highlight that COPD is a major contributor to morbidity, diminished quality of life, and premature mortality. The economic burden associated with COPD includes direct medical costs, such as hospitalization and medication, as well as indirect costs related to lost productivity and disability. According to a study by CDC (2021), the cost burden of COPD in terms of healthcare utilization in the United States runs into billions of dollars annually. Moreover, as the population ages, there is a projected increase in the prevalence and associated economic costs, emphasizing the importance of effective prevention, early detection, and management strategies.

Preventative measures such as smoking cessation programs, reducing exposure to occupational and environmental pollutants, and vaccination against respiratory infections can significantly decrease the risk of developing COPD or mitigate its progression. Also, public health initiatives aim to improve awareness, screening, and access to healthcare services to better manage the disease at an early stage, ultimately reducing its impact on individuals and society.
