Slowing Progression of Airway Diseases by Smoking Cessation and Reducing Infections

Abstract

The prevalence of respiratory diseases, including asthma and chronic obstructive pulmonary disease, has increased in recent decades, placing a significant burden on healthcare systems and economies around the world. As these diseases are largely incurable, the aim of treatment is to control symptoms and improve quality of life. Aside from stopping smoking and reducing biomass fuel exposure, arguably the most effective strategy in the long-term management of chronic respiratory diseases is the prevention or control of respiratory infections via vaccines and antimicrobial agents. By preventing these infections or reducing exposure to some of the major risk factors, we can reduce further lung damage in these patients, thereby slowing disease progression. This review looks at maintaining long-term respiratory health in patients with asthma and chronic obstructive pulmonary disease, primarily through smoking cessation, reducing exposure to allergens and air pollutants, and infection control.
