Respiratory Infections in the Aging Lung: Implications for Diagnosis, Therapy, and Prevention

Abstract

Respiratory infections pose a significant health problem among elderly individuals, particularly during the COVID-19 pandemic. The increased mortality and morbidity rates among individuals over 65 highlight the criticality of these infections. The normal aging process in the lungs increases vulnerability to respiratory infections due to the accumulation of cellular damage and senescence. Consequently, the lung environment undergoes major changes in mechanical function and other systemic factors. This review aims to examine the influence of aging on respiratory infections from a clinical perspective by analyzing clinical studies. Additionally, the review will emphasize potential prevention and diagnostic developments to enhance therapy options available for elderly patients over 65 years of age.
