Which age group is particularly vulnerable to developing pneumonia?

The elderly population is particularly vulnerable to developing pneumonia due to several factors. As individuals age, their immune systems tend to become less effective, which makes it harder for them to fight off infections, including those that lead to pneumonia. Additionally, older adults often have comorbid conditions, such as chronic obstructive pulmonary disease (COPD), heart disease, and diabetes, which can further compromise their respiratory health and overall immunity.

Furthermore, physiological changes associated with aging, such as diminished lung function and impaired cough reflex, can contribute to an increased risk of respiratory infections. In older adults, the cilia in the respiratory tract may be less effective at clearing secretions, providing a more conducive environment for pathogens to thrive.

While children under five years are also at risk due to their developing immune systems, the elderly face a higher degree of vulnerability because of the cumulative effects of aging and associated chronic health issues.
