Pathophysiologically, the organism's thick polysaccharide capsule impairs phagocytosis, frequently leading to severe necrotizing inflammation, microabscess formation, lung cavitation, and characteristic production of thick, blood-tinged "currant jelly" sputum

Clinically, it manifests with high fevers, productive cough, pleuritic chest pain, and dyspnea, carrying a substantial risk of rapid progression to bacteremia, respiratory failure, and sepsis
