Severe CAP frequently develops in individuals with comorbid factors such as underlying cardiopulmonary disease, diminished splenic function, and/or heightened pathogenic virulence. Even in young and/or healthy hosts, severe CAP can develop if the causative pathogen is sufficiently virulent. For example, influenza, severe acute respiratory syndrome (SARS), Hantavirus pulmonary syndrome (HPS), and Legionnaires disease may present as severe CAP. [26, 27, 28, 29]

Patients with severe CAP should have the benefit of an infectious disease specialist to assist in identifying and optimally managing the underlying cause.
