The term pneumonia denotes an infection of the lung parenchyma, as opposed to the bronchi or upper airway. It occurs in patients of all ages, but particularly in the very young and old, and those with compromised immune systems. Pneumonia is an exceptionally common cause of death and hospitalization. Distinct forms occur in patients with different risk factors and in varying settings. Among these, the four most common categories include community acquired pneumonia (CAP), nosocomial pneumonia (i.e., that occurring in a hospital or extended care facility), aspiration pneumonia, and pneumonia in the immunocompromised host. In each category, the risk of pneumonia relates to the virulence of the infecting organisms and the ability of the host to avoid or fight infection. This paper will review the definitions, clinical presentation, and treatment of various forms of pneumonia occurring in adults.
