Epidemiology of community- and nursing home-acquired pneumonia in older adults

Expert Rev Anti Infect Ther. 2005 Apr;3(2):263-70. doi: 10.1586/14787210.3.2.263.


Pneumococcus remains the most important cause of community-acquired pneumonia in older adults. Alcoholism, bronchial asthma, immunosuppression, lung disease, heart disease, institutionalization and increasing age are important risk factors. There is a reduced prevalence of nonrespiratory symptoms in this age group. Advanced age and comorbidity are important prognostic factors. Influenza and pneumococcal vaccination remain the key factors for prevention.
