Pneumonia is the leading cause of death due to infectious diseases in the United States ; however, the incidence of most infections causing community-acquired pneumonia in adults is not well defined.
We evaluated all adults, residing in 2 counties in Ohio, who were hospitalized in 1991 because of community-acquired pneumonia.
Information about risk factors, symptoms, and outcome was collected through interview and medical chart review.
Serum samples were collected from consenting individuals during the acute and convalescent phases, and specific etiologic diagnoses were assigned based on results of bacteriologic and immunologic tests.
The incidence of community-acquired pneumonia requiring hospitalization in the study counties in 1991 was 266.8 per 100 000 population ; the overall case-fatality rate was 8.8%. Pneumonia incidence was higher among blacks than whites (337.7/100 000 vs 253.9/100 000 ; P<. 001), was higher among males than females (291.4 vs 244.8 ; P<. 001), and increased with age (91.6/100000 for persons aged<45 years, 277.2/100 000 for persons aged 45-64 years, and 1012.3/100 000 for persons aged =65 years ; P<. 001).
Extrapolation from study incidence data showed the projected annual number of cases of community-acquired pneumonia requiring hospitalization in the United States to be 485 000. (...)
