Summary
Pneumococcal bacteremia affected 18.8 per 100,000 people annually, with higher risks for the very young, elderly, and Black populations. Immunization is suggested for Black individuals over 55.
Area of Science:
- Epidemiology
- Infectious Diseases
- Public Health
Background:
- Pneumococcal disease epidemiology is vital for public health.
- Understanding disease patterns informs prevention and immunization strategies.
Purpose of the Study:
- To determine the incidence and case-fatality rates of pneumococcal bacteremia.
- To identify high-risk populations for pneumococcal infection.
Main Methods:
- Retrospective review of laboratory and clinical records.
- Study conducted in Monroe County, New York (1985-1989).
- Pneumococcal bacteremia used as a proxy for pneumococcal disease.
Main Results:
- 671 cases identified, with an overall annual rate of 18.8 per 100,000.
- Highest incidence rates observed in the very young, elderly, and non-White populations.
- Case-fatality rates were 15% overall, increasing with predisposing conditions and age, particularly in Black populations.
Conclusions:
- Pneumococcal bacteremia incidence and mortality were documented.
- Black populations face an elevated risk of invasive pneumococcal infection.
- Immunization consideration is recommended for Black individuals over 55 years old.
