OBJECTIVE:

To review the epidemiology and clinical course of Invasive pneumococcal diseases of infants younger than 60 days.

STUDY DESIGN:

All Streptococcus pneumoniae strains isolated from blood and cerebrospinal fluid cultures of infants below the age of 60 days during the years 1999-2009 were included in this study. Demographic, clinical, and laboratory data were collected from medical records.

RESULTS:

In all, 24 cases of pneumococcal invasive infections were identified. The primary diagnoses were bacteremia without a focus (n = 13), meningitis (n = 6), bacteremia with otitis media (n = 3), and joint infection with bacteremia (n = 2). Only one of the serotypes found is included in the heptavalent pneumococcal conjugated vaccine (PCV7).

CONCLUSIONS:

Streptococcus pneumoniae should be considered and treated empirically in infants with suspected invasive bacterial disease during the first 60 days of life. Routine vaccination with PCV7 in not expected to substantially reduce the incidence of invasive pneumococcal disease in Israeli infants of this age as a result of herd immunity.
