Invasive Pneumococcal (Streptococcus pneumoniae) Disease or IPD causes many clinical syndromes,
depending on the site of infection (e.g., bacteremia, meningitis.)
Laboratory Criteria for Diagnosis
Supportive: Identification of S. pneumonia from a normally sterile
body site by a culture-independent diagnosis test
(CIDT) without isolation of the bacteria.
Confirmatory: Isolation of S. pneumonia from a normally sterile
body site.
Epidemiologic Linkage
Not required.
Criteria to Distinguish a New Case from an Existing Case
A single case should be defined as a health event with a specimen collection date that occurs
more than 30 days from the last known specimen with a positive lab finding.
