National case definition: Invasive Pneumococcal Disease

Invasive pneumococcal disease

Date of last revision/review: May 2008

National notification

Only confirmed cases of disease should be notified.

Type of surveillance

Routine case-by-case notification to the federal level

Enhanced case-by-case notification to International Circumpolar Surveillance in participating Northern regions

Enhanced active case-by-case notification by paediatric tertiary care hospitals involved in the Immunization Monitoring Program, Active (IMPACT)

Case classification

Laboratory comments

Sputum and bronchial lavages are not considered sterile specimens.

Demonstration of S. pneumoniae DNA or antigen does not permit determination of serotype. Serotyping is carried out in a reference laboratory and is important for monitoring changes in disease epidemiology, including the impact of vaccination programs and serotype replacement.

Clinical Evidence

Clinical illness associated with invasive disease manifests itself mainly as pneumonia with bacteremia, bacteremia without a known site of infection, and meningitis. Pneumonia without bacteremia is not notifiable.

ICD code(s)

Comments

Probable case definitions are provided as guidelines to assist with case finding and public health management, and are not for national notification purposes.
