Invasive Pneumococcal Disease

[Previous][Table of Contents][Next]

Nationally notifiable since 2000

1.0 National Notification

Only confirmed cases of disease should be notified.

2.0 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)

3.0 Case Classification

3.1 Confirmed case

Clinical evidence of invasive disease (see section 5.0) with laboratory confirmation of infection:

• isolation of Streptococcus pneumoniae from a normally sterile site (excluding the middle ear and pleural cavity)
  OR
• demonstration of S. pneumoniae DNA from a normally sterile site (excluding the middle ear and pleural cavity)

3.2 Probable case

Clinical evidence of invasive disease with no other apparent cause and with nonconfirmatory laboratory evidence:

• demonstration of S. pneumoniae antigen from a normally sterile site (excluding the middle ear and pleural cavity)

4.0 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.

5.0 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.
