Date of last revision/review: May 2008
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)
Clinical evidence of invasive disease (see section below) with laboratory confirmation of infection:
- isolation of H. influenzae (serotypes a, c, d, e, f, undifferentiated and non-typeable isolates) from a normally sterile site
- isolation of H. influenzae (serotypes a, c, d, e, f, undifferentiated and non-typeable isolates) from the epiglottis in a person with epiglottitis
Clinical illness associated with invasive disease due to H. influenzae includes meningitis, bacteremia, epiglottitis, pneumonia, pericarditis, septic arthritis and empyema.
