Includes cases with unknown ages.

†     See Results section for case definitions. For diseases not included in Results section, case definitions are listed below. Hospitalisations for rare disease should be interpreted with caution as they may include coding errors.

‡     Haemophilus influenzae type b hospitalisations and deaths not included because there is no ICD-10 code specific to Haemophilus influenzae type b.

§     Rates are per 100,000 population for all ages combined, age-standardised to the Australian Bureau of Statistics Australian population estimates for 2005.

║    Diphtheria: The ICD-10-AM/ICD-10 code A36 (diphtheria) was used to identify hospitalisations and deaths.

**      Pneumococcal disease (invasive): The ICD-10-AM/ICD-10 codes G00.1 (pneumococcal meningitis) and A40.3 (pneumococcal septicaemia) were used to identify hospitalisations due to invasive pneumococcal disease.

††   Poliomyelitis: The ICD-10-AM/ICD-10 code A80 (acute poliomyelitis) was used to identify hospitalisations and deaths. Sequelae of poliomyelitis (ICD-10 code B91) were not included in these analyses. A description of the hospitalisations is included in the 2003–2005 Vaccine Preventable Diseases and Vaccination Coverage report.5

‡‡   Rubella: The ICD-10-AM/ICD-10 code B06 (rubella [German measles]) was used to identify hospitalisations and deaths. Congenital rubella cases were not included in this summary.
