Syphilis limited to cases of less than 2 years duration, and cases of congenital syphilis.
HIV data includes reports of newly diagnosed HIV infection and cases of HIV infections known to have been newly acquired.
Includes all Hepatitis B and C infections, whether or not the infection was sexually transmitted.
Rates are directly age-standardised to the Australian population as at 30 June 2001.
Computation:
100,000 × (Numerator ÷ Denominator)
Presented as a rate per 100,000.
Age-standardised to the Australian population as at 30 June 2001, using 5-year age groups to 84 years. Indigenous population data are not available for all states and territories for 5-year age groups beyond 64 years, so Indigenous disaggregations are standardised to 64 years.
Calculated separately for each type of infection.
Numerator:
Number of notifications of new cases of syphilis, HIV, Hepatitis B, Hepatitis C, Chlamydia and gonococcal infection

Disaggregation data elements:
Comments:
Specified disaggregation: Nationally and by state/territory: by age group, sex, Indigenous status, remoteness area and SEIFA of residence.
Available disaggregation: Nationally and by state/territory: by age group, sex, Indigenous status, remoteness area and SEIFA of residence.
Data for 2008-09 will be available at the end of 2009.
Most recent data available for 2010 CRC baseline report: 2008.
For data by Indigenous status: ABS Indigenous Experimental Estimates and Projections (Indigenous Population) Series B as at 30 June 2008.
For data by socioeconomic status: calculated using the ABS’ Index of Relative Socioeconomic Disadvantage and Estimated Resident Population (ERP) by Statistical Local Area (SLA) as at 30 June 2008. Each SLA in Australia is ranked and divided into quintiles in a population-based manner, such that each quintile has approximately 20% of the population.
For data by remoteness: ABS ERP as at 30 June 2008, by remoteness areas, as specified in the Australian Standard Geographical Classification (ASGC).
Specification: Long-term
Improvement in the quality of Indigenous identification in notification data in the National Notifiable Diseases Surveillance System (NNDSS).
Other issues caveats:
Disaggregation by Indigenous status, remoteness area and SEIFA of residence within individual states/territories is subject to data quality considerations.
Some disaggregations could result in numbers too small for publication.
The capacity remains to add additional sexually transmitted infections and blood-borne viruses as public health priorities change.
