In 2012, the most frequently notified diseases were sexually transmissible infections (99,250 notifications, 40.7% of total notifications), vaccine preventable diseases (85,810 notifications, 35.2% of total notifications), and gastrointestinal diseases (31,155 notifications, 12.8% of total notifications) (Table 3).

There was an overall increase of 2% in notifications nationally compared with the total number of notifications in 2011 (Figure 2).

Notifications and notification rates per 100,000 for each disease notified to each state and territory in 2012, are shown in Table 4 and Table 5, respectively. Notifications and rates per 100,000 for the period 2007 to 2012 are shown in Table 6.

* Newly acquired hepatitis and syphilis includes cases where the infection was determined to be acquired within 24 months prior to diagnosis. Queensland reports hepatitis C newly acquired under hepatitis C unspecified.

† Unspecified hepatitis and syphilis includes cases where the duration of infection could not be determined or is greater than 24 months.

‡ In Queensland, includes newly acquired hepatitis C cases.

§ Infection with Shiga toxin/verotoxin producing Escherichia coli.

|| Includes identified from cervical, rectal, urine, urethral, throat and eye samples, except for South Australia, which reports only cervical, urine and urethral specimens; the Northern Territory and Western Australia exclude ocular infections.

¶ The national case definitions for chlamydial, gonococcal and syphilis diagnoses, include infections that may be acquired through a non-sexual mode (especially in children – e.g. perinatal infections, epidemic gonococcal conjunctivitis).

** Does not include congenital syphilis.

†† Data for all states and territories are reported by diagnosis date, except Queensland which is reported by notification receive date.

‡‡ In the Australian Capital Territory, Murray Valley encephalitis virus infection and Kunjin virus infection are combined under Murray Valley encephalitis virus infection.

§§ Only invasive meningococcal disease is nationally notifiable. However the Australian Capital Territory also reports conjunctival cases.

NEC Not elsewhere classified.

Indigenous status

Indigenous status was complete for 51.5% of notifications, and varied by jurisdiction. Indigenous status was complete for 94.7% of data reported in the Northern Territory, 93% in Western Australia and 91.5% in South Australia. In the remaining jurisdictions, Indigenous status completeness ranged from 16.8%–50.1% (Table 9).

Table 9: Indigenous status completeness of National Notifiable Diseases Surveillance System data, Australia, 2012, by state or territory*
  State or territory Aust.
ACT NSW NT Qld SA Tas. Vic. WA
* Indigenous status is usually obtained from medical notification and completeness varies by disease and by state and territory. This reflects differences in notification requirements (i.e. depending on the jurisdiction, some diseases are primarily or completely notified by pathology laboratories rather than clinicians) and the fact that it is not possible to follow up all cases for diseases with a large volume of notifications and/or not requiring specific case based public health action.

Data completeness on Indigenous status also varied by disease as summarised in Appendix 3. There were 7 diseases for which notifications were 100% complete for Indigenous status. A further 25 diseases equalled or exceeded 80% completeness for Indigenous status.

In 2012, CDNA set target thresholds of 95% completeness for 18 priority diseases (Table 10) and 80% completeness for the remainder of the notifiable diseases. In 2012, there were 8 priority diseases for which Indigenous status completeness exceeded 95% (donovanosis, Haemophilus influenzae type b, hepatitis A, measles, meningococcal infection, syphilis < 2 years duration, leprosy, and tuberculosis).
