There were 20,278 notifications to the National Notifiable Diseases Surveillance System (NNDSS) with a notification date between 1 April and 30 June 2001 (Table 2). Figure 1 illustrates, for selected Diseases, the 2nd quarter 2001 totals as ratios to the mean of the 2nd quarters for the previous 5 years. A summary of Diseases currently being reported by each jurisdiction is provided in Table 1. The notification rate of Diseases per 100,000 population for each State or Territory is presented in Table 3.

1. Totals comprise data from all States and Territories. Cumulative figures are subject to retrospective revision so there may be discrepancies between the number of new notifications and the increment in the cumulative figure from the previous period.
2. Unspecified numbers should be interpreted with some caution as the magnitude may be a reflection of the numbers of tests being carried out.
3. Not reported for NSW because it is only notifiable as 'foodborne disease' or 'gastroenteritis in an institution'.
4. Infections with Shiga-like toxin (verotoxin) producing E. coli (SLTEC/VTEC).
5. NT, Qld, SA, Vic and WA: includes gonococcal neonatal ophthalmia.
NA Not calculated as only notifiable for under 5 years.
6. Includes congenital syphilis.
7. Includes congenital rubella
* Date of notification = a composite of three dates: (i) the true onset date from a clinician, if available, (ii) the date the laboratory test was ordered, or (iii) the date reported to the public health unit.
† Ratio = ratio of current month total to mean of last 5 years calculated as described above.
NDR No data received.
NN. Not Notifiable
NEC Not Elsewhere Classified.

The NNDSS is conducted under the auspices of the Communicable Diseases Network Australia. The system coordinates the national surveillance of more than 50 communicable diseases or disease groups endorsed by the Communicable Diseases Network Australia and the National Public Health Partnership. Notifications of these diseases are made to State and Territory health authorities under the provisions of their respective public health legislation. De-identified core unit data are supplied fortnightly for collation, analysis and dissemination. For further information, see Commun Dis Intell 2000;24:6-7.
