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. WA: genital only.
6. NT, Qld, SA, Vic and WA: includes gonococcal neonatal ophthalmia.
7. Includes congenital syphilis.
8. Includes congenital rubella
# Date of notification = a composite of three components: (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.
NEC Not Elsewhere Classified.
- Elsewhere Classified.
n/a Not calculated as only notifiable under 5 years.
NDR No data received. Only notifiable from January 2001. Data are not yet available.
* Ratio = ratio to current month total to mean of last 5 years calculated as described above.
‡ Sexually transmitted infections data is currently under review in Victoria, therefore notifications of chlamydia and syphilis for the 1st quarter of 2001 should be interpreted with caution.
