National Notifiable Diseases Surveillance System - current CDNA fortnightly report

The Communicable Diseases Network Australia (CDNA) holds fortnightly teleconferences to share and evaluate the latest information and developments in communicable diseases surveillance. This report provides a fortnightly summary on diseases of current interest and notifications of Australia's nationally notifiable diseases.

Flavivirus infection (unspecified)

Zika virus infection is notified under flavivirus unspecified. For the latest information on Zika virus infection, including the number of imported cases reported in Australia and the countries known to have ongoing transmission refer to the Department’s website.

Influenza (laboratory confirmed)

Influenza activity remains at low levels across Australia. The Australian Government Department of Health continues to monitor influenza activity and has commenced publication of a detailed analysis of influenza activity on the Department's website.

Shigellosis

Over the last 3 months there have been 351 notifications for shigellosis which is 2.2 times the 5 year quarterly mean of 156.2. Of these, 36% (127/351) were classified as probable infections by some jurisdictions because for infections diagnosed by multiplex PCR only, it is not possible to distinguish between Shigella species and enteroinvasive Escherichia coli. Another 41% (145/351) are Shigella sonnei biotype G, which is at its highest levels since late 2014. NSW Health reported an outbreak of shigellosis in gay men in NSW on 15 July 2016 (www.health.nsw.gov.au/Infectious/alerts/Documents/2016/Shigellosis-Clinician-alert-15July2016.pdf) OzFoodNet epidemiologists from other jurisdictions have also reported several cases in gay men.


Interpretative Notes

Selected diseases are chosen each fortnight based on either exceeding two standard deviations from the 90 day and/or 365 day five year rolling mean or other disease issues of significance identified during the reporting period. All diseases reported are analysed by notification receive date. Data are extracted each Monday of a CDNA week.

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.

  1. The past quarter (90 day) surveillance period includes the date range 17/04/2016 to 15/07/2016.
  2. The quarterly (90 day) five year rolling mean is the average of 5 intervals of 90 days up to 15/07/2016. The ratio is the notification activity in the past quarter (90 days) compared with the five year rolling mean for the same period.
  3. The past year (365 day) surveillance period includes the date range 17/07/2015 to 15/07/2016.
  4. The yearly (365 day) five year rolling mean is the average of 5 intervals of 365 days up to 15/07/2016. The ratio is the notification activity in the past year (365 days) compared with the five year rolling mean for the same period.

The five year rolling mean and the ratio of notifications compared with the five year rolling mean should be interpreted with caution. Changes in surveillance practice, diagnostic techniques and reporting may contribute to increases or decreases in the total notifications received over a five year period. Ratios are to be taken as a crude measure of current disease activity and may reflect changes in reporting rather than changes in disease activity.
