Fortnight 02: 14 January to 27 January 2017

The Communicable Diseases Network Australia 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 is currently at inter-seasonal levels in Australia. Influenza-like illness presentations to sentinel general practitioners remains within the expected range for this time of year. However, notifications of laboratory-confirmed influenza were three times higher in the last quarter of 2016 (n=9,687) when compared to the quarterly rolling 5 year mean (n=3,275). This is due to Queensland, South Australia and Victoria reporting higher than expected inter-seasonal activity towards the end of 2016.

For the calendar year to date, 86% of notifications of laboratory confirmed influenza to the NNDSS were influenza A (75% A(unsubtyped), 1% influenza A(H1N1)pdm09 and 10% influenza A(H3N2), 13% were influenza B and less than 1% were influenza A&B co-infections or untyped. The dominance of influenza A(H3N2) is consistent with current activity in the northern hemisphere.


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 30/10/2016 to 27/01/2017.
  2. The quarterly (90 day) five year rolling mean is the average of 5 intervals of 90 days up to 27/01/2017. 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 29/01/2016 to 27/01/2017.
  4. The yearly (365 day) five year rolling mean is the average of 5 intervals of 365 days up to 27/01/2017. 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.

A copy of the table of communicable disease notifications for this fortnight is also included in the PDF printable version of the NNDSS report.

Notifications of Nationally Notifiable Diseases for the period 14/01/2017 to 27/01/2017

Footnotes:

* Ratio of the 90 day prior surveillance period to the past 90 day 5 year rolling mean, or ratio of the 365 day prior surveillance period to the 365 day 5 year rolling mean.

NN = Not Notifiable, NEC = Not Elsewhere Classified

The data in this report is reliant on the surveillance data provided from by states and territories to the Department of Health. Delays in the reporting of data may cause retrospective revision causing discrepancies between the number of new notifications and the increment in the cumulative figures from the previous period. Please note that Victoria is currently experiencing an administrative backlog in the entry of notifications, this has affected the availability of notification data for the following diseases: Gonoccocal infection, Varicella and Campylobacteriosis.
