Fortnight 12: 03 June to 16 June 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.

Invasive Meningococcal Disease (IMD)

The number of cases of IMD due to serogroup W (MenW) has been increasing across most jurisdictions in Australia since 2013. The Commonwealth Department of Health, in collaboration with the states and territories, is closely monitoring the incidence of MenW in Australia. For the latest information on IMD, refer to the Department’s website.

Infectious syphilis

Increases in infectious syphilis notifications are attributed to the on-going outbreak occurring in young Aboriginal and Torres Strait Islander people residing in northern Australia.

In January 2011, an increase of infectious syphilis notifications among young Aboriginal and Torres Strait Islander people was identified in the North West region of Queensland, following a steady decline at a national level in remote communities. Subsequent increases in infectious syphilis notifications were reported in the Northern Territory in 2013, Western Australia in 2014 and South Australia in 2016, following sustained periods of low notification rates.

For the latest information on the infectious syphilis outbreak, refer to the Department’s website - Infectious syphilis outbreak.

Mumps

There is an ongoing outbreak of mumps in Indigenous communities in the North West of Queensland. Over 80 cases have been notified from Doomadgee, Mount Isa and Gregory Downs areas, and Mornington Island since the outbreak began at the end of January 2017.


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 19/03/2017 to 16/06/2017.
  2. The quarterly (90 day) five year rolling mean is the average of 5 intervals of 90 days up to 16/06/2017. 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 17/06/2016 to 16/06/2017.
  4. The yearly (365 day) five year rolling mean is the average of 5 intervals of 365 days up to 16/06/2017. 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 03/06/2017 to 16/06/2017

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.
