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.

Diphtheria

Diphtheria is rare in Australia, with most cases associated with sporadic importations from countries in which the disease remains endemic. From 1991 to 2016 year-to-date (YTD), there have been a total of 18 cases of diphtheria reported to the National Notifiable Diseases Surveillance System (NNDSS), including a cluster of 3 cases and a sporadic case in 2011.

Over the last fortnight, there has been 1 case of cutaneous diphtheria notified to the NNDSS. This case was reported from Queensland and was acquired in Papua New Guinea. So far, in 2016 there have been 6 cases of diphtheria notified; which were all acquired overseas.

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.

Leprosy

In the 2016 YTD there have been 18 notifications of leprosy reported to the NNDSS. Two-thirds of these notifications were reported to have acquired their infection overseas (67%) and 22% in Australia. No further information regarding place of acquisition was available for the remainder of cases (11%). Over a quarter (28%) of cases notified to the NNDSS in 2016 YTD were reported in individuals of Aboriginal and Torres Strait Islander background. Between 2006 and 2015, the mean annual number of notifications of leprosy was 10.1 (range 6-14). Whilst there has been a slightly increasing trend in the number of leprosy notifications in recent years, the majority of notifications are acquired overseas, with a very small number of locally acquired cases occurring among Aboriginal and Torres Strait Islander people.


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 04/09/2016 to 02/12/2016.
  2. The quarterly (90 day) five year rolling mean is the average of 5 intervals of 90 days up to 02/12/2016. 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 04/12/2015 to 02/12/2016.
  4. The yearly (365 day) five year rolling mean is the average of 5 intervals of 365 days up to 02/12/2016. 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.
