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.

Multijurisdictional outbreak investigation: Listeriosis

OzFoodNet continues to investigate this outbreak. As of 8 March 2013, there were 29 confirmed listeriosis cases from six jurisdictions. Three people have died and one miscarriage was associated with this outbreak. There were seven new notified cases of listeriosis identified during the past fortnight. All are pending further laboratory investigation to determine if they are associated with the current outbreak.

Evidence gathered from the epidemiological investigation, case histories, laboratory testing, food sampling and traceback information has identified a link between outbreak cases and the consumption of soft cheese. The manufacturer conducted a voluntary recall of a particular batch as a precautionary measure on 18 December 2012. A second recall occurred on 18 January 2013 included all cheeses manufactured on or before 6 January 2013. Investigations are ongoing to identify any further cases and the environmental source of contamination in this outbreak.

Gonococcal infection


This reporting period there were 488 notifications of gonococcal infection reported to the NNDSS. The cases were mostly notified from New South Wales (198), Queensland (117) and Western Australia (91). Over the past quarter1 there have been 3,351 notifications, which is 1.4 times the quarterly rolling five year mean2 for the same period. In the past twelve months there have been 14,011 notifications which is 1.5 times the yearly rolling 5 year mean4. Gonococcal infection notifications continue to present an upward trend, with some jurisdictions noting higher than expected numbers.

Analysis of the male to female incidence ratio suggests that in general transmission of gonorrhoea in the non-Indigenous population is predominately among men who have sex with men, whereas in the Indigenous population transmission is predominately through heterosexual contact.

Typhoid fever

There were nine notified cases of typhoid infection reported between 23 February and 8 March 2013. Over the past quarter there have been 64 notified cases, which is 1.7 times the quarterly rolling five year mean2 of 38 cases.

Typically, most infections are acquired overseas, mostly in South and South East Asia. Australians planning travel to at-risk destinations should consult their doctor prior to travel. Your doctor can provide advice on ways to prevent infection. Further information is available from Smartraveller website.

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.Top of page

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.

1The past quarter (90 day) surveillance period includes the date range 09/12/2012 to 08/03/2013.
2The quarterly (90 day) five year rolling mean is the average of 5 intervals of 90 days up to 8 March. The ratio is the notification activity in the past quarter (90 days) compared with the five year rolling mean for the same period.
3The past year (365 day) surveillance period includes the date range 09/03/2012 to 08/03/2013.
4The yearly (365 day) five year rolling mean is the average of 5 intervals of 365 days up to 8 March. 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.
