Fortnight 09: 19 April to 02 May 2014

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.

Salmonellosis

Between 19 April and 2 May 2014, there were 692 notifications of salmonellosis compared with 516 during the same period last year. In the last 90 days,1 there were 5,241 notifications, a ratio of 1.4 compared with the quarterly rolling five year mean2 of 3,831 notifications for the same period. These cases were reported from Queensland (262), New South Wales (164), Victoria (100), Western Australia (81), South Australia (43), Northern Territory (19), Australian Capital Territory (16) and Tasmania (7).

Arbovirus (NEC)

Between 19 April and 2 May 2014 there were three notifications of arbovirus NEC in Australia, compared with nine during the previous reporting period and none during the same period of last year.

During the past 90 days, there were 21 notifications, a ratio of 7.0 compared with the quarterly rolling mean of 3.0 notifications.

One notification was for Zika virus infection imported to Queensland from the Cook Islands, one was for Kokobera in Queensland and one was for a Zika virus imported to New South Wales from the Cook Islands.

Measles

There have been 8 cases of measles notified this reporting period from Qld (4), SA (2) and one each from NSW and WA. The number of cases has plateaued at around 5 cases per week from the end of March, a decline from more than 20 cases per week at its peak.

Of the 194 cases notified TD:

  • 41% (n=79) were imported from overseas, with the majority of these cases associated with the Philippines (n=45).
  • Over a third (n=69) were import related, with the majority of these cases linked to cases imported from the Philippines (n=30) and Singapore (n=34).
  • A quarter of cases (n=49) are currently reported as being acquired in Australia with the link to an imported case either unable to be established or currently under investigation.
  • Cases continue to be highest in the 15-19 and 30-34 years age groups, representing over a third of cases. Additionally, 9% of cases (n=18) are aged less than 12 months.

Influenza (laboratory confirmed)

In this reporting period there were 377 confirmed influenza notifications with the majority continuing to be type A (79%). Type B accounted for 21% of notifications, with the remainder reported as either influenza A and B co-infections or untyped. Of the type A cases, 83% were not subtyped, 9% were reported as A(H1N1)pdm09 and 8% were A(H3N2). Around a third of the notifications for this period were from Queensland (131).

Nationally, influenza activity levels are low and stable, but higher than at the same time in previous years. There is no indication that the 2014 influenza season has commenced, nor any indication of the potential severity of the season.

The Australian Government Department of Health continues to monitor influenza activity and will provide a fortnightly summary of influenza activity on the website. The fortnightly Australian Influenza Surveillance Report will commence closer to the onset of the winter influenza season.

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 2 February 2014 to 2 May 2014.
  2. The quarterly (90 day) five year rolling mean is the average of 5 intervals of 90 days up to 2 May 2014. 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 3 May 2013 to 2 May 2014.
  4. The yearly (365 day) five year rolling mean is the average of 5 intervals of 365 days up to 2 May 2014. 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.
