Fortnight 10: 03 May to 16 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.

Influenza (laboratory confirmed)

In this reporting period there were 556 confirmed influenza notifications with the majority continuing to be type A (80%). Type B accounted for 20% of notifications, with the remainder reported as either influenza A and B co-infections or untyped. Of the type A cases, 87% were not subtyped, 10% were reported as A(H1N1)pdm09 and 3% were A(H3N2). Approximately 40% of the notifications for this period were from Queensland (223).

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.

Infant botulism (Clostridium botulinum)

QLD Health has reported a case of infant botulism in a 5 month old female.

The infant was hospitalised with Acute Flaccid Paralysis in April 2014 and subsequently was diagnosed with botulism. She was administered Baby BIG and her condition is improving.

C. botulinum toxin B gene was detected by PCR in a faecal specimen and confirmed as Toxin type B by mouse bioassay. It was reported that the infant had not consumed any honey.

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 16 February 2014 to 16 May 2014.
  2. The quarterly (90 day) five year rolling mean is the average of 5 intervals of 90 days up to 16 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 17 May 2013 to 16 May 2014.
  4. The yearly (365 day) five year rolling mean is the average of 5 intervals of 365 days up to 16 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.
