Fortnight 18: 23 August to 05 September 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)

  • Across most jurisdictions, seasonal influenza activity appears to have peaked in recent weeks with the exception of South Australia and the Northern Territory where activity continues to rise.
  • Nationally influenza A is the predominant influenza virus type. Of those viruses where subtyping data are available, A(H1N1)pdm09 remains the predominant influenza virus type in most jurisdictions. In New South Wales and the Australian Capital Territory, influenza A(H3N2) is the most common virus type.
  • The influenza vaccine is likely to provide good coverage against the currently circulating viruses.
  • The severity of the 2014 influenza season appears to be moderate across most jurisdictions. However, more severe activity is noted in NSW, where influenza A(H3N2) is circulating at higher levels and affecting people in older age-groups, which has led to a substantial number of outbreaks in aged care facilities.

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 08/06/2014 to 05/09/2014.
  2. The quarterly (90 day) five year rolling mean is the average of 5 intervals of 90 days up to 05/09/2014. 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 06/09/2013 to 05/09/2014.
  4. The yearly (365 day) five year rolling mean is the average of 5 intervals of 365 days up to 05/09/2014. 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.
