Fortnight 19: 06 September to 19 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.

Fortnight 19: 06 September 2014 to 19 September 2014

Influenza (laboratory confirmed)

  • Across almost all jurisdictions, seasonal influenza activity appears to have peaked in recent weeks with the exception of South Australia where activity has been plateauing.
  • 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.

A comprehensive analysis of influenza surveillance data is available in the Australian Influenza Surveillance Report, which is published fortnightly on the Department of Health website.

Kunjin virus infection

Between 6 and 19 September 2014, there were two notifications of Kunjin virus (KUNV) infection, the first cases in the year-to-date. One of these was reported to have been acquired in the Indonesia, and the other in East Africa. Please note: Queensland Health is following up on the details of the case reported to have been acquired in East Africa as a KUNV infection acquired in Africa is unexpected.

Japanese encephalitis virus infection

Between 6 and 19 September 2014, there was one notification of Japanese encephalitis virus infection, the first notification in the year-to-date. The case was reported to have been acquired in Indonesia.

Interpretative Notes

* These subtyped ACT influenza cases have been reported as A(H3). Based on nationally available subtyping and charaterisation data, these cases are assumed to be A(H3N2).

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