Influenza (laboratory confirmed)
- Across all jurisdictions, seasonal influenza activity has continued to decline following recent peaks in activity. In South Australia, where activity has plateaued for several weeks, there has been a decline in the most recent week.
- Nationally influenza A is the predominant influenza virus type. Influenza A(H1N1)pdm09 continues to be the dominant circulating virus subtype in the Northern Territory, South Australia, Tasmania and Victoria while in New South Wales and the Australian Capital Territory*, influenza A(H3N2) is the most common virus type. The proportion of influenza A(H3N2) has increased in recent weeks in Queensland and Western Australia where both strains now co-circulate in similar proportions. The usual, late season increase in influenza B infections has also been noted in recent weeks.
- 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 was noted in NSW, where influenza A(H3N2) circulated at higher levels and affected people in older age-groups, which has led to a substantial number of outbreaks in aged care facilities.
- The WHO released its recommendations for the composition of the 2015 southern hemisphere influenza season vaccine which includes changes to the A(H3N2) and B vaccine strains.

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.
- The past quarter (90 day) surveillance period includes the date range 06/07/2014 to 03/10/2014.
- The quarterly (90 day) five year rolling mean is the average of 5 intervals of 90 days up to 03/102014. The ratio is the notification activity in the past quarter (90 days) compared with the five year rolling mean for the same period.
- The past year (365 day) surveillance period includes the date range 04/10/2013 to 03/10/2014.
- The yearly (365 day) five year rolling mean is the average of 5 intervals of 365 days up to 03/10/2014. 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.
