Fortnight 04: 08 February to 21 February 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.

Measles

There have been 31 cases of measles reported this reporting period from NT (16), NSW (7), WA (4), Vic (2), Qld (1) and SA (1). The median age is 25, the age range is from 0-62.

Of the 116 cases notified YTD:

  • Almost 60% of cases were either imported from overseas or were import-related, with the majority of these cases related to the Philippines;
  • Some of the import-related cases (n=10) have been linked to a multijurisdictional outbreak associated with an imported case from the Philippines who attended a dance competition in Sydney in early December 2013; and
  • Of the remaining 42% of cases reported as locally acquired, information about their source of infection has either not been established or is still under investigation.

Q fever

During the reporting period there were 15 notifications of Q fever reported to the NNDSS, compared to 23 in the previous reporting period and 21 in the same reporting period last year. During the past 90 days, there were 129 notifications, a ratio of 1.5 compared with the quarterly rolling mean of 86 notifications. The cases for the current reporting period were notified by Qld (8), NSW (4), Vic (2) and NT (1). No point source of infection is involved, and there is no clustering of risk factors.


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 24 November 2013 to 21 February 2014.
  2. The quarterly (90 day) five year rolling mean is the average of 5 intervals of 90 days up to 21 February 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 22 February 2013 to 21 February 2014.
  4. The yearly (365 day) five year rolling mean is the average of 5 intervals of 365 days up to 21 February 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.
