Fortnight 13: 14 June to 27 June 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 were 13 cases notified in this reporting period including WA (7), Qld (3), NSW (1), NT (1) and Vic (1). This includes a cluster of five cases currently under investigation in WA.

    Of the 242 cases notified year to date:

    • The majority were either imported from overseas 39% (n=95) or import related 30% (n=72). These cases were associated with travel to the Philippines, Singapore and more recently Papua New Guinea.
    • Although 30% of cases were reported as being acquired in Australia with the link to an imported case either not established or currently under investigation, it is likely these are all import related.
    • Cases continue to be highest in the 15-19 and 30-34 years age groups, representing over a third of cases. Additionally, 9% of cases (n=21) were less than 12 months of age.
    • Of those cases aged over 12 months (n=221) and eligible for vaccination, 40% (n=89) were reported as not vaccinated and a further 40% (n=89) had an unknown vaccination status. The remaining 19% of cases (n=43) were reported as being vaccinated, of which 36 had received one dose and seven had received two doses of a measles containing vaccine.
    • Vaccination is the best protection against measles. All travellers should ensure that they are up to date with routinely recommended vaccinations including measles prior to travel. More information is available on vaccination from the National Immunisation Programme.

    Influenza (laboratory confirmed)

    In this reporting period there were 986 confirmed influenza notifications with the majority continuing to be type A (87%). Type B accounted for 12% of notifications, with the remainder reported as either influenza A and B co-infections or untyped. Of the type A cases, 76% were not subtyped, 16% were reported as A(H1N1)pdm09 and 8% were A(H3N2). Approximately 31% of the notifications for this period were from Queensland (303).

    Nationally influenza activity has started to increase in Victoria, New South Wales, South Australia and Tasmania, although overall activity remains relatively low. As yet, there is no 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.

    Salmonellosis

    CDNA is monitoring an increase in salmonellosis notifications during the first half of 2014. Between 14 and 27 June 2014, there were 509 notifications of salmonellosis compared with 380 during the same period last year. In the past quarter, there were 4,452 notifications, a ratio of 1.6 compared with the quarterly rolling five year mean of 2,795.

    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 30 March 2014 to 27 June 2014.
    2. The quarterly (90 day) five year rolling mean is the average of 5 intervals of 90 days up to 27 June 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 28 June 2013 to 27 June 2014.
    4. The yearly (365 day) five year rolling mean is the average of 5 intervals of 365 days up to 27 June 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.
