Annual report National Notifiable Diseases Surveillance System, 2004 Pertussis Pertussis continues to be the most common vaccine preventable illness in Australia, with periodic epidemics occurring at intervals of 3 to 5 years on a background of endemic circulation (Figure 44). In 2004, there were 8,557 cases (42.5 cases per 100,000 population) notifi ed to NNDSS. Of these, 7,638 were confi rmed and 649 were probable cases, while the status of the remaining 270 cases was unknown. Figure 44. Notifications of pertussis, Australia, 1996 to 2004, by month of onset Notifications Case defi nition – Pertussis Both confirmed cases and probable cases are notifi ed. Confirmed case: Requires isolation of Bordetella pertussis or detection of B. pertussis by nucleic acid testing OR seroconversion or significant increase in antibody level or fourfold or greater rise in titre (in the absence of pertussis vaccination) or a single high-titre IgA to whole cells or detection of B. pertussis by immunofl uorescence AND clinical evidence (a coughing illness lasting 2 weeks or more or paroxysms of coughing or inspiratory whoop or post-tussive vomiting) OR clinical evidence AND epidemiological link to a confi rmed case. Probable case: Requires clinically compatible illness. 1,800 1,600 1,400 1,200 1,000 800 600 400 200 The highest notification rates were among children aged
National Notifiable Diseases Surveillance System, 2004 Annual report Map 6. Notification rates of pertussis, Australia, 2004, by Statistical Division of residence Figure 46. Notification rates of pertussis, New South Wales, South Australia, Western Australia and Australia, 1999 to 2004, by month of notification A review of cough symptoms in children in Sydney has provided evidence of cases of pertussis which are not notifi ed. Clinically diagnosed pertussis was estimated to be between 5 and 20 times the notifi cation rates. 17 Rate per 100,000 population 350 300 250 200 150 100 50 0 Jan Jul 1999 New South Wales South Australia Western Australia Australia Jan 2000 Jul Jan 2001 Jul Jan 2002 Jul Month and year Jan 2003 Jul Jan 2004 Jul Invasive pneumococcal disease Case defi nition – Invasive pneumococcal disease Only confirmed cases are notifi ed. Confirmed case: Requires isolation of Streptococcus pneumoniae from a normally sterile site by culture or detection by nucleic acid testing. There were 153 cases who were identified as Indigenous (31.6 cases per 100,000 population) and 8,227 who were identified as non-Indigenous (41.9 cases per 100,000 population). The Indigenous pertussis notification rate ratio for all ages was therefore 0.75, but it is important to note that previous analyses have shown that, in the age groups where the disease is most severe, there were higher rates in Indigenous compared to non-Indigenous populations. For example, in 2000–2002 the notification rate ratio for children aged 0–4 years was 1.7, and 2.6 for those aged less than one year. 12 There were 2,375 notifi cations of invasive pneumococcal disease (IPD) in Australia in 2004 giving a rate of 11.8 cases per 100,000 population. While the largest number of cases were reported from New South Wales, Queensland and Victoria (Table 1), the highest rate was in the Northern Territory (47 cases per 100,000 population). The geographical distribution of IPD varied within states and territories, with the highest rates in Central and northern Australia. CDI Vol 30 No 1 2006 51
