Australia's notifiable diseases status, 2003 annual report of the National Notifiable Diseases Surveillance System.

In 2003, 58 diseases and conditions were notifiable at a national level in Australia. States and territories reported a total of 104,956 cases to the National Notifiable Diseases Surveillance System an increase of 3.2 per cent on the total number of notifications in 2002. In 2003, the most frequently notified diseases were sexually acquired infections (38,854, 37% of total notifications), gastrointestinal diseases (24,655 notifications, 24%) and bloodborne viruses (20,825 notifications, 20%). There were 11,113 notifications of vaccine preventable diseases, 6,780 notifications of vectorborne diseases, 1,826 notification of other bacterial infections and 903 notifications of zoonotic diseases.

Annual report of the National Influenza Surveillance Scheme, 2003.

Surveillance of influenza in Australia is based on laboratory isolation of influenza viruses, sentinel general-practitioner practices for influenza-like illness, and absenteeism data from a major national employer. In 2003, the peak in influenza activity was in August which was later than in 2002. In 2003, 3,604 laboratory-confirmed cases of influenza were notified to the National Notifiable Diseases Surveillance System, which was marginally lower than for the previous year. Ninety-four per cent of the circulating viruses were influenza A. This was the highest proportion in the last five years. Nine hundred and thirty-five isolates were antigenically analysed: 928 were A(H3), two were A(H1) strains and five were influenza B viruses. The majority (98%) of the A(H3) subtypes were A/Fujian/411/2002(H3N2)-like and have shown a significant antigenic drift. The 2003 Australian influenza vaccine contained A/Panama/2007/99, which induced 2-4-fold lower antibody response against the drifted strain. An A/Fujian/411/2002(H3N2)-like virus has been incorporated in the Australian influenza vaccine for 2004. In 2003, the influenza vaccine was given to 77 per cent of Australians aged over 65 years; the same up take as in 2002.

Evaluation of Australia's National Notifiable Disease Surveillance System.

The Australian National Notifiable Diseases Surveillance System (NNDSS) is a passive surveillance system that collects information on communicable diseases. The Australian Government manages NNDSS under the auspices of the Communicable Diseases Network Australia (CDNA). Data collected by each state and territory are collated, analysed and disseminated by the Australian Government Department of Health and Ageing. We report the first evaluation of NNDSS since it was established in 1991. Three primary stakeholder groups were surveyed: (a) CDNA members, (b) the National Surveillance Committee and (c) the readership of Communicable Diseases Intelligence, the primary means of data dissemination from NNDSS. The evaluation revealed that the system was acceptable, structurally simple, and that the data collected were actively used by stakeholders. However, the lack of clearly documented aims and objectives for NNDSS, inflexibility to changing needs, lack of timeliness and complexity in processes were seen as problematic. The results of this evaluation, supported by recent federal funding to enhance national biosecurity, will provide the framework for enhancing NNDSS to meet national communicable disease surveillance requirements in Australia.

Tuberculosis notifications in Australia, 2001.

In 2001, there were 997 cases of tuberculosis (TB) reported to the National Notifiable Diseases Surveillance System, of which, 967 were new cases of TB and 30 cases were relapses. The incidence rate of TB in Australia in 2001 was 5.1 cases per 100,000 population. The highest incidence of TB was reported in people born overseas (19.3 cases per 100,000 population), followed by Indigenous Australians (9.8 cases per 100,000 population). In contrast, the incidence rate of TB in the non-Indigenous Australian-born population was 1.0 cases per 100,000 population. This pattern of TB incidence rates amongst the sub-populations of Australia has been observed for over 10 years. Eighty-six per cent of TB cases completed treatment in 2001. Treatment was unsuccessful in 7 cases and only 22 cases defaulted. The National Tuberculosis Advisory Committee has published a National Strategic Plan with performance indicators to ensure that this enviable record of TB control is maintained and improved.

Norwalk-like virus outbreak in Canberra: implications for infection control in aged care facilities.

This paper reports on an outbreak of viral gastroenteritis in three institutions (two aged care facilities and one hospital) in Canberra during the winter of 2002. Norwalk-like virus genotype II was detected in samples from staff and/or residents in all three institutions. A case series investigation was conducted amongst both staff and residents. It is likely that the outbreaks in the three institutions were linked due to transfers of infected residents from one institution to another, early in the outbreak. A total of 281 cases were identified during the outbreak, which lasted 32 days. Attack rates in the three institutions were 46.3 per cent, 52.7 per cent and 55.2 per cent respectively. Person-to-person spread and/or airborne transmission were postulated as modes of transmission in all three institutions. Infection control practices in each of the aged care institutions were of an acceptable standard for accreditation, but were inadequate to control further spread of the outbreak within and between institutions. Outbreak management plans should be a part of the infection control standards for accreditation of aged care facilities.
