In 1998 the Communicable Diseases Network Australia New Zealand (CDNANZ) appointed the Hepatitis C Surveillance Committee to develop and implement approaches for improved hepatitis C surveillance in Australia. The Australian Hepatitis C Surveillance Strategy was endorsed in 1999 and provides a framework for improvements to national hepatitis C surveillance. The strategy covers two main surveillance activities: surveillance of incident and prevalent hepatitis C, and the long-term outcomes of hepatitis C. The committee (now the CDNA Viral Hepatitis Surveillance Committee) has continued to facilitate the implementation of the recommendations proposed. Progress towards improvement of hepatitis C surveillance in Australia includes the development of standard case reporting for hepatitis C, collation of data on incident and prevalent hepatitis C from a range of populations at lower and higher risk of hepatitis C, and collation of data from liver transplant registries. Advances in the implementation of the strategy are incremental. While there is enthusiastic commitment towards improving hepatitis C surveillance in Australia, the number of cases, the capacity and competing priorities of State and Territory health departments has meant that implementation has been challenging, highlighting the difficulties in introducing new systems into an already complex situation.</p>","PeriodicalId":520897,"journal":{"name":"Communicable diseases intelligence quarterly report","volume":"26 1","pages":"14-22"},"PeriodicalIF":0.0,"publicationDate":"2002-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144319275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A register of cases that included onset date and time of illness and symptoms was maintained by nursing staff. Faecal specimens were tested for conventional gastrointestinal pathogens and for human calicivirus (HuCV). There were 81 cases reported. Specimens were received for testing from 25 cases. Twenty-three of the 25 (92%) specimens were positive for HuCV RNA by reverse transcriptase polymerase chain reaction (RT-PCR). The 2 negative samples contained RT-PCR inhibitors. Descriptive epidemiology suggested that staffing practices were important in prolonging the outbreak. No point source of infection was identified. Instead environmental contamination, aerosol transmission and work practices that fail to take account of the natural history of HuCV infection probably contributed to the size (81 cases) and duration (3 weeks) of this outbreak among the residents, staff and visitors of an aged-care facility and their contacts. Institutional outbreaks caused by HuCV, formerly called Norwalk-like or small round structured viruses, are extremely difficult to control. Infected staff may contribute significantly to the amplification of outbreaks.

In 2001, however, influenza surveillance remains fragmented in Australia and mainly restricted to major cities. Methods of surveillance and reporting of influenza activity vary between States and even within States. Three disparate case definitions are in use for reporting influenza-like illnesses. Many sentinel sites do not have laboratory support for confirmation of influenza or identification of circulating strains.

Data on surveillance of poliomyelitis, acute flaccid paralysis (AFP), vaccine associated paralytic polio and enteroviruses were provided to document the absence of circulation of wild poliovirus. The last wild poliomyelitis virus case in Australia was in 1972. AFP surveillance has improved since it was initiated in 1995 and achieved a rate of 0.94 per 100,000 population in 1999. No wild polioviruses have been isolated from stool samples of AFP cases. Australia has in place a comprehensive network of laboratories for enterovirus surveillance and this provides further evidence for the absence of wild poliovirus infection. The immunisation coverage in the country has been over 80 per cent over the last 3 years. If there were an importation of a case of poliomyelitis into Australia, a national outbreak response would be coordinated through the Communicable Diseases Network Australia. Plans for containment of laboratory stocks of wild poliovirus are being implemented. The evidence provided was sufficient to satisfy the Regional Commission that there was no wild poliovirus circulating in the region and enabled Australia to be declared polio free on October 29, 2000 along with the other 36 countries in the Western Pacific Region.
