The monitoring of human cases is only one possible trigger for public health action and the additional surveillance systems are used in concert to signal the risk of human disease, often before the appearance of human cases. Mosquito vector surveillance includes mosquito trapping for speciation and enumeration of mosquitoes to monitor population sizes and relative composition. Virus isolation from mosquitoes can also be undertaken. Monitoring of weather conditions and vector surveillance determines whether there is a potential for MVE activity to occur. Virus isolation from trapped mosquitoes is necessary to define whether MVE is actually present, but is difficult to deliver in a timely fashion in some jurisdictions. Monitoring of sentinel animals indicates whether MVE transmission to vertebrates is actually occurring. Meteorological surveillance can assist in the prediction of potential MVE virus activity by signalling conditions that have been associated with outbreaks of Murray Valley encephalitis in humans in the past. Predictive models of MVE virus activity for south-eastern Australia have been developed, but due to the infrequency of outbreaks, are yet to be demonstrated as useful for the forecasting of major outbreaks. Surveillance mechanisms vary across the jurisdictions. Surveillance of human disease occurs in all States and Territories by reporting of cases to health authorities. Sentinel flocks of chickens are maintained in 4 jurisdictions (Western Australia, the Northern Territory, Victoria and New South Wales) with collaborations between Western Australia and the Northern Territory. Mosquito monitoring complements the surveillance of sentinel animals in these jurisdictions. In addition, other mosquito monitoring programs exist in other States (including South Australia and Queensland). Public health control measures may include advice to the general public and mosquito management programs to reduce the numbers of both mosquito larvae and adult vectors. Strategic plans for public health action in the event of MVE virus activity are currently developed or being developed in New South Wales, the Northern Territory, South Australia, Western Australia and Victoria. A southern tri-State agreement exists between health departments of New South Wales, Victoria and South Australia and the Commonwealth Department of Health and Aged Care. All partners have agreed to co-operate and provide assistance in predicting and combatting outbreaks of mosquito-borne disease in south-eastern Australia.

Resistance to the penicillins was highest in larger urban centres and warrants close attention in those rural centres where treatment with the penicillins continues. Quinolone resistance in gonococci became more widespread in Australia in 2000. Endemic cycles of transmission of quinolone-resistant gonococci (QRNG) in homosexually active men continued in Victoria but declined in New South Wales. Heterosexual endemic transmission of QRNG increased substantially in New South Wales and the proportion of all gonococci represented by QRNG also increased markedly in Queensland and Western and South Australia. All isolates remained sensitive to spectinomycin, but a small number of isolates in a number of jurisdictions showed some decreased susceptibility to ceftriaxone.

From 1 July to 31 December 2000, a total of 12 specimens from 7 patients with AFP were referred to the NPRL. Poliovirus type 3 Sabin-like was isolated from samples from 2 patients with suspected vaccine- associated paralytic poliomyelitis. No viruses were isolated from samples from the remaining 5 patients. Since 1995 a total of 1,325 isolates have been referred for testing from laboratories throughout Australia. Seven hundred (53%) were confirmed as Sabin vaccine-like polioviruses, 542 (41%) were non-polio enteroviruses and 82 (6%) yielded no virus or viruses other than enteroviruses. At Kyoto, Japan in October 2000, the Western Pacific Region of the World Health Organization was declared wild polio-free. This represents a significant step towards the global eradication of poliovirus with one quarter of the world's population free of endemic infections from wild poliovirus.
