Summary
Multiple Sclerosis (MS) is a severely debilitating neurodegenerative disease, affecting over 16,000 Australians. There is a need to examine which factors drive the progression of this disease. We examine the role of two viral infections on MS activity. It has the potential to contribute to antiviral interventions that might prevent relapses and-or decrease the clinical progression of this debilitating disease.
Modelling The Evolution Of Hepatitis C Virus By Integrating Large Sequence- And Immunological-databases.

Summary
Two hundred million people are infected with the Hepatitis C virus. There is no vaccine and the rate at which new strains of the virus arise enable it to evade the human immune system. This study aims to decipher how new viral strains are generated and transmitted, thereby enabling the development of new vaccines.

Summary
The hepatitis C virus (HCV) continues to spread among injecting drug users (IDUs) in Australia at a very high rate, despite success in preventing the spread of HIV in the same groups; the complete reasons for this remain unclear. There is an urgent need for the HCV epidemic among IDUs to be contained. To do so, we must better understand the ways in which it is spreading among IDUs.

There is an urgent need for the HCV epidemic among IDUs to be contained. To do so, we must better understand the ways in which it is spreading among IDUs. Much is known about risk behaviours of individual IDUs and how they contribute to HCV transmission; much less is known about how these behaviours are modified by the influence of the IDUs peer group, especially their immediate and intimate social networks. Despite its importance in influencing attitudes and behaviours, and therefore HCV transmission, this has never been studied in Australia, nor, in relation to HCV, in the world. We hope that by studying social and risk networks of IDUs we shall discover new ways in which control of the HCV epidemic can be achieved in Australia. We intend to do this among two groups of young IDUs, one of Vietnamese ethnicity, located in the one suburb of Melbourne. By using field techniques for gathering information (ethnography), and sophisticated analytic techniques to understand how these networks are formed and influence behaviours, we hope to be able to identify interventions which work at the level of the social group rather than the individual in bringing about the behaviour change necessary to prevent HCV transmission. To ensure that the risk networks we describe are as influential as they appear, and to discover more about the variability of HCV, we will also be investigating the relationship between the various strains of HCV in members of the IDU networks, particularly as another measure of the connectedness of networks and network members. This will be done using sophisticated genetic analysis of the HCV obtained from network members by blood test.Read moreRead less

Summary
Australia is one of the few countries in the world known to be free of rabies. A dramatic impact on this status occurred in 1996. A flying fox in northern NSW was found to be infected with a rabies-like virus. Within 16 weeks of this discovery the first human case occurred. A further human case has now been reported. The newly discovered virus, named Australian bat lyssavirus (ABL) was found to be closely related to, but distinguishable from, rabies virus.

A flying fox in northern NSW was found to be infected with a rabies-like virus. Within 16 weeks of this discovery the first human case occurred. A further human case has now been reported. The newly discovered virus, named Australian bat lyssavirus (ABL) was found to be closely related to, but distinguishable from, rabies virus. Rabies virus is responsible for thousands of human infections each year, mainly in Asia and South Asia where it is endemic in urban dogs. In contrast, other rabies-like viruses have caused only a handful of human infections. Although the number of human cases of ABL is likely to remain low, each of the two known cases has aroused a great deal of public anxiety. The natural hosts appear to be various species of bats which collectively have a distribution along the entire northern and eastern coastlines. The number of potential exposures is therefore quite large and state health departments are devoting considerable resources to dealing with public concerns. This project will establish clearly defined risk factors for exposure to ABL and will allow health authorities to better manage expensive and limited vaccine and therapy resources.Read moreRead less
