These particular avian flu viruses are capable of causing severe disease and death in humans as well as birds, although at present they are not highly transmissible between people. Should the avian influenza viruses mutate to gain this capability, it will be necessary to institute widespread vaccination of the Australian population. It is not possible to test the vaccines in people for their effectiveness against avian influenza infection prior to a disease outbreak, so an animal model for the disease will be used to assist in optimizing the formulation of flu vaccines and in testing their efficacy in preventing infection or reducing the severity of disease. Ferrets are natural hosts for flu viruses, have similar responses to vaccination as people, and develop a similar disease to humans when infected with influenza. These animals will be used to assist vaccine manufacturers in providing the best type of vaccine for protection of Australians in the face of a global flu pandemic.Read moreRead less

The ageing of the medical workforce, combined with more women entering medicine and changes in doctors preferences over their work-life balance, are all likely to have important effects on the ability of health care system to provide good quality and accessible health care. However, there is little knowledge or understanding of how and why doctors make decisions on how many hours they work, their location of work, including working in rural and remote areas, and decisions to leave the medical workforce and retire. These decisions have important effects on the population�s access to health care and therefore on their health status and quality of care received. The aim of this research is to examine those factors influencing doctors� labour supply decisions through the establishment of the Australian Longitudinal Survey of Doctors (ALSD). The survey will track 5,500 doctors over an initial four year period. The research will provide a rigorous analysis of medical workforce decisions that underpin workforce distribution and the working patterns of doctors. The survey will be used to evaluate and simulate policy changes and provide important evidence to support future policy developments.Read moreRead less

They have to make crucial decisions about their treatment in a very short time. The previous research in this area has been focussed on improving medical outcomes, however it is also apparent that the patients having MET calls are often seriously ill with life limiting illnesses. This study aims to explore the broader aspects of care at this time, which are of paramount importance to patients and their families, such as various aspects of communication, particularly focusing on changing goals of care; and also the symptoms that may be causing significant distress for the patient. This project will provide information that will assist development of interventions that will both aim to improve quality of life and also communication in the setting of medical emergencies in patients with life limiting illness.Read moreRead less

Summary
Birds are commonly infected with bird flu viruses but most of these viruses do not cause disease. However, certain types of bird flu viruses, such as the H5N1 strain, can cause severe illness and death in 100% of infected birds. There is currently an epidemic of H5N1 bird flu occurring in Asia. Occasionally humans become infected by bird to human transmission and since 2003, 130+ people have been infected with H5N1 resulting in 60+ deaths.

However, certain types of bird flu viruses, such as the H5N1 strain, can cause severe illness and death in 100% of infected birds. There is currently an epidemic of H5N1 bird flu occurring in Asia. Occasionally humans become infected by bird to human transmission and since 2003, 130+ people have been infected with H5N1 resulting in 60+ deaths. There are 3 ways in which dangerous strains of the virus may be brought to Australia by; infected people, domestic birds and migratory wading birds. In order to monitor the import of these viruses by migratory birds we will catch and take samples from large numbers of these birds in important areas where they congregate close to humans and poultry farms. We will identify what types of bird flu viruses these birds are carrying and if the viruses are capable of causing disease in birds and humans. We will also see if they can be treated by the influenza drugs that we currently have and we will study these viruses to find new drug targets. These viruses are commonest in ducks. Migratory wading birds and local ducks live in the same habitats so there is the chance that the wading birds and ducks could pass the viruses to each other. There is an additional concern that non-disease causing viruses could mutate in ducks and become pathogenic and pass from bird to bird or even human to human transmission which could cause a major human epidemic of bird flu in Australia. So we will also take samples from local ducks that occur in the same areas as the wading birds and test them for viruses as well. Our results will show what kinds of viruses are being carried by wading birds and ducks and if these viruses are a danger to people and poultry. We can then manage important areas so that humans and poultry do not come into contact with these viruses.Read moreRead less

As of August 2005, the highly pathogenic Avian Flu sweeping through Asia has infected 112 people, killing 57. Over 150 million chickens have been slaughtered in an attempt to stop its spread, but with infection documented in migratory birds, containment may be difficult if not impossible. Experts believe that it is only a matter of time before the Avian Flu virus is capable of human to human transmission which could result in the deaths of hundreds of thousands of people worldwide. Should a pandemic arise, either through purposely-engineered or natural processes such as avian influenza, effective vaccines are unlikely to be available for at least 3-6 months. In such an event, treatment of infection and prevention of spread through post-exposure prophylaxis would be optimal, while pre-exposure prophylaxis would be most suited to key personnel such as army, medical and emergency-response staff. Biota is a world leading antiviral drug discovery company based in Melbourne, Australia with key expertise in viral respiratory diseases, particularly influenza. Biota developed the first in class neuraminidase inhibitors (NAI) drug, zanamivir (Relenza) and through a partnership with Glaxo Smith Kline (GSK) brought it to market. Biota also developed the FluOIA� for the rapid detection of Influenza A and B. Work has been underway at Biota for some time to develop a new generation of influenza drugs designed to be more active and longer acting than the first generation products. These long acting neuraminidase inhibitors (LANI) have the benefit of less frequent administration and a lower treatment dose making them an ideal choice for stockpiling. The proposed project aims to test the antiviral activity of LANI compound against the H5N1 influenza. The results of which could assist in a decision to fast track the clinical development of the compound with the aim of adding to the national stock pile of antivirals, thus helping Australia to prevent, prepare for and respond to a potential avian influenza-induced pandemic.Read moreRead less

Paramedics are front line health staff and in the event of a pandemic will be among the first members of the community to face exposure to infection. This research will explore the attitudes and perceptions of paramedics and their families to working in epidemic conditions, provide prediction of behavioural responses to highly infectious environments, and a clear understanding of attitudes to infection control and use of Personal Protective Equipment (PPE). Knowledge of how to manage and support the responses of frontline health workers to an infectious disease outbreak is critical to the emergency system response. This project aims to mitigate the effects of perceived risk of infection on attitudes and behaviour of paramedics, by informing health promotion and infection-prevention messages to paramedics and their families. This research will also explore the emerging role of ambulance services as a key component of a public health surveillance system to provide an early warning of pandemic disease outbreaks and facilitate implementation of effective disease control strategies. Current triage systems, used for allocation of patients to appropriate treatment and-or quarantine, are not designed for epidemic environments, and may inadvertently facilitate disease spread and delay identification of victims requiring immediate care and-or quarantine. This project will explore the utility of a population-based triage tool to control an infectious disease outbreak by reducing patient-to-patient disease transmission. The project will facilitate expansion of current public health disease surveillance strategies and triage mechanisms for use during an epidemic, to effectively manage increased workloads within a highly infectious environment, whilst maintaining usual emergency medical services.Read moreRead less

Currently, avian influenza A (H5N1) is a concern to public health agencies because of its extreme pathogenicity. At present this strain is not transmitted readily between humans. A number of drugs are available to treat influenza infection in humans and research has shown these to be effective in preventing significant mortality in the setting of seasonal influenza epidemics (specifically the influenza neuraminidase inhibitors _NIs). As a consequence public health agencies around the world have been stockpiling these drugs and developing sophisticated plans for their use if an influenza pandemic was announced. However, there are no data indicating that the neuraminidase inhibitors (NIs) are safe and effective when used to manage pandemic influenza. Neither are there any data to support the use of these drugs on a population basis. Genetic resistance to NIS has been described but it is not clear if this has any relevance to public health. Our research will clarify this issue. This project will develop a number of clinical trials that could be implemented rapidly should pandemic influenza ever be announced by health authorities in Australia-Singapore or Hong Kong. Patients with suspected influenza infection will be asked to provide informed consent prior to commencing NI therapy. Clinical information will then be collected for a period of approximately one month along with some blood samples and swabs from the throat and nasal passages. Data will be analysed as quickly as possible to help inform the continued use of NI therapy as a cornerstone of the public health agency response to pandemic influenza. In addition, the study team will prepare clinical trials to be conducted in essential workers who are likely to receive long-term NI preventive treatment as well as the immediate contacts of people with presumed influenza infection who are likely to receive short-term prophylaxis with NIs.Read moreRead less

The Australian Government has time to develop communication strategies and specific messages that can effectively convey desired information at different stages of the anticipated pandemic. This research team proposes to develop communication strategies (including specific messages, media vehicles, spokespeople, images etc for the different target audiences) that government, medical authorities, NGOs and other relevant organisations can use to increase the public's understanding of the risk. Such strategies will ensure that we can minimise fear, refute misinformation the public may encounter from individuals (e.g., co-workers) or media sources, and enhance the likelihood of the public taking the recommended preventive and remedial actions should an Avian Influenza pandemic occur. Additionally, the research team will then utilise these communication strategies to develop evidence-based guidelines for communication strategies to be used in cases of similar serious health threats in Australia. Based at the University of Wollongong, the project team is a sophisticated and synergistically qualified team of experts. The team includes: a main media health promotions expert (Associate Professor Sandra Jones); two marketing communications experts, one of whom has an academic focus and the other a practitioner focus (Professor John Rossiter and Dr Max Sutherland respectively); a public health and medical expert in health behaviour change (Professor Don Iverson); a senior public health campaigns expert (Professor Chris Puplick), and an expert in communicable diseases and infection control education and programs (Professor Julian Gold).Read moreRead less
