This proposal combines the extensive scientific skills and experience of the Institute of Medical and Veterinary Science (IMVS), Adelaide with the experience and existing capability of Ambri Ltd, Chatswood Sydney, to adapt an existing ICS_ Biosensor for the detection of avian influenza virus in clinical specimens. The existing ICS_ Biosensor has been shown to have reactivity with inactivated Influenza A (H1N1 and H3N2 _ current, circulating human strains) and with recombinant Nucleoprotein. This unique mix of experience and infrastructure will permit the demonstration a rapid, point-of-care test for Avian Flu within the tight six months schedule.Read moreRead less

Summary
Mobile phone use is increasing in Australia, especially among children and young adults. This study is the Australian arm of an international multi-centre study that will investigate exposure to radiofrequency radiation from mobile phone use during childhood and adolescence and later onset of brain tumours in people between the ages of 10 and 24 years. There is considerable community concern and scientific interest about possible health effects from mobile phone exposure in young people and this ....Mobile phone use is increasing in Australia, especially among children and young adults. This study is the Australian arm of an international multi-centre study that will investigate exposure to radiofrequency radiation from mobile phone use during childhood and adolescence and later onset of brain tumours in people between the ages of 10 and 24 years. There is considerable community concern and scientific interest about possible health effects from mobile phone exposure in young people and this multi-centre study will provide important information about such cancer risks.Read moreRead less
Surveillance And Analysis Of Avian Influenza Viruses In Wild Birds In Australia

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. There are 3 ways in which dangerous strains of the virus ....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. 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
Production Of Nasal Filters: Enhanced Prophylactic Protection From Aerosol Exposure

Summary
Influenza is a highly contagious disease that is transmitted via infective secretions containing the virus. An infected person produces tiny droplets of these secretions when coughing, sneezing, and talking, and the droplets are disseminated into the air where they are subsequently inhaled by others. A common way of preventing such transmission is to wear a mask to prevent droplet inhalation. While such masks may greatly reduce exposure, they do not eliminate it, as some viruses can pass around ....Influenza is a highly contagious disease that is transmitted via infective secretions containing the virus. An infected person produces tiny droplets of these secretions when coughing, sneezing, and talking, and the droplets are disseminated into the air where they are subsequently inhaled by others. A common way of preventing such transmission is to wear a mask to prevent droplet inhalation. While such masks may greatly reduce exposure, they do not eliminate it, as some viruses can pass around the edges of masks, particularly if it fits poorly, and also a small percentage can pass through the filter material. While influenza is usually not a major health problem in the general community, the emergence of a more hazardous strain will place an additional burden on health care and other facilities, and requires the development and optimization of measures to minimize virus spread and protect those who are exposed. The aim of this project is to build small filters that can be worn in the nose to provide additional filtration of inhaled air. These filters would be worn in combination with a mask in high exposure circumstances, such as by health care workers when treating infected patients or could be used when a mask was not normally worn to provide effective and discreet protection, such as in crowded public places. Developing such filters builds on our experience of making small samplers worn in the nose to measure allergen exposure. This experience is combined with advanced filter materials developed by leading US researchers that permit the efficient filtration of particles as small as viruses. This project will be conducted in collaboration with a leading Australian design group, and we will design and evaluate such filters for their ability to capture virus and thus protect the wearer. The filters should provide an intuitive, effective and inexpensive method to be used in combination with other hygiene measures to increase personal protection from acquiring highly transmissible respiratory diseases, particularly influenza. We expect to have prototypes of the filters available in 6 months so that production can commence.Read moreRead less
