Every eight seconds: AIDS revisited
Introduction
Abstract The National Academies Forum is a coordinating body of Australia's four learned academies. Its symposia investigate issues of public interest from the intellectual perspectives represented by the Academies. This Symposium will consider HIV/AIDS from the medical and social viewpoints; it will also consider important aspects of the disease from personal, human and moral dimensions. The tragedy of HIV/AIDS has been recently reinforced by media exposure of the extent of the problem in southern Africa and of the emerging crisis in Papua New Guinea. This introductory paper looks at ways in which Australians have responded to issues of HIV/AIDS since the early 1980s and how national strategy might best be directed in the twenty-first century.
Consensus or complacency: 'Post AIDS' but pre what?
Abstract It is important to understand that Australia's success in fighting AIDS and in developing effective public policy responses to its challenges owe a great deal to good luck and not just good management. A combination of particular people and peculiar circumstances led to our responses being of a nature and quality which were not observed in most similar developed countries where partisan politics featured prominently in the early days of AIDS policy debate. Since those early days the political climate in Australia has changed significantly and the partnership which keeps AIDS policy on track is finely balanced. Anything which looks like a 'failure' of policy for example, increases in rates of new infections challenges these delicately balanced forces and must be taken very seriously.
HIV and AIDS: A geographical overview
Abstract The HIV/AIDS epidemic in Australia is increasingly unique in global terms. The Australian domestic response is still justifiably regarded as exceptionally effective. We have reduced the numbers of new infections among gay men to very low levels and we have continued to prevent epidemics among injecting drug users and sex workers. The Australian situation is a stark contrast to that of other nations in our region. The Asia-Pacific Region is the site for a number of exploding epidemics that need swift action now. It is urgent that Australian expertise in areas like needle exchange, community development and vaccine trials be made available to our neighbours in the region. This is a humanitarian issue and a security issue. With increasing rates of mobility and migration throughout the region, and the rise in HIV and AIDS in nations like PNG, it is also a domestic public health concern. Australia's domestic response to HIV/AIDS deserves to be regarded as the best in the world. It is now the time for us to make sure that our international commitment, especially in the Asia-Pacific, is regarded equally highly.
The origin of AIDS: Can science afford to ignore it?
Abstract There is a crisis of public faith in science and scientists. Recent research shows concern over scientific ethics, transparency and who benefits from R&D, exemplified in the GMO debate. Scientific discussion of one hypothesis, that AIDS may have started in an early polio vaccine, has been systematically suppressed for more than twelve years. Julian Cribb calls for an independent international multidisciplinary inquiry into the origin of AIDS, arguing it is essential to human health, to preventing new pandemics, and to safeguard public trust in science.
HIV/AIDS in Africa
Abstract If you are an Australian, you can expect to live around 78 years, but if you are a Zambian, your life expectancy is now 37. In 1991, it was 49. Since the International HIV/AIDS Conference in Durban, South Africa, in July 2000, statistics such as these have conveyed to the world some measure of the catastrophic impact of the epidemic. The loss of life and the effect on individuals and families is devastating. So too is the loss of development gains of the past decade. Families and communities are over-burdened; employers are losing workers in their prime; economies are faltering; the demand on the public health sector to care for sick and dying far outstrips the resources available. These factors, compounded with extreme poverty, have created highly vulnerable groups women, youth, orphaned children for whom neither the public sector nor community are able to care. The international community, including Australia, considers the epidemic the paramount threat to Africa's development. Australia is working with African governments and community groups to care for those affected by it and to strengthen the responses of government, employers, researchers and communities. Australian-government-funded activities largely through Australian NGOs are combining technical strategies (condom promotion, reduction of STDs and behaviour change) with broader responses, including community prevention and care, outreach to highly vulnerable groups, support for national level research and capacity building.
Focus on Asia and the Pacific: Major issues
Abstract AIDS continues to wreak tremendous social and human damage in Asia. In some countries, such as India, Burma and Cambodia, descriptions of ‘out-of-control’ epidemics are common. In others, such as Vietnam, Laos and Malaysia, more measured terms are used and observers are hopeful that prevention policies are proving to some extent effective. Thailand, long regarded as the epicentre of AIDS in this region, is usually held up as a model of a country that has tamed the havoc that AIDS embodies through progressive policies and committed social support. Unfortunately, the reality is not so clear-cut. Dr Lyttleton will outline ways in which the presence of HIV/AIDS continues to pose complicated dilemmas for prevention and care programs in the SE Asian region, particularly in Thailand where, after years of decline, rates of infection in some sectors are again beginning to rise.
Key issues for Australia: Panel discussion
Abstract Australia has had a comprehensive national approach to responding to HIV/AIDS since the first National HIV/AIDS Strategy in 1989. We are now in the second year of our fourth National HIV/AIDS Strategy. We have well developed networks of people living with HIV/AIDS, researchers, clinicians, government officials, and community based organisations which, most of the time, work together very effectively. To guide our way forwards, we have a substantial body of high quality evaluation of the work we have done. Yet the language used in the HIV/AIDS sector to describe our work in a changing epidemic refers consistently to the complexity of the issues that confront us and the responses that are required to meet the challenges. The speakers in this session will briefly outline a few of the key issues which confront PLWHA organisations and AIDS Councils in responding to the epidemic and this will lead into a broader discussion of the Australian response.
Ian Rankin is an ex-president of the National Association of People Living With HIV/AIDS (NAPWA). He is a current member and ex-president of the local AIDS Action Council of the ACT. He has been a member of the Australian National Council on AIDS and Related Diseases Research Advisory Committee and the ACT Sexual Health and Blood Borne Diseases Advisory Committee. A public servant for ten years in the employment policy area, Ian has been diagnosed with HIV infection for over 14 years. He is currently undertaking undergraduate studies at the Australian National University in political science and sociology. Abstract Archbishop Pell and Ian Rankin will present their views on a number of topics:
Circumcision and prevention
Abstract An increasing number of national, cross-sectional and longitudinal studies in Africa and Asia are showing a 2- to 8-fold protective effect of male circumcision against HIV infection. Our studies have demonstrated that circumcision apparently has no effect on the epithelium of the glans penis, which is always keratinized, thus protecting it from HIV infection. This is in contrast to the inner surface of the foreskin, which is weakly keratinized, but well supplied with Langerhans (Dendritic) cells which contain HIV receptors. These cells are likely to be the primary point of viral entry into the penis of uncircumcised men. Adolescent male circumcision should be seriously considered as an additional means of preventing HIV infection in all countries with a high prevalence of infection. The definition of safe sex should include a warning about exposure of the foreskin to infected semen or vaginal secretions, even if penetrative intercourse has not occurred. In the future, we may be able to develop a range of topically active receptor blockers that could prevent HIV binding to the Langerhans cells in the foreskin and the vaginal epithelium.

Can we overcome viral resistance to anti-AIDS therapies?
Abstract There are now a dozen or so drugs approved for use in treating HIV infection. These currently available drugs target primarily the enzymes reverse transcriptase and the aspartyl protease from the HIV virus. One of the major problems with these drug treatments is that, over time, the virus becomes resistant to the effects of the therapy. Why is this? How might we overcome viral resistance to current drug regimens? Will it be possible to design drugs that can outmanoeuvre the virus?
How close is a vaccine?
Abstract The need for an AIDS vaccine is imperative. The statistics of HIV infection are horrendous: more than 16 million people have died of AIDS, more than 34 million people are living with AIDS, mostly in the developing world, and nearly all will die of AIDS within the next two decades. Although other measures have slowed the progress of HIV only an AIDS vaccine can end the HIV/AIDS pandemic. Although after 15 years and more than 30 vaccines having been tested in humans, only one vaccine is currently in Phase III trials and scientifically unlikely to be successful. The failure to find an AIDS vaccine has been both political and scientific. Currently the world spends $US 20 billion on HIV/AIDS but only $US 300 million on AIDS vaccine research and development less than 2%. Much of this is from national research agencies for basic research. Industry has not had the incentives to invest heavily in product development and has had virtually negative incentives to invest in creating products for developing countries. Furthermore, it is now likely that an AIDS vaccine will be intricate and multi-component in which ownership of associated intellectual property will be complex, making it difficult for individual organisations to invest. National governments, including Australia, need to take a more active role in AIDS vaccine development, particularly in the area of providing funds for clinical trials. At the scientific level, most conventional approaches have failed. Protein based vaccines have so far failed to induce the correct form of immunity associated with protection and attenuated vaccines have proved too dangerous. New recombinant DNA approaches are more encouraging and in some cases have protected monkeys against infection. One approach being used by an Australian vaccine consortium funded ($27 million) by the United States National Institutes of Health is to use two different recombinant DNA vaccines consecutively. This has produced unprecedented levels of immunity against HIV and could protect against infection. Trials of the vaccine will commence in Sydney within 2 years. However, the possibility exists that no vaccine will completely protect against infection and will only prevent the development of full-blown AIDS. A useful vaccine is unlikely to occur within the next 5 years so a long-term commitment is required for such programs.
Presentation of the Hope Rose
Remarks by Professor Malcolm Gillies Towards the end of the Second World War, at a time of immense human loss, the precious prize of peace was held up and projected in the birth of the Peace Rose, now probably the most famous rose in the world. We, here today, together, are very much engaged against the world-savaging war of HIV/AIDS. Just last month, at the International Rose Festival in Adelaide, the South Australian Premier, John Olsen, launched the world's first 'cause' rose for HIV/AIDS. It carries the wonderful name of Hope our hope for a vaccine in this new millennium. Eventually, in stature, it could become a sister to the Peace Rose. Its production was commissioned by the Melbourne charity, the Australian AIDS Fund Incorporated, which came into being as a response to the appalling discrimination meted out against New South Wales pre-schooler, Eve van Grafhorst, the first Australian child to be HIV-infected via a blood transfusion. Her story, and that of the Australian AIDS Fund, are on the website www.aids.org.au. On this eve of World AIDS Day, I have been invited especially to share Hope with all of you the Australian-produced Hope Rose. Our guest with those first precious blooms is Kerrie Hadfield from Queanbeyan. Kerrie was herself suffering from a life-threatening medical condition when, as a 10-year-old in the then Prince of Wales Children's Hospital (now the Sydney Children's Hospital), she met Eve van Grafhorst, another young AIDS hero of that time, Troy Lovegrove, and other HIV-infected children in Ward C5, the AIDS ward. These meetings left an indelible mark on Kerrie's life and inspired her support for HIV-positive people. We are pleased that Kerrie is here to present the Hope Rose on behalf of the Australian AIDS Fund. Presentation of Hope Rose by Kerrie Hadfield I am very honoured and also very proud to share your company today and to bring you this very special rose, which I hope can find a home here in the grounds of the National Library of Australia. What a joy it is to be open and hopeful, compared to those early days of the mid-eighties, when ignorance and fear of people with HIV was more prevalent than the disease itself. During my many hospital stays, we staged regular water fights on the wards. The plastic syringes, drop bags and tubes made great bombs and water pistols for our battles. I still remember that day in 1987, when we were suddenly banned from touching these things, and watched as the nurses put them into huge yellow plastic bags which were later burnt. In many places in Australia today, these fears are still not far from the surface, and even some doctors are not fully educated on the virus. At the moment, the Hope Rose is still very much an infant. We are hoping that there will be enough cut blooms to show up in World AIDS Day celebrations in Sydney, Melbourne and Adelaide, but it will be out in strength next year as a fund-raiser for all HIV-positive people not just in Australia, but throughout the world. I stand before you today with the spirits of my beautiful HIV friends by my side. Troy, Adam, Skye, Blake and Eve are not here to share with you their love and inspiration that they were to my life, but their message is like that of this rose which carries hope within its beautiful petals the hope that this world will see an end to AIDS. Please keep it with you always.
Legal and ethical considerations
How can spatial information systems assist in the fight against AIDS?
Abstract Spatial Information Systems apply rapidly developing computer-based technologies and methodologies to the collection, storage, analysis, retrieval, modelling and visualization of spatially referenced information. They have considerable potential for assisting in monitoring the spread of HIV/AIDS and hence are useful in planning where preventative strategies can be introduced to maximize their effects. Some examples of the use of SIS in this way are drawn from Asia and Africa. Some of the barriers which currently prevent the wider use of SIS for these purposes are discussed.
The Lucky Country? Australian Adolescents and HIV/AIDS
Abstract Unlike their peers in many other countries affected by HIV/AIDS, few Australian adolescents have been infected with HIV. Nevertheless, it is clear from research that young people engage in a wide variety of risk practices, including sexual intercourse without using condoms, that are likely to be unsafe. In some marginalised groups, such as young people who are experiencing homelessness or who are attracted to peers of the same sex, risky practices are a relatively common occurrence. Australia's prevention education programs have achieved considerable success in promoting safe sex and safe injecting practices. These programs must be reinforced and expanded so that our young people remain alert to the means of avoiding infection with HIV and other blood-borne viruses and act accordingly.
Biomedical strategies for responding to the HIV epidemic
Abstract HIV infection is an infectious disease like no other we have seen. Transmitted via sexual or blood contact, or from parents to newborns, it has the capacity to kill most people who become infected, but only after a long period of dormancy. When this infection revealed itself in the early 1980s, we discovered that we were not well prepared. After nearly twenty years of experience, we have learnt much about prevention and treatment, but the number of people newly infected continues to grow in much of the world. Biomedical science had little to offer at the start of the HIV epidemic, but its role has steadily increased, in partnership with the political, social and behavioural initiatives that have been at the centre of most national responses to the HIV epidemic. Initially the role of the biomedical sciences was to provide an understanding of HIV transmission and disease progression, and the characteristics that affected the likelihood that these events would occur in individuals. This knowledge provided the basis for prevention programs, as well as counselling people with HIV infection. More recently, there have been major advances in the effectiveness of therapy. For many of those in a position to have access to the range of expensive new pharmaceutical agents, disease progress has been halted or at least greatly slowed. The durability of this benefit remains uncertain however, and the vast majority of people with HIV infection in the world cannot even gain access to minimal analgesic or palliative treatment. As this situation will not change in the foreseeable future, there is an urgent need for a vaccine. Multiple scientific, technical and ethical challenges lie in the path of vaccine development, but must be faced if HIV is ever to be seriously countered.
Complacency or complexity: Managing gay sex
Abstract There is understandable concern about the upturn in unprotected anal intercourse among gay men. This upturn has been documented in a number of studies of gay men living on the east coast of Australia (Sydney, Melbourne and Brisbane). Recent research has turned to uncovering the reasons for this upturn. The findings of the research indicate a number of plausible hypotheses some of which have been confirmed. These include: post-crisis climate; optimism about new treatments; and the development of complex risk reduction strategies among a number of gay men. There is little evidence for the widely held view that gay men have become complacent.
AIDS and the arts
Abstract The arts, whether visual, literary or performing, have tremendous potential to bring home the issues faced by those affected by, or living with, HIV/AIDS. Illness and art, however, have always had a stormy relationship. The impoverished painter in his attic bemoaning the loss of his consumptive lover may well be an emotive subject for an opera, but does such work help to articulate the joys, tragedy and suffering experienced by such individuals, or does it distract us from the reality of the situation? This paper presents a profile of the arts in Western Society and literature in particular over the last eighteen years and seeks to demonstrate how it has been simultaneously both therapy and challenge, to the reader and writer alike.
Documenting AIDS: The response from cultural institutions
Dr Jonathan Kelley, PhD (University of California, Berkeley), is Director of the International Social Science Survey (ISSS), Professorial Associate at the University of Melbourne's Melbourne Institute of Applied Social and Economic Research, and Head of the International Survey Project at the Australian National University's Research School of Social Sciences. He has published widely in refereed journals, both in Australia and internationally, on public opinion, popular culture, religion, and inequality. Abstract International Social Science Survey/Australia data show that among the Australian citizenry at large in the early 1990s, very few people had any AIDS victims among their acquaintance, but that quite a lot felt at least slightly at risk. The degree of sympathy felt for AIDS victims varied greatly according to the transmission route, as is even more true of blame. Many people who blamed AIDS victims nonetheless felt sympathy for them. Ideal financial responsibility for health care for AIDS acquired by most transmission routes was seen as shared between the government and the person with AIDS, with the heavier share being shouldered by the person. How has this context changed during the 1990s? Is contact with AIDS victims more widespread? Has that increased sympathy? These questions and issues of social differences in attitudes towards persons with AIDS form the focus of this paper.
