Finally it reviews the threat of further monopolization of knowledge and its commercial applications, and the implications for trust and trustworthiness in health care. It concludes with suggestions for action. Questioning the ‘genohype’: some pertinent questions from the SARS epidemic The microbial agent involved in the severe acute respiratory syndrome (SARS) epidemic of 2002–3 was swiftly identified and sequenced in a remarkable collaboration between otherwise highly competitive laboratories in Asia, Europe, and North America. These early exchanges, however, soon gave way to mutual wariness at the point when intellectual property claims were filed for the pathogen’s sequences and other patentable findings with commercial potential. And regardless of the rapid success, the epidemic quickly subsided despite the absence of reliable diagnostics, vaccines or efficacious therapies – an outcome attributable to traditional institutional responses such as isolation and contact tracing, and possibly also to personal risk avoidance, the contributions of seasonality effects and cross-reacting immunity from related endemic microorganisms. Most importantly, the economic and financial stakes involved ensured that SARS would not be a ‘neglected disease’ of the world’s poor. The case of SARS prompts a number of questions that could be asked of emerging biomedical technologies in general: • How important are biomedical advances (including genomics) to population health and to patient care (distinguishing perhaps between knowledge-based practices and coping responses, as opposed to consumable commodities)? • What is the relative significance of genetics in the etiology (and social ecology) of health and disease? • What advances can genomics be realistically expected to contribute to disease control, diagnostic aids and treatment? • What are the likely trajectories of genomics research and development, given the trends in funding of biomedical research, patent regimes, intellectual property rights and market-driven product development, and the unresolved problems of the neglected diseases? • What environment would enable the useful potential of genomics to be realized – for an equitable harvest of benefits and a humane deployment of genomic technologies? • What processes and institutions are needed to deal with these policy and ethical issues? 148
The social ecology of health and disease The decline in mortality from infectious diseases in early industrializing countries in the 19th century owed little to medical science and its derived technologies (McKeown 1971). In England and Wales, for example, the mortality rate from respiratory tuberculosis, a major killer, declined by more than 85% between 1838 and 1945, well before the discovery and isolation of the antibiotic streptomycin in 1947 and also well before the widespread availability of BCG vaccination for protection against tuberculosis from the 1950s onwards. McKeown and others identified food intake and nutritional status, potable water supplies and environmental hygiene as the key factors in the decline of infectious mortality. Mortality alone is an inadequate measure of population health. Nonetheless, recent efforts to devise more discriminating measures of disease burden that take into account morbidity, disability and functional capacities, and quality of life have not seriously undermined McKeown’s thesis, notwithstanding the efficacy of some modern therapeutics and procedures in controlled, favourable circumstances. Biomedicine at best has contributed only modestly to improvements in population health. This is the context in which the future benefits of genomics must be evaluated. The current focus on genome technology and the particular imagery around the human genome is unfortunately diverting attention from public health approaches to combating disease, ill health and poverty. Life is much more complex than the pattern of the molecules in our genes. It is also important to know why and when some genes in some people are switched on and why others are switched off. A major part is played by the microenvironment inside cells, but this is influenced by the macroenvironment, the body as a whole and the outside world. A host of physical and social factors play a role, and public health approaches, embedded in socioeconomic policies, will probably remain much more important than high-tech solutions in improving global health. Justifiable exuberance or premature genohype? Is genomics the panacea for human illness and infirmity? The director of the US National Human Genome Research Institute declared in 1999 that the benefits of mapping and sequencing the human genome ‘would include a new understanding of genetic contributions to human disease and the development of rational strategies for minimizing or preventing disease phenotypes altogether’. There would be further prospects of ‘genetic prediction of individual risks of disease and responsiveness to drugs…and the development of designer Gene technology 149
