Public health in reverse; this term has been applied to the deliberate use of microorganisms to cause and spread disease (Harris & Paxman, 1982, p. xii). Biological warfare is not only a perversion of science; it goes against the very heart of human efforts to reduce and eliminate infectious disease as a scourge of society. The developed world had assumed that the impact of natural infectious diseases had been eliminated by, among other things, clean water, antibiotics and vaccinations; we know now that this is far from the truth. Since the early 1970s, at least 30 previously unknown infectious diseases, have been identified for which there is as yet no fully effective treatment (US Department of Health, 2002). One could also be forgiven for believing that the 1972 Biological and Toxin Weapons Convention (BTWC) had eliminated the threat posed by the deliberate release of these microorganisms. Unfortunately, since the convention came into force in 1975, the historical record has been unequivocal. Both the former Soviet Union and Iraq have pursued major clandestine bioweapons programmes concealed both within government and, ostensibly, civil and academic facilities, such as vaccine and other pharmaceutical plants. The misuse of ‘dual‐use’ knowledge, facilities and technologies and the proliferation of potential biological weapons remains a risk, despite the existence of the BTWC, and underscores the need to find more effective ways of combating and deterring the acquisition, possession and use of offensive bioweapon capabilities. We should not forget that the term ‘bioweapons’ applies to the misuse of microorganisms to cause disease or harm to humans, animals and plants—indeed, the threat to crop monocultures, food supplies and agricultural trade should not be underestimated (Chalk, 2001; Wheelis et al ., 2002). A major stumbling block with the current BTWC is that it contains weak compliance provisions. Article …
