International Law on Biological Weapons: Fit for Purpose?
Associate Professor Treasa Dunworth, University of Auckland
Abstract
The scale and impact of the COVID-19 pandemic is demonstrating how vulnerable our communities are to outbreaks of contagious disease and we are seeing first-hand the way in which disease can wreak social and economic havoc. It is for these reasons that, for at least a century, international law has prohibited the use of disease as a weapon of war. In my presentation I explore whether existing international law for dealing with hostile uses of biological agents (that is, biological weapons) is fit for purpose and in particular I consider the implications of the way in which such hostile use has been traditionally framed as a security, rather than a public health, issue.
