In this episode, we meet Prof. Patrick Wallis to discuss some of his previous work on pandemics and plagues. We look at the comparative magnitudes of some of the worst disease outbreaks and discuss how the perceptions of pandemics, the norms around personal responsibility and the nature of policy responses have all evolved over time. We also consider the nature of media reporting across cases and how government action may have been influenced by the socioeconomic status of the initial sufferers.
