Abstract We explore the space–time and mortality dynamics of recent infectious diseases outbreaks which have occurred in a large number of developed and developing countries. We fully acknowledge the heterogeneity of infectious diseases. We find that many outbreaks exhibit spatial dependence, due to the international movement of people and goods. All countries are exposed to these negative cross-border health externalities, which can be triggered by climate shocks. The mortality consequences are much more severe in developing countries. Paying attention to spatial dependence has important implications for economic research and international policymaking.
