This book combines modern concepts of epidemiology and molecular biology with computer-modeling. Applying these concepts to the analysis of historical epidemics, the authors show that they were not, in fact, outbreaks of bubonic plague. Biology of Plagues offers a completely new interdisciplinary interpretation of the plagues of Europe, and establishes them within a geographical, historical, and demographic framework. This fascinating detective work will be of interest to readers in the social and biological sciences, and lessons learned will underline the implications of historical plagues for modern-day epidemiology.
