The Dramaturgy of Epidemics.

My essay focuses on Charles Rosenberg's provocative and enduring ideal type of epidemic drama in three acts, which he assembled from a vast knowledge of disease history that stretched from the end of the seventeenth century to his then-present pandemic, HIV/AIDS of the 1980s. Reaching back to the Plague of Athens, my essay elaborates on Rosenberg's dramaturgy by questioning whether blame, division, and collective violence were so universal or even the dominant "acts" of epidemics not only before the nineteenth century but to the present. Instead, with certain pandemics such as yellow fever in the Deep South or the Great Influenza of 1918-20, unity, mass volunteerism, and self-abnegation played leading roles. Finally, not all epidemics ended "with a whimper" as attested by the long early modern history of plague. These often concluded literally with a bang: lavish planning of festivals of thanksgiving, choreographed with processions, innumerable banners, commissions of paintings, ex-voto churches, trumpets, tambourines, artillery fire, and fireworks.

Integrative approach using Yersinia pestis genomes to revisit the historical landscape of plague during the Medieval Period.

Over the last few years, genomic studies on Yersinia pestis, the causative agent of all known plague epidemics, have considerably increased in numbers, spanning a period of about 5,000 y. Nonetheless, questions concerning historical reservoirs and routes of transmission remain open. Here, we present and describe five genomes from the second half of the 14th century and reconstruct the evolutionary history of Y. pestis by reanalyzing previously published genomes and by building a comprehensive phylogeny focused on strains attributed to the Second Plague Pandemic (14th to 18th century). Corroborated by historical and ecological evidence, the presented phylogeny, which includes our Y. pestis genomes, could support the hypothesis of an entry of plague into Western European ports through distinct waves of introduction during the Medieval Period, possibly by means of fur trade routes, as well as the recirculation of plague within the human population via trade routes and human movement.

Pandemics: waves of disease, waves of hate from the Plague of Athens to A.I.D.S.

This article briefly surveys the history of pandemics in the West, contesting long-held assumptions that epidemics sparked hatred and blame of the 'Other', and that it was worse when diseases were mysterious as to their causes and cures. The article finds that blame and hate were rarely connected with pandemics in history. In antiquity, epidemics more often brought societies together rather than dividing them as continued to happen with some diseases such as influenza in modernity. On the other hand, some diseases such as cholera were more regularly blamed than others and triggered violence even after their agents and mechanisms of transmission had become well known.
