This essay revisits the scholarly production around three major pandemics in the region: (a) the Third Plague Pandemic; (b) HIV/AIDS in the 1980s; and (c) COVID-19. The essay aims to provide a comprehensive set of resources (both printed and digital) in four languages (Portuguese, Spanish, English, and French) to examine how scholars have approached these phenomena and how their scope and interpretations have changed over time. Historians of health paid particular attention to sociocultural aspects of the disease, which enabled them (...) to consider usually-neglected actors, such as patients of Indigenous and African descent with their own medical traditions. This added more complexity to our understanding of how these pandemics were fought and received. In addition, the essay suggests that COVID-19 prompted the emergence of historians of health as public scholars. They actively used social networks and other digital tools not only to communicate about the long history of diseases and pandemics in the region, but also to provide an authorized or informed perspective amid misinformation and fake news. In addition, the internet was crucial to the development of helpful databases and virtual conferences beyond academic campuses and paywalls. (shrink)
