This digital project brings together half a million pages of primary sources (textual and visual) based on the history of disease and epidemics. The collection is organized around several notable episodes of epidemic diseases such as cholera, the plague, smallpox, influenza, syphilis, tuberculosis, and yellow fever. The project explores the biological and medical facets of each episode along with its economic, political, social, and cultural ramifications. Finally, the collection is framed by a timeline of episodes of significant diseases and epidemics.
