This article revisits the origins of internationalism in the field of health and shows how the cholera epidemics of the nineteenth century, much like the current coronavirus crisis, brought global differences such as social inequalities, political hierarchies, and scientific conflicts to the fore. Beyond drawing parallels between the cholera epidemics and the current crisis, the article argues for combining imperial and social histories in order to write richer and more grounded histories of internationalism. It explores this historiographical and methodological challenge by analysing the boardrooms of the international sanitary conferences, Middle Eastern quarantine stations catering for Mecca pilgrims, and ocean steamships aiming to move without delay during a worldwide health crisis.
