Ships as Historical Corridors of Contagion: From Plague to Hantavirus

This article analyzes the historical and ongoing role of ships as ideal environments for disease outbreaks, ranging from the medieval plague to recent cases of Covid-19 and hantavirus. Due to confined spaces and prolonged close contact among passengers and crew, vessels facilitate the rapid spread of airborne, contact, and foodborne pathogens. The report highlights recent incidents, including a hantavirus outbreak on the cruise ship MV Hondius, which led to passenger evacuations, and a gastroenteritis suspect case on a ship in Bordeaux, France. It references expert opinions from historian Alfred Crosby and maritime medicine specialist Jean-Pierre Auffray, who emphasize the dual risks of land-based transmission and onboard infection. The text also recalls the 2020 pandemic era, citing the Zaandam cruise ship and the French aircraft carrier Charles de Gaulle as notable examples of maritime health crises. The analysis underscores that despite differences in vessel types and demographics, the logic of confinement and fear remains consistent across centuries, making ships vulnerable to epidemics far from immediate medical assistance.
