When humans travel, they tend to bring their infectious diseases along. With Covid and air travel we have seen that an outbreak can become a global pandemic within weeks. With historic, slower mode of travels, the situation is more complex. Consider a sailship going half way round the world - by the time it reaches the destination, the pathogen may have run out of hosts to infect and thus the disease may have died out without any intervention. I spotted a paper applying the tools of ecological theory to the intercontinental transfer of pathogens in the times of sail and steam and found that topic really fascinating, so I mixed in a bit of Covid and air travel and some pre-historic travellers to widen the scope and made it my latest feature which is out now.

This painting by Jacob Knijff (1639–1681) purportedly shows “Ships, Galleys and Other Vessels off an Italian Port”, although the location could not be identified and the scene is not thought to depict a specific event. (Image: Jacob Knijff/Wikimedia Commons.)
