Unde venis? Geographic profiling for the prevention of gastric cancer

In the middle of the 14th century, when the Black Death was decimating the population in Asia and Europe, the Venetian Republic established a system of isolation for travelers arriving to the port of Ragusa (now Dubrovnik), then the gateway for Asian trade to Europe. Before these travelers were allowed to proceed to their destination, they had to spend a period of 40 days (hence quarantine, from the Italian word for 40, quaranta) in a nearby island. The insightful Venetian legislators preceded the concept of incubation, reasoning that those in whom any plague did not develop within 40 days were healthy and could move on.
