TED-ED: Mysteries of vernacular: Quarantine - Jessica Oreck and Rachael Teel

The video explains the concept of quarantine, originating from the 14th century during the Bubonic Plague in Europe. It describes how the port city of Ragusa implemented isolation measures for ships to prevent disease spread. The term 'quarantine' comes from the Italian word 'quaranta', meaning forty, referring to the 40-day isolation period. Over time, the term expanded to describe any form of isolation, not just for plague-related cases.
