History for quarantine

Centuries ago people in Europe did not have a good understanding of infectious diseases. But experience taught them that when ships arrived in port and brought strangers, illness would sometimes follow. In Venice, a port in Italy, the practice developed of holding a ship in the harbor for forty days if the passengers were suspected of carrying disease, especially plague. If no one developed signs of illness, the passengers were let ashore. The word for this period of forty days was in Italian quarantena, a derivative of quaranta, “forty,” and it is a source of the English word quarantine.
