Etymology

The word "quarantine" originates from the Venetian practice during the Black Death (14th century) of isolating ships for quaranta giorni (forty days) to prevent plague spread. The forty-day period was likely chosen for biblical or practical reasons (observation time for symptoms). Over time, the term expanded to any isolation period, regardless of duration, while retaining its core logic of disease containment.
