|Quarantine|
Amirhossein Alizamani
A quarantine is a restriction on the movement of people, animals and goods which is intended to prevent the spread of disease or pests. It is often used in connection to disease and illness, preventing the movement of those who may have been exposed to a communicable disease, yet do not have a confirmed medical diagnosis. It is distinct from medical isolation, in which those confirmed to be infected with a communicable disease are isolated from the healthy population. Quarantine considerations are often one aspect of border control.
The word quarantine comes from quarantena, meaning "forty days", used in the Venetian language in the 14th and 15th centuries. The word is designated in the period during which all ships were required to be isolated before passengers and crew could go ashore during the Black Death plague. The quarantena followed the trentino, or "thirty-day isolation" period, first imposed in 1347 in the Republic of Ragusa, Dalmatia (modern Dubrovnik in Croatia).
