Quarantine
Quarantine "is used to separate and restrict the movement of well persons who may have been exposed to a communicable disease to see if they become ill.". The term is often erroneously used synonymously with isolation, which is "to separate ill persons who have a communicable disease from those who are healthy.". The word comes from the Italian (seventeenth century Venetian) quarantena, meaning forty-day period. Quarantine can be applied to humans, but also to animals of various kinds.
