Not true. Quarantine is exactly the restriction on movement and interaction of people (and goods) not known to be sick.If you're scared, sick or high risk stay at home. "Quarantine is when you restrict movement of sick people, Tyranny is when you restrict the movement of healthy people."
Perhaps you're thinking of isolation; which is one of my favorite Joy Division songs.
Help!!!!!! We're being taken over by nannies..........
