Quarantine has always been a precautionary measure, applied to both sick and healthy people. The point is that you don't know who falls into which category.
The origin of the word is quarantena, Venetian for "40 days", the period of time a ship suspected of carrying disease had to wait outside the harbor.
No. Quarantine is where you restrict the movement of people who may be carriers for infectious diseases. Because spreading infectious diseases makes healthy people sick. You do realize that healthy people can get sick..right? Like...you know that some people who are sick were healthy prior to that? You realize that closing a door to a room doesn’t make the room disappear..right?

Except they didn't really restrict those kinds of people completely, right? All those exceptions to the rules of people who didn't have to quarantine, irregardless of whether they may be a carrier.
