You have left out another difference: whether the person is known to be infected.

Many people reserve the word "quarantine" for those exposed, but not known to be infected; and use "isolation" for those exhibiting symptoms. They are expected to appreciate the medical care, although that is not relevant in the case of the common cold. No one has objected to the isolation of people exhibiting symptoms of Ebola after exposure.

The response to SARS quarantines seemed to me pretty similar to the response to Ebola quarantines.
