I understand the technical meaning of the word, I was just using the language of the OP, “self-quarantine”. When I said I would self-quarantine I meant more than what you are saying, I mean literally shelter in place, no contact with anyone.
Well...I would not go to those lengths, unless I suspected that I had contracted the disease. I would do it to protect others...
But I did not get the impression that you were referring to that sort of a situation.
Knowing that if I remained hydrated and had some calorie intake, some general care to prevent bacterial infection, I would have a better than 50/50 chance of beating it.
Or I would just die in place...in self imposed quarantine.
