It's called common sense, which you seem to be lacking. The CDC and state health departments do have the power to force a quarantine with a court order (which I believe they are seeking). Even the army is quarantining people working in the region even though they may not have had direct contact with patients.
Only if they can produce cause. Somethng that requires evidence of risk like symptoms. Without that all you have left is the ignorant part of irrational fear, or a lack of due process.
The Army is a whole 'nother thing entirely. You are not entitled to all of the same civil rights as a civilian, something that anyone who's been there and done that already knows.
