Really? Does it allow to do so without adequate proof? I think not. That's the point I am trying to make here: There were no hard facts - apart from her not feeling well. Would it have been wise to quarantine her and keep her from traveling? in hindsight definitely. Is it justifiable to restrict one's individual freedom on such a weak basis as "she's not feeling well, but is below the temperature threshold established by experts"? Here you can IMHO lean either way. If you are more utilitarian, you might argue for it. If you are more about individual rights, you might argue against it.
