FORT KENT, Maine (AP) — Maine health officials have asked a court to limit the movements of nurse Kaci Hickox, who defied a voluntary quarantine for medical workers who have treated Ebola patients.

Officials filed documents Thursday, following through with a threat to try to isolate her.

A judge signed a temporary order Thursday limiting Hickox's movement until a further court order expected Friday. For now, police are monitoring Hickox and her public interactions but cannot detain her.

Hickox, who treated Ebola patients in Sierra Leone, says confinement violates her rights. She says that she has no symptoms and poses no risk to the public.

The state is seeking to limit her travel, keep her out of public places, and require a 3-foot buffer if she comes into contact with people.
