Amber Vinson, a nurse who fueled Ebola fears by flying to Cleveland after being infected by her dying patient in Dallas, is now virus-free, and was celebrated by her caregivers as courageous and passionate before getting out of the hospital on Tuesday.

Another nurse who was held for days against her will in a medical tent in New Jersey after volunteering in West Africa was in an ``undisclosed location'' in Maine, objecting to both states' Ebola quarantine rules as overly restrictive.

While world leaders appeal for more doctors and nurses on the front lines of the Ebola epidemic, health care workers in the United States are finding themselves on the defensive.

Lawyers now represent both Amber Vinson, who contracted the virus while caring for a Liberian visitor to Texas, and Kaci Hickox, who is challenging the mandatory quarantines some states have imposed on anyone who has come into contact with Ebola victims.
