A battle of words broke out over the weekend between Kaci Hickox, who returned home from Ebola-ravaged West Africa only to be ordered into quarantine, and Republican governor Chris Christie. The nurse told CNN that her "basic human rights have been violated" and that Christie himself was responsible.

CDC officials stopped short of issuing nationwide quarantine rules, instead issuing new guidelines that set levels of risk for returning travelers - guidelines to help those states that are currently monitoring travel from West Africa.

But, should health care workers coming from West Africa be quarantined?

In an interview with CNN's Erin Burnett, Dr. Rick Sacra says a mandatory quarantine would be a 'disincentive' for people to travel to West Africa to treat Ebola patients.

The nurse in the middle of a national firestorm over Ebola quarantine rules is Ebola-free and left New Jersey for her home in Maine.

But Kaci Hickox was forced into quarantine by New Jersey governor Chris Christie after she returned from treating Ebola patients in Sierra Leone is not going home quietly. She's threatening to sue Christie and says he knows nothing about medicine.

Christie is not backing down and says he's not sorry.

"She needs to understand that the obligation of elected officials is to protect the public health of all the people and if that inconvenienced her for a period of time, that's what we need to do to protect the public," Christie says.

The governors of New York and New Jersey announced a mandatory quarantine for anyone returning from West Africa who had direct contact with an Ebola patient.

This comes as Dr. Craig Spencer, the first person diagnosed with Ebola in New York City, is now in stable condition. His fiancée and two other friends are all under quarantine.

Officials are now tracing all of Spencer's movements since he returned from treating Ebola patients in Guinea.

Jason Carroll is OutFront with the report.

A doctor who recently returned from Guinea has tested positive for Ebola - the first case of the deadly virus in New York City and the fourth diagnosed in the United States.

The doctor, identified as Craig Spencer, 33, came back from treating Ebola patients in Guinea on October 17 and developed a fever, nausea, pain and fatigue Thursday. He is isolated in stable condition at New York's Bellevue Hospital Center, one of the eight hospitals statewide that New York Gov.

Spencer, who is in intensive care, went for a jog, may have gone to a restaurant, traveled the city's subway system and went bowling before feeling ill, but authorities sought to assure an anxious public that the likelihood of him spreading the virus was low.

"We want to state at the outset there is no reason for New Yorkers to be alarmed," Mayor Bill de Blasio told reporters late Thursday.

There's no question Spencer was heroic -  he traveled to west Africa to treat Ebola patients. But many people are outraged that he traveled around the most populated city in America when he was feeling "sluggish."

As a doctor, should he have known better?
