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.

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?
Miguel Marquez has the report.
The family of Amber Vinson, the second Dallas nurse to contract Ebola, have hired a high-profile defense attorney.
They say it is "untrue and hurtful" that Vinson ignored the agency's protocols and put others at risk by taking commercial flights between Dallas and Cleveland.
They insist that Vinson did everything properly:
-Consulting Texas health officials and the CDC repeatedly throughout her trip
-Clearing her flight to Cleveland with hospital and CDC officials.
-Asking if she should fly back to Dallas
Vinson also spoke with Texas health officials and asked if she should fly back to Dallas immediately after learning her colleague had Ebola. She was told that was unnecessary.
Still, the next day she decided to fly back, calling health officials three separate times to report her temperature, and was cleared to fly each time.

As the World Health Organization warns the hot zone of West Africa could see 10,000 new Ebola cases per week, researchers are in a race against the clock to find a miracle drug to stop the epidemic.

(CNN) – Under fire in the wake of Ebola cases involving two nurses and monitoring for dozens of people, the Centers for Disease Control and Prevention issued updated Ebola guidelines Monday, focusing on better protecting health care workers. "Any infection is unacceptable," CDC Director Tom Frieden told reporters. He stressed the importance of more training and supervision.
