Amber Joy Vinson, the third person to have contracted the Ebola disease in the U.S., has been declared virus-free. Her fellow worker Nina Pham's condition has been upgraded to "good." As the two health care workers further recuperate and regain their strength, the virus has moved from Dallas to New York.

In a statement, Vinson's mother, Debra Berry, said nurse Amber has "been approved for transfer from isolation." Saying they are well aware that the nurse still has to undergo further treatment to be entirely rid of the virus, Berry said the transfer has been well received as a positive one by the family. "These latest developments have truly answered prayers and bring our family one step closer to reuniting with her at home," Berry added. The family didn't say when nurse Vinson will be released by the Emory University Hospital. The nurse remains under treatment within Emory's Serious Communicable Diseases Unit, the family said.

Vinson, along with Nina Pham, works for Texas Health Presbyterian Hospital. The two were among those who cared for Thomas Eric Duncan, the first Ebola patient in the U.S. on Oct. 14, Vinson came down with a fever. Even before tests confirmed she had contracted the Ebola virus, she was immediately taken into isolation at the Texas Health Presbyterian Hospital. Later on Wednesday, she was transferred to Emory.

Nina Pham was diagnosed with Ebola Oct. 12. On Thursday night, she was transferred to the National Institutes of Health (NIH) in Bethesda, Maryland. It was there that her condition was reported to have improved from fair to good as of Tuesday.

"We grieve for Nina Pham and for Amber and their families," Betsy Price, Fort Worth Mayor, was quoted by the local WFAA radio. The religious communities at Fort Worth held a vigil Wednesday night to pray for their well-being. "Both of them are going to be fine," Price said at the vigil. "We believe there will be more good news coming," Rev. Lance McCune added.

Meantime, the Ebola virus, an infection predominant only in west Africa, not only has made its stamp in Dallas, but has also reached New York City.

Craig Spencer, a member of Doctors Without Borders and who just recently came home after treating Ebola patients in West Africa, has been confirmed positive for the virus. Spencer reported Thursday experiencing fever and gastrointestinal symptoms. He was rushed to the Bellevue Hospital Center on the same day and immediately placed on isolation. Apart from tests verifying the presence of the Ebola virus in his body, he likewise underwent tests for more common illnesses like Malaria.

Bill de Blasio, New York City Mayor, immediately took to the press to control possible pandemonium that could erupt in the city following the latest development. "We want to state at the outset that New Yorkers have no reason to be alarmed," the AP quoted de Blasio. "New Yorkers who have not been exposed are not at all at risk."

Medical authorities are now tracking everyone Spencer might have gotten into contact with the past several days.
