Fear grew in New York City after Dr. Craig Spencer was rushed to Bellevue hospital on Thursday for a fever and was later diagnosed with Ebola. His fiancée, Morgan Dixon, was also quickly put into isolation.

Below is everything we know so far:

Spencer and his girlfriend live on West 147th Street in Harlem. The apartment has been sealed off.

Spencer is now being treated while in quarantine at Bellevue hospital. Dixon is quarantined at the same hospital.

Two of his friends who had been in contact with him are also quarantined in their homes. They don’t have any symptoms of the disease and neither does his girlfriend.

The days before he was diagnosed, Spencer took the subway (A, L and 1), an Uber car and visited the High Line. The night before he was diagnosed he went bowling at The Gutter in Brooklyn.

Spencer, 33, contracted the virus while helping Ebola patients in Guinea in West Africa as a Doctors Without Borders physician. He became the fourth person in the U.S. to be diagnosed, but the first in New York City.

He had no symptoms after returning to the U.S. until Thursday morning when he felt fatigue and nausea. He also had a fever of 100.3 degrees.

"He's a nice guy, and kind of, wow," his neighbor, John Reston, told the New York Times. "He's a nice guy, friendly, jovial. And I know he's really dedicated to his work. That he's with Doctors Without Borders says who he is." 

The Michigan native and Dixon, who met at Henan University in China, plan to marry next fall in Detroit.

Spencer is currently an assistant professor of medicine at Columbia University and fellow in international emergency medicine at New York-Presbyterian Hospital. He hasn’t worked since he returned from the trip on Oct. 17. New reports state that he's in "stable condition."

Dixon currently works as a Development Associate at The Hope Program, according to her Linkedin. The company works to help homeless and welfare-dependent adults develop careers.She's also dedicated her time as a volunteer in humanitarian missions overseas.

Dixon's family released a statement following Spencer's diagnosis and said they are hoping for his full recovery.

"The Dixon family is asking for your thoughts and prayers for Craig Spencer and his fiancee, our daughter, Morgan Dixon," the family said. "We have confidence in the medical care Craig is receiving and we are hoping for a complete recovery."

The family added: "We are very proud of and support the work Craig has been involved with throughout this career."
