A doctor who recently returned from West Africa has been quarantined at Bellevue Hospital and is currently undergoing tests to see whether or not he has been in infected with the Ebola virus.

The Manhattan doctor, who served with Doctors Without Borders, returned to New York from West Africa, according to CNN, and began experiencing fever, nausea, pain and fatigue on Wednesday. On Thursday morning he was taken to Bellevue, a hospital designated to handle Ebola cases.

CBS News reports the physician, who is in his early 30s, returned around 21 days ago from Ebola-stricken Guinea. The man quarantined himself when the symptoms appeared and a specialized EMS crew transported him to the hospital.

"As per the specific guidelines that Doctors Without Borders provides its staff on their return from Ebola assignments, the individual engaged in regular health monitoring and reported this development immediately," Doctors Without Borders spokesman Tim Shenk said in a statement.

The local CBS affiliate has indentified the doctor as Craig Spencer who lives on West 147th Street. Spencer allegedly went bowling in Williamsburg the previous night, taking an Uber car to and from the Brooklyn neighborhood.

However, city officials want to maintain calm and reassure citizens that the possible infection is being handled.

"The chances of the average New Yorker contracting Ebola are extremely slim," officials said in a statement. "Ebola is spread by directly touching the bodily fluids of an infected person. You cannot be infected simply be being near someone who has Ebola."

Ciity council representative, Mark Levine (D-7th), who represents Spencer's neighborhood reassured his constituents.

"I want to assure everyone in Northern Manhattan that City, State and Federal public health authorities are responding with the highest possible level of urgency and marshaling every resource at their disposal to respond to this possible case. I want to reiterate that this has not yet been confirmed as an Ebola case but every precaution is being taken as if it were," he said.

City officials say they are currently tracking anyone who may have come in contact with Spencer and say the Ebola test results are expected within 12 hours.
