Doctors Without Borders physician, Craig Spencer, has been diagnosed with Ebola. Spencer is the first New York resident to test positive for the virus.

According to CNN, Dr. Spencer was treating patients in Guinea up until October 12 and left Africa on October 14th making his way through Europe. He returned to New York's JFK Airport on the 17th and did not begin to show symptoms until Thursday. During the time of his return, Spencer went for a run, rode the subway and used the popular car service, Uber.

As a precaution, officials have planned to place his two friends and fiancee in quarantine to be monitored. The car driver will not be examined since he had little contact with the doctor. Spencer is currently being held at New York's Bellevue Hospital.

In a press conference, NYC's health commissioner Dr. Mary Travis Bassett detailed Spencer's whereabouts before he was checked into the hospital. Bassett revealed that the doctor also went to The Gutter, a bowling alley located in Brooklyn before his symptoms kicked in. The alley is now closed.

She also added that the city's residents have little to worry about since the doctor contacted officials as soon as he felt symptoms of the virus - fever, nausea, pain and fatigue.

"At the time that the doctor was on the subway he did not have fever ... he was not symptomatic," she said.

Over 5,000 people have died from the virus in Liberia, Guinea and Sierra Leone.

Thomas Eric Duncan was the first U.S citizen to die of the virus when he arrived in Texas earlier this month.
