physician with Doctors Without Borders who returned to New York City from West Africa has tested positive for Ebola, the New York Times said on Thursday.

The doctor was identified as Craig Spencer, who was working for the humanitarian organization in Guinea, one of three West African nations hardest hit by Ebola.

Spencer, 33, developed a fever and gastrointestinal symptoms and notified Doctors Without Borders on Thursday morning, the organization said in a statement.

Spencer was transported to Bellevue Hospital from his Manhattan apartment by a specially trained team wearing protective gear, the New York City Department of Health and Mental Hygiene said in a statement.

He tested positive for Ebola, the Times said, making him the city's first diagnosed case.

Spencer's Facebook page, which included a photo of him clad in protective gear, said he went to Guinea around Sept. 18 and then flew to Brussels on Oct. 16.

He has specialized in international emergency medicine at Columbia University-New York Presbyterian Hospital in New York City since 2011, according to his profile on the LinkedIn career website.

Columbia in a statement said he has not been to work nor seen any patients since his return.
