NEW YORK (CBSNewYork/AP) – A patient at Mount Sinai Hospital was under treatment Monday afternoon, after being tested following a trip to a country where the Ebola virus is present, the hospital said in a statement.

As CBS 2’s Tracee Carrasco reported, the man arrived at the East Harlem medical center’s emergency room early Monday morning with high fever and gastrointestinal symptoms. The man told doctors he had recently traveled to a West African country where Ebola has been reported, the hospital said.

The man was placed into “strict isolation” within seven minutes of his arrival, and was undergoing various tests to determine the cause of the symptoms late Monday, the hospital said.

“The patient was promptly isolated and placed in a strict isolation facility at Mount Sinai, such that we could protect the patient and also any staff and other patients in the facility and all visitors,” said Mount Sinai Hospital President and Chief Operating Officer Dr. David Reich. “We are very confident that our work with the federal, state and local authorities will lead to a prompt evaluation of this patient, and that we’ll be able to hopefully find a more common cause of fever and the other symptoms that this patient has.”

At a news conference early Monday evening, Mount Sinai Chief Medical Officer Dr. Jeremy Boal said it was not likely that the patient was suffering from Ebola.

“The first thing that we’d like to stress is that odds are this is not Ebola,” Boal said. “It’s much more likely that it’s a much more common condition, and we’re ruling those things out as well.”

He said specimens have been sent to the Centers for Disease Control, and hospital officials hope to identify the disease in 24 to 48 hours.

Reich said officials do not feel it necessary to do testing on anyone who has come in contact with the patient, 1010 WINS’ Al Jones reported.

Boal and Reich declined to release information on the patient.
