A man who visited West Africa last month and is at a New York City hospital being tested for possible Ebola likely doesn’t have it.

A doctor at Mount Sinai Medical Center in Manhattan says “odds are” it’s not Ebola. Dr. Jeremy Boal says he hopes for a definitive answer in the next day or two.

The hospital says the patient had a high fever and gastrointestinal symptoms when he went in Monday. It placed him in isolation.

The Ebola virus causes a hemorrhagic fever that has sickened more than 1,600 people, killing nearly 900 mostly in Liberia, Guinea and Sierra Leone.

A spokesman for the Centers for Disease Control and Prevention says at least three Americans have been tested in the U.S and all tested negative.
