New York City's health commissioner says a man who was admitted to Mount Sinai Medical Center with a high fever and gastrointestinal symptoms probably does not have Ebola.
Dr. Mary Bassett said Tuesday it's "highly unlikely" the man has Ebola even though he was recently in an area of West Africa where an outbreak has occurred.
Bassett said she would await test results from the U.S. Centers for Disease Control and Prevention.
The man was ill when he arrived in New York early Monday.
Officials at U.S. airports are watching travelers from Africa for flu-like symptoms that could be linked to Ebola.
The Ebola virus has sickened more than 1,600 people and killed nearly 900 since the outbreak erupted in West Africa.
It's spread through direct contact with bodily fluids.
