A West African passenger who arrived at Newark Liberty International Airport yesterday has been hospitalized after officials discovered he had a fever, on the same day that the Department of Homeland Security announced enhanced Ebola screenings at JFK and Newark Airports.

The unidentified passenger flew into Newark on a United Airlines flight from Brussels, though his travel plans originated in Liberia. Medical workers took his temperature using a no-touch thermometer, and he was "identified as reporting symptoms or having a potential exposure to Ebola," according to a CDC spokesperson. He was transported to University Hospital in New Jersey, where he is in isolation, and NBC reports he is being evaluated "as if he has Ebola," though his condition has not been determined.

CDC officials say they will contact other passengers on yesterday's flight if test results come back positive for Ebola.

Newark Airport is one of five airports in the United States that has been designated by the DHS for enhanced Ebola screenings—passengers whose travel plans originate in Sierra Leone, Liberia and Guinea cannot enter the country until they are cleared by medical workers. JFK Airport, along with Chicago’s O’Hare International Airport, Dulles International Airport in Virginia and Hartsfield Jackson International Airport in Atlanta, will also utilize the screenings.
