New York's JFK airport starts Ebola screenings for travelers coming from affected nations

New York's John F. Kennedy International Airport has reportedly started health screenings for some travelers to help prevent the spread of Ebola even as the Centers for Disease Control and Prevention warned that nothing can "get the risk to zero."

As the screenings began on Saturday, the CDC made it clear that the move is not a mass event and only 150 travelers will receive screenings in a day, reported CNN.

Dr. Martin Cetron, director of the CDC's Division of Global Migration and Quarantine, warned that no matter how many procedures are put in place, the risk cannot be minimized to zero. He added that the move will just add an additional measure of security to the American public.

Under the procedure, passengers originating from Guinea, Liberia, and Sierra Leone will be subjected to the additional screening. Passengers will be required to get their temperature measured and answer questions about their health and possible exposure to Ebola.

Those suspected of possible Ebola exposure will be referred to a CDC public health officer for additional screening.

After the initial run at JFK, the screening is expected to be expanded to Washington-Dulles, Newark, Chicago's O'Hare International Airport and Hartsfield-Jackson International Airport in Atlanta on Thursday.

The five airports receive 94 percent of the travelers coming from the affected countries, the CDC said.
