Federal officials have announced a new Ebola screening policy at five major airports nationwide. The measures will apply for passengers arriving from West Africa at New York City’s John F. Kennedy starting this weekend, followed later by Newark Liberty, Washington Dulles, Chicago O’Hare and Hartsfield-Jackson Atlanta. Tom Frieden, director of the Centers for Disease Control and Prevention, unveiled the screening program on Wednesday.

Tom Frieden: “These five airports represent about 94, nearly 95 percent of all of the 150 travelers per day who arrive from these three countries. The Department of Homeland Security, CBP, Customs and Border Protection, will be implementing a new detailed questionnaire as well as temperature taking and providing information to each traveler. What we’re doing is putting in additional protection. We’ve been very clear that as long as Ebola continues to spread in Africa, we can’t make the risk zero here. We wish we could.”
