From The Atlantic:

It’s not a outright Ebola travel ban, but the federal government is limiting the ways in which passengers from West Africa can enter the United States. The Department of Homeland Security on Tuesday announced that travelers from Liberia, Sierra Leone, and Guinea—the three countries at the center of the Ebola outbreak—will have to fly into the U.S. through one of five airports: New York’s JFK, Washington D.C.’s Dulles, Atlanta, Chicago O’Hare, and Newark, N.J. Those are the same five airports where officials began secondary screenings of travelers from those countries earlier this month.
