WASHINGTON (AP) — Everyone coming to the United States from the three West African countries at the center of the Ebola outbreak will now be screened for the deadly disease at one of five airports, the Homeland Security Department said Tuesday.

Earlier this month, Customs and Border Protection officers at New York’s Kennedy, Newark Liberty, Washington’s Dulles, Chicago’s O’Hare and Hartsfield-Jackson Atlanta airports started screening people arriving from West Africa. The screening includes using no-touch thermometers to determine if travelers have a temperature, one symptom of a possible Ebola infection. The Centers for Disease Control and Prevention is also working with DHS on the screening.
