Screening for the Ebola virus begins today at Chicago's O'Hare International Airport.
Customs and health officials will take temperatures of passengers from three West African countries. They will use no-touch thermometers to try to halt the spread of the Ebola virus that has killed thousands.
Customs officials say about 150 people travel daily from or through west African countries to the U-S. Almost all of them land in New York, Chicago, Newark, Atlanta or Washington, D.C.
