CDC: 91 JFK travelers screened for Ebola

Since enhanced screening for Ebola began Saturday at New York's John F. Kennedy airport, 91 travelers were identified from West Africa, but none had symptoms, according to the Centers for Disease Control and Prevention.

"None of them had fever," CDC Director Tom Frieden said Monday. "Five of them were referred for additional evaluation by CDC. None were determined to have exposure to Ebola."

Enhanced screening with temperature checks and questionnaires for travelers from Liberia, Sierra Leone and Guinea will be in place by Thursday at four other U.S. airports: Washington's Dulles, Chicago's O'Hare, New Jersey's Newark and Atlanta's Hartsfield-Jackson airports.

"We anticipate having this in place at four additional airports in the U.S. and we will learn from that experience," Frieden said.

Those airports get 94% of the travelers from West Africa, who average about 150 daily, according to the administration.

But Frieden continued to oppose a travel ban for people from West Africa to visit the United States because getting health care workers and supplies to those countries is crucial in fighting the disease there. Ebola has infected 8,376 and killed 4,024 this year.

"If we do things that unintentionally make it harder to get that response in, to get supplies in, it's going to make it that much harder to stop the outbreak at the source," Frieden said.

CDC and Customs and Border Protection adopted the enhanced screening after a traveler, Thomas Eric Duncan, died Wednesday from the disease and a nurse who treated him has also become infected. Duncan arrived in Dallas from Liberia on Sept. 20 without symptoms
