(CNN) -- Screening could soon be increased at U.S. airports because of the Ebola outbreak, officials said Sunday.
"All options are on the table for further strengthening the screening process here in the U.S., and that includes trying to screen people coming in from Ebola-affected countries with temperature checks," a federal official said.
The source added: "It's not as easy as it sounds. There aren't that many direct flights from Ebola-affected countries to the U.S. anymore. Many passengers are arriving on connecting flights from other parts of the world, and then they come here, so that makes it more of a challenge."
