( – Both Homeland Security Secretary Secretary Jeh Johnson and Centers for Disease Control and Prevention Director Tom Frieden said on Wednesday that 150 people a day arrive in the United States from Liberia, Sierra Leone or Guinea, the three West African countries that have been hit  by the Ebola virus.

“When somebody travels from one of those three West African countries, even through a transit point (in Europe), we know where they’re coming from. So we’re able to track this. And we know that on average it’s about 150 passengers a day,” Johnson told CNN’s Wolf Blitzer.

“The number of travelers is relatively small. We’re talking about 150 per day,” Frieden told a news conference on Wednesday. He announced that questionnaires and temperature checks will begin at five major U.S. airports that handle “95 percent of all the 150 travelers per day who arrive from these three countries.”

One hundred-fifty passengers a day from West Africa works out to more than a thousand a week (1,050), 4,500 a month, and 54,750 a year.

Given the 21-day incubation period for Ebola and the 150 people coming in each day, that means that at any given time there could be 21 x 150 people in the U.S. who could be asymptomatically incubating Ebola, and who are free to wander around the country.

That is 3,150 people who at any moment could become symptomatic anywhere in the country and start exposing people.

All passengers flying out of West African countries already undergo temperatures checks and answer questions about their contact with Ebola patients, but the screening doesn’t always work, as the case of Thomas Eric Duncan proves.

Duncan died of Ebola on Wednesday in Dallas, after coming to the U.S. from Liberia on Sept. 20. He reportedly failed to tell airport officials in Liberia about his contact with an Ebola patient, and he did not have a fever when he left that country.
