The head of the CDC told CNBC on Monday that while Ebola continues to spread in West Africa there's a possibility that the U.S. will see another patient with the disease like the one in Dallas.
Dr. Thomas Frieden, who plans to brief President Barack Obama later Monday, refused to say on "Squawk Box" whether flights into the United States from the nations being hardest hit by the outbreak should be halted. He did say that we shouldn't do anything that would make containing the disease there more difficult. He used the example of aid workers trying to get into the affected zone being held up by canceled flights.
The World Health Organization has not placed any restrictions on travel and has encouraged airlines to keep flying to the worst-hit countries. British Airways and other airlines have suspended some flights.
"Right now we've made sure there's a rigorous exit screening process," Frieden said. The director of the Centers for Disease Control and Prevention added that the best way to keep Americans safe from Ebola is to stop it at its source. He reported progress on containing the disease in Africa.
