Ebola Prompts CDC to Monitor All Travelers Coming From Guinea, Liberia, Sierra Leone

All travelers from Ebola-affected countries to undergo 21-day monitoring.

If they do not report, officials will track them down, the CDC said.

They will need to take their temperature twice daily and answer several questions about their symptoms, according to the CDC.

The program will focus on the six states that see about 70 percent of the traffic from these regions: Georgia, Maryland, New Jersey, New York, Pennsylvania and Virginia.

Some states may monitor these travelers in person.
