CDC: Every traveler coming from Ebola nations will be monitored for 21 days

WASHINGTON -- Significantly expanding their vigilance, federal health officials said Wednesday that they would begin monitoring all travelers - even Americans - who come to the U.S. from Ebola-stricken West African nations for 21 days.

Dr. Tom Frieden, director of the Centers for Disease Control and Prevention, said the expanded screening would begin Monday in six states - New York, Pennsylvania, Maryland, Virginia, New York and Georgia.

He said the new system would further protect Americans. "The bottom line is that we have to keep our guard against Ebola," he said.

Travelers from those countries will be given information cards and a thermometer and be required to make daily check-ins with state or local health officials to report their status. He said the check-ins could be in person, by telephone, Skype or Facetime or through employers - CDC was consulting with the state and local officials to help them work that out.

The travelers would be required to report any travel plans.

Frieden said if they don't cooperate, they would be immediately called in.

Meanwhile, Ron Klain stepped up to his new role as Ebola "czar" Wednesday morning.

The White House and those close to Klain told CBS News chief White House correspondent Major Garrett that they see his role as primarily internal and decidedly lacking in media sizzle. He's said to be the behind-the-scenes director making sure decisions are tracked and carried out quickly, pulling all the various points of view together without distraction or indecisiveness.

Klain will work in the West Wing and have regular access to top aides. He's expected to meet frequently with National Security Adviser Susan Rice and White House Homeland Security Adviser Lisa Monaco. As has been reported previously, Klain will be paid.

Klain will represent Mr. Obama and have direct access for any next steps.
