10 Americans Possibly Exposed to Ebola Returning to US

None of the 10 Americans are sick with the deadly disease, the CDC said.

The Americans will not travel commercially and will be near the University of Nebraska Medical Center, the National Institutes of Health or Emory University Hospital, the CDC added. Four of the 10 patients will be quarantined at Nebraska's hospital for observation, Nebraska Medicine said.

Earlier this week, a U.S. worker tested positive for Ebola and was admitted to the NIH Clinical Center Special Clinical Studies Unit in Maryland.

On Friday, another worker was transported near Emory to be monitored.
