10 Americans Possibly Exposed to Ebola Returning to US

— -- The Centers for Disease Control and Prevention is bringing back 10 additional Americans from Sierra Leone who were possibly exposed to Ebola.

None of the 10 people are sick, the CDC said today, but they all had contact with an American who tested positive for Ebola and was admitted to the National Institutes of Health earlier this week.

"As a result of CDC's ongoing investigation, CDC and the State Department are facilitating the return of additional American citizens who had potential exposure to the index patient or exposures similar to those that resulted in the infection of the index patient. Currently, none of these individuals have been identified as having Ebola virus disease," the CDC said in a statement.

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.
