At least 10 U.S. aid workers who may have been exposed to the Ebola virus in Sierra Leone are being evacuated to the United States.
U.S. officials said Saturday that the individuals would be housed near the University of Nebraska Medical Center, the National Institutes of Health in Maryland, or Emory University Hospital in Atlanta. All three have been used to treat American Ebola patients in the past.
On Friday, a U.S. health care worker who tested positive for Ebola while in Sierra Leone arrived at the NIH for treatment.
None of the 10 aid workers has developed symptoms of Ebola.
The deadly virus has killed more than 10,000 people in the West African nations of Sierra Leone, Liberia and Guinea. At least 24,340 people have been infected with Ebola since the West African outbreak began in December 2013.
