CDC continues to investigate potential Ebola exposure among individuals in Sierra Leone, including several American citizens, following the identification of an American volunteer healthcare worker in Sierra Leone who tested positive for Ebola virus. That healthcare worker returned to the U.S. by medevac and was admitted to the NIH Clinical Center on March 13th for care and treatment.

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.

Individuals will be transported to the U.S. by non-commercial air transport and will be near the University of Nebraska Medical Center, the National Institutes of Health, or Emory University Hospital.

Individuals will follow CDC's recommended monitoring and movement guidelines, including direct active monitoring and, as appropriate, voluntary self isolation during the 21-day incubation period. In the event an individual shows symptoms, they will be transported following protocol to an Ebola treatment center for evaluation and care.
