On March 13, an American volunteer health care worker in Sierra Leone who tested positive for Ebola virus returned to the U.S. by medevac and was admitted to the NIH Clinical Center for care and treatment. As a result of this case, CDC is conducting contact tracing of individuals in Sierra Leone, including several other American citizens, who may have had potential exposure to this index patient. At this time, none of these individuals have tested positive for Ebola. These individuals are volunteers in the Ebola response and are currently being monitored in Sierra Leone. Out of an abundance of caution, CDC and the State Department are developing contingency plans for returning those Americans with potential exposure to the U.S. by non-commercial air transport. Those individuals will voluntarily self-isolate and be under direct active monitoring for the 21-day incubation period.
One of these American citizens had potential exposure to the individual being treated at NIH and is currently being transported via charter to the Atlanta area to be close to Emory University Hospital. The individual has not shown symptoms of Ebola and has not been diagnosed with Ebola. Upon arrival in Atlanta, the individual will voluntarily self-isolate and be under direct active monitoring for the 21-day incubation period.
