The patient was admitted to the NIH Clinical Center on March 13 after a flight from West Africa aboard a chartered plane equipped with an isolation unit. The person’s name has not been released, but the Boston-based aid group Partners in Health has said the patient is a clinician who was working for the organization in West Africa.
NIH also treated nurse Nina Pham, who in September became the first American infected by Ebola on American soil. She was part of the team that treated a Liberian infected by the virus at a hospital in Dallas.
In the current outbreak, the Centers for Disease Control and Prevention and the State Department have flown 17 American citizens who had possible exposure to Ebola back to the United States. They show no signs of the infection but were still being monitored last week.
A Sierra Leonean national who worked at the same Ebola treatment center as the NIH patient tested positive for Ebola and is being treated in Sierra Leone. An additional 23 American volunteers who may have had similar exposures while in Sierra Leone have returned to the United States and already were being monitored because they are health-care workers.
