The first nurse in the U.S. to contract Ebola, Nina Pham, arrives at National Institutes of Health (NIH) in Maryland.
The 26-year-old was transferred by a specially-equipped medical jet and will be treated in an isolation unit.
Pham fell ill after caring for Liberian Thomas Eric Duncan who died from the disease last week at the Texas Health Presbyterian Hospital.
Concerns in the U.S. have intensified after two Texas nurses who cared for a dying Liberian patient contracted the virus that has killed nearly 4,500 people.
