ATLANTA — An American health-care worker who may have been infected with the Ebola virus in West Africa has arrived at a hospital near Atlanta.

Emory University Hospital spokeswoman Holly Korschun says the patient arrived around 5:45 a.m. Thursday.

Details about the patient were not released.

Emory houses a specialized isolation unit that handled four of the 10 Ebola patients previously treated in the U.S.

West Africa is suffering the worst Ebola outbreak in history, with more than 17,100 illnesses and at least 6,000 deaths this year. Six of those treated in the U.S. were Americans infected while providing medical aid there.
