Possible Ebola patient arrives at Atlanta hospital

Emory University Hospital in Atlanta is monitoring an American health care worker who may have contracted the deadly Ebola virus in West Africa, the facility said Thursday.

The hospital, one of 35 across the nation designated as an Ebola treatment center, first tweeted late Monday that the patient would be monitored there.

"As anticipated, an American health care worker from West Africa who may have been exposed to the Ebola virus has been transferred to Emory University Hospital's Serious Communicable Diseases Unit for testing and observation to see if an infection has been acquired," the hospital said in a statement.

The hospital said the patient arrived from an unnamed West African nation early Thursday on a specially equipped Phoenix Air jet. It declined to provide further information "out of respect for patient privacy and in accordance with the patient's wishes."

Four of the 10 Ebola patients treated in the U.S. this year have been admitted to Emory at some point in their illness.

A brutal Ebola outbreak in West Africa, centered in Liberia, Guinea and Sierra Leone, has killed more than 6,000 people. Six of those treated in the U.S. were Americans infected while providing medical aid there. Two people have died of the disease in U.S. hospitals.
