Emory Hospital officials announced today that they they have received a third Ebola patient for treatment at the hospital’s specially-designed Isolation Unit.

The news comes three weeks after the hospital released two Ebola virus patients who became infected while caring for patients in West Africa. Hospital officials have not identified the third patient.

“Emory University Hospital physicians, nurses and staff are highly trained in the specific and unique protocols and procedures necessary to treat and care for this type of patient,” the hospital said in a statement.

Earlier this month, the Centers for Disease Control warned that the Ebola epidemic in West Africa is “outpacing (the) current response.”

“The window of opportunity to stop Ebola from spreading widely throughout Africa and becoming a global threat for years to come is closing, but it is not yet closed,” CDC Director Tom Frieden said via press release. “If the world takes the immediate steps– which are direct requests from the front lines of the outbreak and the Presidents of each country – we can still turn this around.”
