EBOLA – Dallas, Texas

Dallas Mayor Mike Rawlings has activated a city emergency management center after a patient was confirmed with the first case of Ebola diagnosed in the U.S.

Rawlings said Wednesday that city officials are cooperating with the Centers for Disease Control and Prevention to determine who’s been in contact with the man.

Medical experts on Tuesday confirmed the diagnosis of the man who recently traveled from Liberia to Dallas. The critically ill patient, whose name wasn’t released, has been in isolation at Texas Health Presbyterian Hospital since Sunday.

Officials have not made public where the man was staying in Dallas before he sought medical care.

Ebola is believed to have sickened more than 6,500 people in West Africa. More than 3,000 deaths have been linked to the disease.
