Officials at Texas Health

Authorities with the Centers for Disease Control revealed the finding late on Tuesday, two days after the unidentified patient was admitted to a Dallas hospital with suspicious symptoms. Officials at Texas Health Presbyterian Hospital Dallas put the man into “strict isolation” and sent a blood specimen to state and federal labs for testing. Both came back positive for the deadly disease, which has killed more than 3,000 people in Africa this year. According to the World Health Organization, there have been more than 6,500 Ebola cases confirmed in Africa, with Guinea, Liberia and Sierra Leone among the hardest hit. “The patient was visiting family members and staying with family members who live in this country,” Dr. Thomas Frieden, CDC director, said at the news conference. A press release announcing the activation of the City of Dallas' Emergency Operations Center described the patient as having “moved to Dallas from Liberia a week ago.”
