First Ebola Case Diagnosed in US Is ‘Critically Ill’

The first case of deadly Ebola diagnosed in the U.S. has been confirmed in Dallas, in a man who was traveling in Liberia and arrived in the U.S. on Sept. 20, the Centers for Disease Control and Prevention said today.

The man is being kept in isolation. He had no symptoms when he left Liberia, then began to show signs of the disease on Sept. 24, the CDC said today. He sought medical care on Sept. 26, was hospitalized two days later and is now critically ill, said Thomas Frieden, the director of the CDC.

Frieden said the agency was working to identify anybody who had contact with the man and tracking them down. “There is no doubt in my mind that we will stop it here,” he said at a press conference in Atlanta.

The CDC has a team of epidemiologists on the way to Texas now, he said. The team will follow anyone who has had contact with the man for 21 days. If they develop any symptoms, they’ll immediately be isolated, as will anyone who has had contact with them. The diagnosis was first confirmed by a Texas lab based on samples of the man’s blood, and confirmed by the CDC.
