CDC: New Ebola patient had 3 contacts before isolation

Three people had contact with the latest Ebola patient before she was isolated, said Dr. Tom Frieden, director of the Centers for Disease Control and Prevention in a phone briefing. They have not identified anyone else who has exhibited symptoms. However, this can change from "minute to minute, hour to hour," he said.

The latest Ebola patient, who is the second healthcare worker in Texas to test positive for the disease, will be transported to Emory University Hospital.

In a statement, Texas Health Presbyterian Hospital confirmed that the possibility of a transfer is being discussed. The hospital is consulting with Emory University Hospital in Atlanta and other health officials.

"We will provide new information as decisions are made," the hospital said in the release.

The second healthcare worker who has contracted Ebola should not have traveled and violated CDC guidelines, said Dr. Frieden. The fact that the worker had high exposure to the deceased patient Thomas Eric Duncan should have been another indication to prohibit travel, he said. From now on, people being monitored will not be allowed to board a commercial flight.

Sylvia Mathews Burwell, secretary of the Department of Health and Human Services, said that the CDC would send go-teams to hospitals that find new Ebola cases to ensure rapid response.

"We know how to stop this," said Burwell.

A second Dallas health-care worker has tested positive for Ebola, officials confirmed Wednesday, as they also asked 132 people who flew with that infected woman on a Frontier Airlines flight from Cleveland to Dallas on Monday to call the federal Centers for Disease Control.

The woman's employer, Texas Health Presbyterian, is facing renewed criticism for its handling of Duncan's case, which also led to the infection of nurse Nina Pham, 26, who is also in isolation at the hospital.
