A female nurse who had "extensive" contact with the American index case who died last week has tested positive to Ebola Virus. This patient was not among those previously under surveillance and the authorities believe there was a breach of relevant protocols in this case.

"At some point, there was a breach in protocol, and that breach in protocol resulted in this infection," Dr. Tom Frieden, director of the Centers for Disease Control and Prevention in Atlanta, said at a news conference Sunday on a patient in Dallas who has preliminarily tested positive for the Ebola virus.


A female nurse at Texas Health Presbyterian Hospital in Dallas has tested positive for Ebola after a preliminary test, officials said.

Confirmatory testing will be conducted Sunday by the Centers for Disease Control and Prevention in Atlanta. Test results are expected to be announced later in the day.

The patient is a female nurse, an official who is familiar with this case told CNN.

She helped care for Thomas Eric Duncan, the first person ever diagnosed with Ebola in the United States, Texas Health Resources chief clinical officer Dan Varga said. Duncan died Wednesday.

The nurse is in stable condition, Varga said.

The nurse was involved in Duncan's second visit to the hospital, when he was admitted for treatment, and was wearing protective gear as prescribed by the CDC: gown, gloves, mask and shield, Varga said.

The official familiar with the case told CNN that the CDC will investigate to see if guidelines were followed properly.

"The CDC is looking very carefully around the circumstances of this patient's infection and will look to see if there were any breaches and, if so, what those were," the official said.

A "close contact" of the nurse has been "proactively" placed in isolation, Varga said.

The hazardous materials unit of the Dallas Fire Department has cleaned up and decontaminated the public areas of her apartment complex, Mayor Mike Rawlings said. Police are keeping people out of the area and are talking to residents nearby.

"We have knocked on every door on that block," the mayor said.

Hazardous materials units have also cleaned out the nurse's car and will work on her apartment Sunday.

Case was anticipated

"We knew a second case could be a reality, and we've been preparing for this possibility," Dr. David Lakey, commissioner of the Texas Department of State Health Services, said in a statement Sunday morning.

"We are broadening our team in Dallas and working with extreme diligence to prevent further spread."

The nurse reported a low-grade fever Friday night and was isolated, the health department said. The preliminary test result came in late Saturday.

If confirmed by the CDC, the nurse's case would mark the first known transmission of Ebola in the United States and the second-ever diagnosis in the country.

A White House official told CNN that Homeland Security Adviser Lisa Monaco briefed President Obama on the second Dallas Ebola case.

CDC corroboration expected

David Sanders, associate professor of biological sciences at Purdue University, said he thinks the CDC testing will probably support the preliminary results.

"It sounds likely that it's positive, and it's going to stay positive."

The news that a health care worker might have the disease is not completely unexpected, an infectious disease specialist told CNN's "New Day."

"I think we've always expected that there may be another individual who will come down with the Ebola from the transmission of this one particular person, and we always felt that it was going to likely be one of his close contacts or one of the health care workers, because that's the way this virus works," Dr. Frank Esper said.

Esper said Texas officials have been keeping a close eye on people who had contact with Duncan.

"I will tell you that the fact that we identified this individual so quickly is actually to me a sign that the system is working," he added.

Globally, the disease has wrought catastrophic consequences.

The World Health Organization estimates more than 8,300 people have contracted Ebola during this year's outbreak. Of those, more than 4,000 have died.

Ebola not very infectious

Ebola is actually very difficult to catch. People are at risk if they come into very close contact with the blood, saliva, sweat, feces, semen, vomit or soiled clothing of an Ebola patient, or if they travel to affected areas in West Africa and come into contact with someone who has Ebola.

Those stricken with Ebola suffer ghastly symptoms, including vomiting, diarrhea, muscle pain, fever and unexplained bleeding.

Three countries -- Sierra Leone, Guinea and Liberia -- have been hardest hit. And many of those who care for the ill have also come down with the disease.

The World Health Organization estimates at least 416 health care workers have contracted Ebola, and at least 233 have died.

In Liberia, health care workers are threatening to strike if their work conditions don't improve.

The first infection outside of Africa happened in a nurse's aide in Spain, Teresa Romero Ramos. She became sick after she helped treat an Ebola-stricken Spanish missionary.

Her case has prompted questions from fellow medical professionals about whether they are properly equipped to safely treat Ebola patients.

Spanish Ebola patient's condition worsens, doctor says

Another search begins

For weeks, health officials have been monitoring those who had contact with Duncan before he was hospitalized and isolated.

Duncan left Liberia on September 19 and arrived in Dallas on September 20. Four days later, he began feeling ill; the following night, he went to Texas Health Presbyterian Hospital.

But despite telling a hospital worker that he had arrived from Liberia, Duncan was sent home with antibiotics. He returned a few days later and tested positive for Ebola.

And now, the search begins for all the contacts whom the nurse came in contact with.

"We need a whole new crew of people to do contact tracing," said Elizabeth Cohen, CNN senior medical correspondent.

Because Ebola's incubation period can last up to 21 days, the health nurse's contacts will have to be monitored for three weeks.

The Texas health department said officials have interviewed the patient and are identifying any contacts or potential exposures.

"This is not an easy thing," Cohen said. "Keeping track of large numbers of people, taking their temperature twice a day, making sure they don't ... leave town, all of that is a lot of work."
