Texas officials said the nurse reported a fever on the morning of Oct.14 and was put in isolation 90 minutes later at Texas Health Presbyterian Hospital in Dallas. She is being transferred to Emory University Hospital in Atlanta, according to the Department of Health and Human Services.
ABC NEWS identified the woman as nurse Amber Vinson.
Frontier Airlines said the woman also flew on Frontier Airlines flight 1142 from Dallas Fort Worth to Cleveland on Oct. 10. Frontier says there were 152 people on that flight.
The nurse, 29, went to Akron, Ohio to visit family and prepare for a wedding.
While the CDC and Frontier Airlines said they are working to identify and contact customers who may traveled on Flight 1143, customers who traveled on either flight are being asked to contact the CDC at 1-800 CDC-INFO (1-800-232-4636).
As concerns about Vinson's travel spread, Kent State University said it has asked three employees who are relatives of the patient to remain at home and self-monitor for potential Ebola symptoms for 21 days under a CDC protocol.
Vincent did not visit the Kent State campus during her trip to Ohio, where she stayed with family members in nearby Summit County, university officials said. Asking the three employees to stay home was done "out of an abundance of caution," said Dr. Angela DeJulius, Kent State director of University Health Services.
The CDC and Frontier Airlines said the healthcare worker exhibited no signs or symptoms of illness while on Flight 1143, according to the crew.
"Individuals who are determined to be at any potential risk will be actively monitored," officials said.
Frontier said the plane was cleaned in Dallas Monday night, which is standard procedure. The plane returned to service Tuesday. It was cleaned again Tuesday night in Cleveland.
Frontier said it was notified at 1 a.m. MT Wednesday and took the plane out of service.
NewsNet5.com in Cleveland reported that the plane was grounded in Cleveland on Wednesday morning for decontamination. By Wednesday afternoon, the plane was back in the skies again, making its way to Denver.
However, 7NEWS has learned the plane made five additional trips after Vinson was dropped off in Dallas on Oct. 14. The plane also flew to Fort Lauderdale and Atlanta from Cleveland.
The preliminary test for the latest victim was run late Tuesday night at the state public health lab in Austin, officials said, with results being received around midnight. That test confirmed the woman has Ebola.
The CDC in Atlanta also planned to run tests on a separate specimen.
City workers in Dallas went to the woman's neighborhood early Wednesday morning to knock on doors and alert people to the news and to ask them to be alert for possible symptoms, according to Dr. Daniel Varga of Texas Health Resources.
They handed out flyers and later began robo calls to the area, Varga said.
Authorities have already begun decontamination efforts at the woman's apartment.
On the morning of Oct. 14, the second healthcare worker reported to the hospital with a low-grade fever and was isolated. The Centers for Disease Control and Prevention confirms that the second healthcare worker who tested positive last night for Ebola traveled by air Oct. 13, the day before she reported symptoms.
Because of the proximity in time between the evening flight and first report of illness the following morning, CDC is reaching out to passengers who flew on Frontier Airlines flight 1143 Cleveland to Dallas/Fort Worth Oct. 13.
CDC is asking all 132 passengers on Frontier Airlines flight 1143 Cleveland to Dallas/Fort Worth on October 13 (the flight route was Cleveland to Dallas Fort Worth and landed at 8:16 p.m. CT) to call 1 800-CDC INFO (1 800 232-4636). After 1 p.m. ET, public health professionals will begin interviewing passengers about the flight, answering their questions, and arranging follow up. Individuals who are determined to be at any potential risk will be actively monitored.
The healthcare worker exhibited no signs or symptoms of illness while on flight 1143, according to the crew. Frontier is working closely with CDC to identify and notify passengers who may have traveled on flight 1143 on Oct. 13. Passengers who may have traveled on flight 1143 should contact CDC at 1 800-CDC INFO (1 800 232-4636).
Frontier Airlines Statement:
“At approximately 1:00 a.m. MT on October 15, Frontier was notified by the CDC that a customer traveling on Frontier Airlines flight 1143 Cleveland to Dallas/Fort Worth on Oct. 13 has since tested positive for the Ebola virus. The flight landed in Dallas/Fort Worth at 8:16 p.m. local and remained overnight at the airport having completed its flying for the day at which point the aircraft received a thorough cleaning per our normal procedures which is consistent with CDC guidelines prior to returning to service the next day. It was also cleaned again in Cleveland last night. Previously the customer had traveled from Dallas Fort Worth to Cleveland on Frontier flight 1142 on October 10.
Customer exhibited no symptoms or sign of illness while on flight 1143, according to the crew. Frontier responded immediately upon notification from the CDC by removing the aircraft from service and is working closely with CDC to identify and contact customers who may traveled on flight 1143.
