Stunning news as the second Dallas nurse diagnosed with Ebola was on a flight with 132 passengers with an elevated temperature of 99.5 degrees the day before she checked into the hospital.
Here's what INSIDE EDITION knows: the nurse is named Amber Joy Vinson and she's is 29. Like Nina Pham, she was a member of the medical team who treated Patient Zero, Thomas Eric Duncan, at Texas Health Presbyterian Hospital.
She was on Frontier Airlines Flight 1143 from Cleveland to Dallas and landed at 8:16 Monday night. She started experiencing symptoms the next day and went to the hospital.
Toinette Parrilla, Cleveland's director of public health, said in a press conference, "She flew into Cleveland to prepare for her wedding. She came in to visit her mother."
Now, the airline is reaching out to all 132 passengers who were on the plane, advising them of the situation and asking each one to communicate directly with the CDC.
INSIDE EDITION's Diane McInerney spoke to ABC News' Chief Health and Medical Editor, Dr. Richard Besser.
Dr. Besser said, "She should have not gotten on that plane."
McInerney asked, "There were 132 passengers on this plane. Should they be worried?"
Dr. Besser said, "If I was on that plane, I would definitely be worried and would want additional information. Hopefully the information that they get will put their minds at some ease."
During a news conference Wednesday morning, when officials announced the news about the second nurse they said nothing about the Frontier Airlines flight, even though they knew.
How do we know? Frontier Airlines says they were contacted by the CDC at 1:00 in the morning, five hours before the news conference.
The Secretary of Health and Human Services went on all three network morning shows trying to calm public fears, but said nothing about the Frontier flight.
She said on the Today show, "I do have confidence in the CDC and Dr. Frieden."
Meanwhile, news of the flight is raising serious questions.
Ashleigh Banfield on CNN asked, "How could she have been flying?"
Dr. Besser told INSIDE EDITION, "You get Ebola from sharing body fluids. So, if she wasn't visibly sick, then, it would be very unlikely that she would put other passengers at risk. But, you don't want to have someone on an airplane where that is a possibility."
As for Amber Vinson, her stepfather said in a statement: "Right now she's doing OK. Her temperature is going down. We don't want to do a lot of talking about it now. She's OK. The main concern is for her to get better."
The plane was taken to a remote location where it was disinfected twice before being put back into service.
