UPDATE 2:50p ET: The second nurse who contracted Ebola at a Dallas hospital has been identified as 29-year-old Amber Vinson.

Fox News reported that Vinson will be transported to Emory University Hospital in Atlanta for treatment.

The Centers for Disease Control and Prevention (CDC) has announced that the second Dallas healthcare worker to contract Ebola flew on a Frontier Airlines flight on Monday, the day before she reported a fever and was diagnosed with the deadly virus.

Texas health officials had previously announced that she was exposed to Ebola while she was one of more than 70 people who treated Liberian national Thomas Eric Duncan, the first man to be diagnosed with Ebola in the U.S., who died a week ago.

Although this new patient displayed no symptoms during Frontier Airlines flight 1143 from Cleveland to Dallas/Fort Worth on Monday, landing at approximately 8:16p CT, the CDC is asking all 132 passengers that were onboard to call 1 800-CDC INFO (1 800-232-4636).

The CDC says the woman should not have flown. 

On "Happening Now" today, Dr. William Schaffner, a Vanderbilt University infectious disease expert, said he doesn't believe these passengers have anything to worry about. 

He maintained that a passenger would had to have had contact with the woman's blood or bodily fluids in order to become infected. 

"They're going to be alright," said Schaffner, who downplayed fears that the virus can spread through the air or in other ways. 

"It's not like the flu. ... [Ebola is the] same old virus being transmitted in the same old way," he said, assuring that "there will not be widespread Ebola in the United States."

He also conceded there were "major glitches" within the hospital where the two health care workers got infected.
