Officials say Vinson was a passenger on Frontier Airlines Flight 1143, which flew from Cleveland, Ohio to Dallas-Fort Worth International Airport on Monday.
It was later confirmed that the CDC gave Vinson permission to get on the plane because she was showing no other symptoms of the virus, and her temperature didn’t reach the threshold of 100.4 degrees.
The CDC announced during a teleconference Wednesday afternoon that Vinson was stable would be moved to a critical care facility at Emory University Hospital in Atlanta.
