800 Passengers That Flew With Ebola-Infected Nurse Contacted

Frontier Airlines is reaching out to the passengers that traveled on the same flight as Amber Vinson, who came down with ebola after treating a patient in Texas. In the unfortunate case, those involved with the October 10th flight from Dallas to Cleveland on Frontier flight 1142 have been contacted in case of risk.

The expanded efforts came after officials said she may have shown symptoms of the virus four days before authorities first indicated. Ebola is contagious when someone is symptomatic.

Vinson traveled with a fever-- which was known before she flew.
