Was the second nurse infected with Ebola told not to fly?

(CNN) – A second nurse has been diagnosed with Ebola, after caring for Thomas Eric Duncan, the Liberian citizen who died of the disease last week. Amber Vinson cared for Duncan during his first three days at Texas Health Presbyterian Hospital, before he was diagnosed with the deadly disease.

Before the 29-year-old nurse was diagnosed on Tuesday, she had traveled to Cleveland, Ohio, to prepare for her upcoming wedding, flying aboard Frontier Airlines Flight 1143*.

Given that she was exposed to Ebola, why did Vinson fly? Was she not told she wasn't supposed to get on a commercial airline?

CNN's Elizabeth Cohen reports.
