Vison, a nurse at Texas Health Presbyterian Hospital Dallas, where Duncan was being treated and later died, flew to Cleveland on Friday to help plan her wedding. She returned to Dallas on Monday. She called health officials before her flight on Monday, reporting a minor fever. But the Center for Disease Control and Prevention told her it was okay to get on the plane.
Because she may have been sick earlier than officials believed, the CDC is expanding their investigation to people the 29-year-old nurse may have come into contact with over the weekend. Included are passengers who were on her flight to Cleveland, Fox 8 Cleveland reported.
