nn_02tco_ebola_141015Federal health officials will begin tracking passengers who were on the plane Ebola-infected nurse Amber Vinson took from Dallas to Ohio on Oct. 10 — a date when she supposedly did not have symptoms and was not contagious. “We can’t rule out that she might have had the start of her illness on Friday,” Dr. Chris Braden of the Centers for Disease Control and Prevention said at a Friday afternoon briefing, citing new information developed by investigators tracing all of Vinson’s contacts. “This new information is saying we need to go back now to the flight she took on Friday the 10th and include them in our investigation of contacts.” The date that an Ebola patient starts showing symptoms is crucial because it is thought they can’t spread the disease before then.
