Officials: No known Ebola cases in Ohio

"In addition, Ohio is working with the airline to identify individuals on her return flight to Dallas," the department said through a news release.

"As of right now we do not have a case of Ebola in Ohio," said Mary DiOrio, state epidemiologist, in a conference call with the media.

DiOrio could not say exactly where the woman may have visited while she was in Akron. "The investigation is ongoing," she said.

The incubation period between exposure to Ebola and developing symptoms is two to 21 days, she said, with an average of 8 to 10 days.
