A 46-year-old Ohio woman is being tested for the Ebola virus after recently traveling to a country affected by the outbreak, a local NBC station reported.
The woman is in medical isolation with a "potential case" of the deadly disease while her sample is sent to federal health officials for analysis, the article stated.
The woman's name, symptoms and previous travel itinerary were not identified. Columbus Public Health Department officials said she was "doing well."
The report was the second in less than 24 hours identifying a potential Ebola patient in the United States.
A New York City man is being treated at Mount Sinai Hospital for Ebola-like symptoms while awaiting the results of a diagnostic test. Officials said he was unlikely to have the disease and predicted a string of false alarms.
Nevertheless, the cases highlight the scant possibility that a traveler could bring the Ebola virus undetected into the United States.
Two Americans are currently being treated for the disease at Emory University in Atlanta. They contracted Ebola in Liberia and left the country on medical transport flights.
For travelers who might be carrying the virus, U.S. and international officials are relying on a variety of safeguards, including screenings at West African airports and quarantine stations in the United States.
The Centers for Disease Control says the possibility of an Ebola outbreak on U.S. soil is extremely small.
