Airline stocks are tumbling after news that the second health worker to be diagnosed with Ebola flew on a commercial flight the night before reporting a fever.
Shares of the major U.S. airlines were down between 4 percent and 6 percent in midday trading Wednesday.
Frontier Airlines announced that public-health officials were notifying passengers on Monday night's Flight 1143 from Cleveland to Dallas-Fort Worth. The airline's crew reports that the woman showed no symptoms during the flight.
Frontier says because of the short time between the flight and her fever, health officials were contacting all 132 passengers from the flight. Public-health professionals will interview the passengers and monitor those deemed to be at risk for contracting the virus, Frontier says.
