United Airlines said Thursday it is notifying passengers who were on flights with a man later diagnosed with Ebola and telling them how to contact federal health officials.
United said it is also telling passengers that officials at the Centers for Disease Control and Prevention believe the man could not have spread the disease during the flights because he was not showing symptoms and was not yet contagious.
On Sept. 19, Thomas Eric Duncan flew from Liberia in the heart of western Africa's Ebola outbreak zone to Belgium on a Brussels Airlines flight, according to Belgian officials.
United said it believes that Duncan flew the next day on United Flight 951 from Brussels to Dulles International Airport near Washington and connected to Flight 822 from Dulles to Dallas-Fort Worth International Airport.
United officials declined to say how many passengers were on the flights. The Brussels-to-Dulles flight was on a Boeing 777 that has 266 seats, and the flight to Dallas used an Airbus A320 with 138 seats.
