ATLANTA (AP) -- The head of the Centers for Disease Control and Prevention says authorities around the world are working to track down passengers who were seated near a man now quarantined with a rare form of tuberculosis.
Director Julie Gerberding says the man is probably not highly infectious, but says authorities have to err on the side of caution because the bacteria is "very deadly."
Health officials say the man had been advised not to fly and that he knew he could expose others when he boarded the jets from Atlanta to Paris, and later from Prague to Montreal.
The man, however, has told the Atlanta Journal-Constitution that doctors didn't order him not to fly -- and only suggested he put off his long-planned wedding in Greece.
He admits that he sneaked back into the U-S by way of Canada, after being told in Italy to turn himself in.
