Atlanta ? A man with a rare and dangerous form of tuberculosis ignored doctors’ advice and took two trans-Atlantic flights, leading to the first U.S. government-ordered quarantine since 1963, health officials said Tuesday.

The man, whom officials did not identify, is at an Atlanta hospital in respiratory isolation.

The infected man flew from Atlanta to Paris on May 12 aboard Air France Flight 385. He returned to North America on May 24 aboard Czech Air Flight 0104 from Prague to Montreal. The man then drove into the United States at the Champlain, N.Y., border crossing.

He was potentially infectious at the time of the flights, so officials at the Centers for Disease Control and Prevention recommended medical exams for cabin crew members on those flights, as well as passengers sitting in the same rows or within two rows. CDC officials did not release row numbers but said the airlines were working with health officials to contact those passengers.
