Travelers expressed concern at Westchester County Airport in Harrison Thursday after hearing about an Atlanta man who knowingly traveled with a rare form of tuberculosis.

Andrew Speaker, 31, was diagnosed with a rare strain of tuberculosis, known as XTR, which does not respond to common treatments. Despite being advised by health authorities not to travel by plane, Speaker flew to Europe for his wedding and honeymoon.

Upon returning from his trip, he turned himself in at Bellevue Hospital in New York City and is now quarantined in Denver, Colorado.

Authorities are attempting to contact passengers who may have been seated close to Speaker on his flights.

Speaker's health concern has sparked interest from politicians. Sen. Charles Schumer (D-NY) has called for enhancing border controls to prevent a similar situation from occurring.
