Health officials seek 44 passengers who flew with TB infected woman

Health officials are tracking down American Airlines passengers in 17 states -- including Illinois -- for testing after a California woman flew while sick with a dangerous strain of tuberculosis.

The U.S. Centers for Disease Control and Prevention say a 30-year old California woman boarded an American Airlines flight in New Delhi, India on December 13.

The flight stopped at Chicago's O'Hare International Airport before continuing on to San Francisco.

CDC officials are working on tracking down 44 people who sat within two rows of the woman on the flight.

The woman is not being named by authorities. She is being treated in isolation at a California hospital.

A health official says because the disease is still in its early stages, doctors don't know what her prognosis is.
