Nine people in Illinois are being sought by public health departments after sitting near a woman who had tuberculosis on a flight from India to Chicago in early December, health officials said.
The woman, who has not been identified, was on American Airlines Flight 293 from New Delhi to Chicago's O'Hare International Airport on Dec. 13. She continued on another flight to San Francisco, where six days later she was diagnosed with the multiple drug-resistant strain of tuberculosis, said Shelley Diaz, a spokeswoman for the Centers for Disease Control and Prevention.
Over 90% of the people in India have been exposed to tuberculosis at one time or another. This does not hold true globally, of course.
