Passenger contact investigation associated with a transport driver with pulmonary tuberculosis.

Objectives: In October 2008, pulmonary tuberculosis (TB) was diagnosed in a driver who had transported 762 passengers in the District of Columbia metropolitan area during his infectious period. A passenger contact investigation was conducted by the six public health jurisdictions because of concern that some passengers might be infected with HIV or have other medical conditions that put them at increased risk for developing TB disease if infected.

Methods: Authorities evaluated 92 of 100 passengers with at least 90 minutes of cumulative exposure.
