revealed no significant relationship between knowledge and the risk of tuberculosis transmission (p=0.662), while there was a significant relationship between preventive behavior and the risk of tuberculosis transmission (p=0.001). It can be concluded that preventive behavior is associated with the risk of tuberculosis transmission, whereas knowledge is not associated with the risk of tuberculosis transmission.
