Use of Video Directly Observed Therapy for Treatment of Latent Tuberculosis Infection - Johnson County, Kansas, 2015.

Tuberculosis (TB) is caused by the bacterium Mycobacterium tuberculosis and is spread from person to person through the air. TB can be spread in congregate settings, such as school environments, to varying degrees, based on factors including duration of contact and air ventilation (1); therefore, evaluating potential contacts and exposures can be challenging. In February 2015, a student at a Kansas high school received a diagnosis of active pulmonary TB disease.
