title: Rapid large-scale deployment of tuberculosis testing in a high school - Riverside County, California, 2013-2014.
abstract: Mycobacterium tuberculosis, the causative agent of tuberculosis (TB), can spread from person to person through the air, which can make contact investigations particularly complex in heavily populated settings such as schools. In November 2013, a student (the index patient) at a southern California high school with approximately 2,000 students and staff members was diagnosed with active pulmonary TB. Because of an unexpectedly high number of positive tuberculin skin test results in the initial contact investigation, testing was extended to the entire school population, which had to be completed before the end of the school term. A total of 1,806 persons were tested in 24 hours. The rapid testing of the entire population of a high school is unusual and led to widespread media attention and community concern, requiring close coordination among branches of the County of Riverside Department of Public Health, local governments, and the school district. The testing resulted in identification of two additional cases of TB; in addition, 72 persons underwent treatment for latent TB infection (LTBI). This incident demonstrates the importance of a coordinated emergency response in a large-scale deployment of rapid testing, including efficiently focused resources, organized testing operations, and effective media relations.
