Latent TB Infection in USSOF: A Refresher and Update.

Tuberculosis (TB) causes approximately 2 million deaths annually worldwide, with 2 billion persons estimated to be actively infected with TB. While rates of active TB disease in the US military are low, military service in TB-endemic countries remains an uncommon, but important source of infection. United States Special Operations Forces (USSOF) and enablers often operate in TB-endemic countries and, as an inherent risk of their mission sets, are more likely to have high-risk exposure to TB disease. Military medical authorities have provided excellent diagnostic guidance; the Centers for Disease Control and Prevention (CDC) recently updated preferred regimens for the treatment of latent TB infection (LTBI). This review serves as a refresher and update to the management of LTBI in USSOF to optimize medical readiness through targeted testing and short treatment regimens.
