Screening for Latent Tuberculosis Infection in Adults: US Preventive Services Task Force Recommendation Statement.
In the US, tuberculosis remains an important preventable disease, including active tuberculosis, which may be infectious, and latent tuberculosis infection (LTBI), which is asymptomatic and not infectious but can later progress to active disease. The precise prevalence rate of LTBI in the US is difficult to determine; however, estimated prevalence is about 5.0%, or up to 13 million persons. Incidence of tuberculosis varies by geography and living accommodations, suggesting an association with social determinants of health. ⋯ The USPSTF recommends screening for LTBI in populations at increased risk. (B recommendation).
