Abstract
To refine estimates of how many persons in the United States are candidates for treatment of latent tuberculosis, we removed from analysis persons who self-reported prior treatment on the National Health and Nutrition Examination Survey 2011–2012. We estimate that 12.6 million persons could benefit from treatment to prevent active tuberculosis.
Highlights
To refine estimates of how many persons in the United States are candidates for treatment of latent tuberculosis, we removed from analysis persons who self-reported prior treatment on the National Health and Nutrition Examination Survey 2011–2012
Having already been treated for active TB or for latent TB infection (LTBI) was self-reported by 12.2% participants, or 1.8 million of the 14.1 million persons in the civilian, noninstitutionalized US population with a positive IGRA blood test result for TB infection
An estimated 12.6 million persons living in the United States with evidence of TB infection by IGRA result reported no prior TB treatment
Summary
To refine estimates of how many persons in the United States are candidates for treatment of latent tuberculosis, we removed from analysis persons who self-reported prior treatment on the National Health and Nutrition Examination Survey 2011–2012. To better estimate the number of persons in the United States who are candidates for LTBI treatment [8], we refined the NHANES-based estimate of the national LTBI prevalence by excluding from analysis persons who reported having received prior treatment for active TB or LTBI.
