Methodology Notes

Treatment for latent TB infection substantially reduces the risk that TB infection will progress to disease. Certain groups are at very high risk of developing TB disease if infected. Identifiable population groups at high risk for TB vary in time and geographic area, depending on unique and changing TB related demographics.

Revision History

Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.

Description of Changes Since the Healthy People 2020 Launch

In 2013, the original baseline estimate was revised from 64.3% (2007) to 68.1% (2007). The former estimate was submitted as preliminary data. The latter estimate reflects the final national estimate. The target was not revised. In 2013, the phrase "and initiated treatment" was added to the numerator and denominator for clarity because not everyone with LTBI actually starts treatment. In 2013, the following phrases were added to the objective statement for clarity: Increase the percentage of *contacts to sputum smear-positive *tuberculosis* cases who complete treatment after being diagnosed with latent tuberculosis infection *(LTBI) and initiated treatment for LTBI.*
