Summary
Comprehensive guidelines for treatment of latent tuberculosis infection (LTBI) among persons living in the United States were last published in 2000 (American Thoracic Society. CDC targeted tuberculin testing and treatment of latent tuberculosis infection. Am J Respir Crit Care Med 2000;161:S221–47).
Introduction
One fourth of the global population (approximately 2 billion persons) is estimated to be infected with Mycobacterium tuberculosis ( 1 ), including approximately 13 million in the United States ( 2 ). Most infected persons are asymptomatic and classified as having latent tuberculosis infection (LTBI).
Methods
These updated guidelines were developed by NTCA and CDC. The LTBI treatment guidelines committee members, who are the authors of this report, were nominated on the basis of their expertise in treatment of LTBI.
Discussion
A systematic literature review was performed of clinical trial data pertaining to effectiveness and toxicity of treatment of LTBI, including studies published since the 2018 World Health Organization LTBI guidelines ( 95 ).
Other Considerations
Following are several considerations for the use of these guidelines. First, the committee did not include cost-effectiveness in evaluating the evidence; recommendations were based on evaluating effectiveness and toxicity of the regimens.
Conclusion
For patients without drug intolerability or drug-drug interactions, short-course (3–4 months) rifamycin-based treatment regimens are preferred over the longer-course (6–9 months) isoniazid monotherapy for treatment of LTBI.

Latent tuberculosis infection (LTBI) is the presence of M. tuberculosis organisms (tubercle bacilli) without symptoms or radiographic or bacteriologic evidence of TB disease. Approximately 90-95% of those infected are able to mount an immune response that halts the progression from LTBI to TB disease. However, because prevention of TB has major public health implications, the Centers for Disease Control and Prevention (CDC) and the United States Preventive Services Task Force (USPSTF) recommend testing populations that are at increased risk for TB infection and treating those for whom TB disease has been ruled out. Health care providers must communicate the risks and benefits of treatment to their patients and encourage adherence and treatment completion.
