TB Prevention

Recent weeks have seen a handful of new Tuberculosis (TB) cases reported in states including Maine, North Carolina and California. While TB is rare in the U.S., even a single active case warrants attention. This article provides an overview of what TB is & how it spreads. TB is caused by a bacterium (Mycobacterium tuberculosis) that typically attacks the lungs, forming lesions called “tubercles,” and can destroy lung tissue — severe disease can lead to respiratory failure.

This article reviews key clinical and public health considerations surrounding recent tuberculosis (TB) cases reported in Maine, North Carolina, and California. Although TB remains relatively rare in the United States, it continues to cause more than 1 million deaths annually worldwide and poses ongoing risks, particularly for individuals with weakened immune systems or those who live or work in congregate settings.

Tuberculosis (TB), a contagious bacterial infection primarily affecting the lungs, remains a health risk in the U.S. Though cases declined for decades, recent increases — including ~10,347 cases in early data from 2024 — suggest testing and treatment of latent TB is needed more than ever.  Testing is crucial both for diagnosing latent TB (where bacteria are present but symptoms are absent) and active TB disease (which is contagious and manifests symptoms).

This webpage explains Assembly Bill 2132, which mandates tuberculosis (TB) risk assessment and testing for adult primary care patients in California.

This information sheet outlines the steps in the tuberculosis (TB) care cascade, from diagnosis to treatment completion. It highlights the importance of accurate testing, adherence to treatment, and use of directly observed therapy to ensure successful outcomes and prevent TB transmission.

This guideline provides updated, evidence-based recommendations for diagnosing, treating, and managing latent tuberculosis infection (LTBI). It offers practical guidance for healthcare providers and public health programs, including testing options, treatment regimens, and considerations for special populations.

This webpage outlines treatment approaches for both inactive and active tuberculosis (TB), including medication regimens, side effects, adherence tips, and steps to prevent the spread of TB. It emphasizes the importance of taking TB medications as prescribed to ensure successful recovery and protect others.

This webpage provides clinical guidance on the diagnosis and treatment of tuberculosis (TB) and latent TB infection (LTBI) in Wisconsin, outlining risk assessment, symptom evaluation, testing methods, and treatment protocols. It includes links to CDC resources and encourages use of state and national tools to support accurate diagnosis and effective care.

This webpage provides an overview of active tuberculosis (TB) disease and latent TB infection (LTBI), including how TB spreads, symptoms, prevention, and treatment. It highlights key resources, fact sheets, and guidance for both the public and health professionals in Wisconsin.

This report outlines the National Institute of Allergy and Infectious Diseases' (NIAID) updated strategic plan to combat tuberculosis. It focuses on four key priorities: enhancing fundamental knowledge of TB, advancing diagnostic research, accelerating vaccine development, and supporting strategies to treat and prevent TB.
