The Nevada Tuberculosis Prevention and Control Program assists state, local, and community efforts to decrease transmission of active tuberculosis (TB) and reduce the health burden associated with TB disease. The Nevada TB Program promotes patient-centered treatment and case management for individuals diagnosed with TB disease, promotes testing and preventative treatment for individuals with inactive or latent TB infection (LTBI) and those at high-risk for TB disease, monitors trends of TB and LTBI, and disseminates resources for healthcare providers and the public.

General Information on Tuberculosis

Tuberculosis (TB) is an airborne transmissible disease caused by the bacterium Mycobacterium tuberculosis. The bacteria usually affect the lungs but can also attack other organs in the body, such as the kidneys, spine, and brain. The most common symptoms of TB are persistent cough with blood or sputum, fever, loss of appetite, weight loss and sweating at night. Not everyone infected with TB bacteria becomes sick.

Inactive or latent TB infection occurs when the TB bacteria infect the body but do not cause symptoms. Latent TB infection is not contagious, however, it can become active (contagious) later if not treated. Approximately 80% of active TB cases in the U.S. occur among people with untreated latent TB infection. More than 13 million people in the U.S. are estimated to have latent TB infection while less than 10 thousand cases of TB are identified annually. Think of it as an iceberg floating in the ocean, the tip above the surface represents the small number of persons with TB disease and the large hidden iceberg under the water represents the large number of persons with inactive TB infection.

Learn more about your risk for exposure and infection with the TB bacterium and what to do if you suspect TB disease symptoms at the Centers for Disease Control and Prevention’s (CDC) informative webpages on TB Disease and latent TB infection (LTBI).


Think. Test. Treat TB. Together we can end tuberculosis.

For the public:

  • TB is one of the world’s leading infectious disease killers.
  • TB can live in your body for years without causing symptoms; this is called inactive TB or latent TB infection
  • Without treatment, 1 in 10 people with inactive TB infection will get sick in the future. 
  • Inactive TB can become active anytime and make you sick.
  • Protect yourself and your family; ask you doctor about getting tested for TB if you have risk factors for TB infection. Risk Factors for inactive TB infection include: 
    • Spent time with someone who had active TB disease.
    • A condition that weakens the immune system, including diabetes and some medications.
    • Residence or travel to a country outside of the United States.

For Healthcare Providers:

As a healthcare provider, you play a critical role in reducing the spread of tuberculosis in the U.S. and your community. Protect your patients.

  • Short course LTBI treatments are effective, reduce a person’s lifetime risk of developing TB disease, and can be managed in the non-specialty practices.

TB Infection Control for Healthcare Facilities

TB Disease and Latent TB Infection are reportable conditions in Nevada.

  • TB Disease- confirmed or suspected cases must be reported within 24 hours; click here for the Nevada Confidential Morbidity Report Form.
  • Latent TB Infection diagnosis (positive TB test, no symptoms or signs, and chest radiograph not consistent with TB disease) must be reported within five days; click here for the Nevada Confidential Morbidity Report Form.
  • Nevada Administrative Codes requiring TB screening and surveillance in healthcare settings: NAC 441A.375 and NAC 441A.380.
