World TB Day 2021

On March 24 each year, CDC joins the global community to observe World Tuberculosis (TB) Day – an important moment to unite in renewed commitment to ending TB.

Although preventable and treatable, TB remains one of the world’s deadliest infectious diseases, taking the lives of approximately 4,000 people every day. CDC is using technical expertise to drive innovation and advancement in TB prevention and treatment, and working on the frontlines with global partners to end TB as a public health threat. This World TB Day, CDC renews our commitment to finding, curing, and preventing all forms of TB at home and around the world.

Latest Research

New research highlights CDC’s leadership in the fight against drug-resistant TB, as well as the latest data on the economic outcomes of TB treatment and information on HIV and TB co-infection.

  • Impact of Effective Global Tuberculosis Control on Health and Economic Outcomes in the United States.
    A CDC study found that strengthening TB control efforts in high burden countries abroad can lead to health and economic benefits here in the United States. The modeling study, led by researchers from CDC and Harvard, Stanford, and Yale universities, found that investing in global TB control efforts can save thousands of lives in the United States and billions of dollars in healthcare and related costs.

  • Pre-Treatment loss-to-follow-up Among Children with Multidrug-Resistant Tuberculosis in South Africa, 2008–2010.
    Multidrug-resistant (MDR) TB is more difficult to diagnose and treat compared with drug-susceptible TB. Compared to adults, young children are at greater risk of severe TB disease and death when treatment is delayed. This research sought to describe characteristics of children (<13 years) diagnosed with MDR TB between 2008–2010 in three South African provinces and assess factors associated with loss-to-follow-up before treatment was initiated.

  • Tuberculosis Preventive Treatment Scale-Up Among Antiretroviral Therapy Patients in 16 Countries Supported by The U.S. President’s Emergency Plan for AIDS Relief, 2017–2019.
    Tuberculosis preventive treatment (TPT) decreases morbidity and mortality among persons living with HIV but remains underutilized. The U.S. President’s Emergency Plan for AIDS Relief (PEPFAR) has committed to providing TPT to all eligible persons receiving antiretroviral therapy (ART) under the program by 2021. During April 1, 2017–March 31, 2019, TPT implementation improved substantially across 16 countries accounting for approximately 90% of all PEPFAR-supported ART patients.
  • Effect of Tuberculosis Screening and Retention Interventions on Early Antiretroviral Therapy Mortality in Botswana: A Stepped-Wedge Cluster Randomized Trial.
    In a recent study published in BMC Medicine, researchers implemented a package of interventions to strengthen intensified TB case finding and to improve retention of people living with HIV on antiretroviral therapy (ART), and assessed its impact on reducing early ART mortality. The package of interventions aimed to strengthen World Health Organization-recommended TB symptom screening, intensify TB case finding algorithms, and use active tracing to improve retention of HIV and TB/HIV co-infected patients in treatment.
