World TB Day 2022

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

A quarter of the world’s population – nearly 2 billion people – are infected with the TB bacteria and approximately 10 million people become ill each year with the disease. Although it is preventable and treatable, TB remains one of the world’s deadliest infectious diseases, taking the lives of 4,100 people each day. This World TB Day, CDC affirms our commitment to finding, curing, and preventing all forms of TB at home and around the world.

World TB Day is a day to educate people about the impact of TB around the world, share successes in TB prevention, and raise awareness of the challenges that hinder our progress toward the elimination of this devastating disease. This is the third World TB Day we have observed amid the COVID-19 pandemic, and we continue to see the toll it takes on our domestic and global TB programs.

Transforming TB Care in Children Around the World

It's time to end TB: Changing the Course of the Global TB EpidemicGlobally, CDC supports TB prevention and treatment programs for children and adolescentspdf icon, who are more likely than adults to develop life-threatening forms of TB disease. Together with partners, CDC has made substantial progress in providing lifesaving TB preventative treatment to nearly 500,000 children living with HIV. To address difficulties in diagnosing TB among children, CDC and partners in high-burden countries are expanding the use of child-friendly novel approaches to help rapidly diagnose and treat TB, such as stool and urine samples and nasal aspirates.

To sustain pediatric TB response efforts, CDC TB experts have contributed to the World Health Organization’sexternal icon updated pediatric TB guidelines on the management of tuberculosis in children and adolescents. These updates include information on PEPFAR’s efforts to incorporate TB services into HIV programs. The guidelines highlight nearly a decade of progress in developing new tools and approaches for diagnosing and treating TB among children and includes promising approaches for decentralizing care and improving case detection and treatment outcomes.

Latest Research

Recent publications from CDC and partners describe progress made to prioritize child and adolescent TB; scale-up of TB preventive treatment (TPT); integrate TB and HIV services; and measure the positive impact of overseas TB screening on U.S. TB elimination efforts.

  • Evidence to Action: Translating innovations in management of child and adolescent TB into routine practice in high-burden countries
    Substantial progress has been made in prevention, detection, and treatment of pediatric TB; however, gaps remain. This manuscript highlights the role of partnerships in addressing remaining gaps by adapting policy, driving innovation, and scaling-up evidence-based interventions to improve TB services for children and adolescents.

  • Implementing TB preventive treatment within differentiated HIV service delivery models in global programs
    TB is the leading cause of death among people living with HIV (PLHIV) and TPT is an essential component of treatment for PLHIV. This article describes efforts to scale-up TPT through patient-centered services, which adapt various aspects of the HIV treatment continuum towards the unique needs of diverse communities.

  • Overseas treatment of latent tuberculosis infection in US–bound immigrants
    TPT decreases morbidity and mortality among PLHIV, 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.
  • Tuberculosis treatment within differentiated service delivery models in global HIV/TB programming
    Recent adaptations to HIV and TB services, precipitated by the COVID-19 pandemic, have improved patient satisfaction and retention in care. This commentary highlights these adaptations and outlines considerations and best practices for implementation for TB treatment among people living with HIV.
