TB Notes 1, 2021
Notes from the Director
Last week, we recognized World TB Day on March 24th to commemorate the date Dr. Robert Koch announced his discovery of the bacillus that causes tuberculosis (TB). World TB Day activities looked different this year, due to the impact of the COVID-19 pandemic, but it remained an opportunity to increase awareness about TB disease and the need to find, treat, and prevent this devastating disease.
Many of our TB colleagues across the country and around the world also continue to address public health needs in the response to the COVID-19 pandemic. I am inspired by the stories of CDC’s 2021 U.S. TB Elimination Champions, and want to thank them, as well as all of the public health and medical professionals who are on the frontlines responding to the COVID-19 pandemic while continuing to work towards TB elimination. As the response to COVID-19 continues, it is important for TB programs to continue to maintain essential services of TB prevention and control. I encourage you to visit CDC’s TB and Public Health Emergencies and COVID-19 websites for information and resources.
On March 25, 2021, CDC published provisional 2020 U.S. TB surveillance data. Provisional data show a dramatic decline in reported TB cases among U.S.–born and non-U.S.–born individuals in 2020. The decline is likely due to multiple factors related to the COVID-19 pandemic, and raises concerns about missed or delayed TB disease diagnoses. Healthcare providers should consider TB testing for patients with signs and symptoms consistent with TB disease (e.g. cough, fever, night sweats, and weight loss), and people should be encouraged to seek medical care if needed.
CDC released new videos as part of the ongoing TB Personal Stories series to raise awareness about TB in the United States. Hearing experiences from TB survivors can be a helpful motivational tool that TB programs and healthcare providers can use to encourage patients to complete treatment for TB disease. I would like to thank the TB survivors, We Are TBexternal icon, The National TB Controllers Associationexternal icon, state and local TB programs, and Stop TB USAexternal icon for their participation in this important project. You can view the video, print, and social media content for each story by visiting CDC’s TB Personal Stories website.
CDC and our domestic and global partners remain committed in our efforts to eliminate TB, even as the COVID-19 pandemic continues to create challenges for our communities, public health departments, and healthcare facilities. Thank you for your continued efforts towards our goal of TB elimination.

CDC.gov World TB Day Feature Article
CDC.gov published a Feature article co-authored by the Division of Tuberculosis Elimination and the Division of Global HIV and Tuberculosis to highlight progress in the United States and around the world to end TB. The article highlights the impact of COVID-19 on TB elimination and the need for better diagnostics, shorter treatment regimens, and strong domestic and global partnerships to accelerate progress toward the elimination of TB disease. CDC and our domestic and global partners remain committed in our efforts to end this devastating disease, even as the COVID-19 pandemic has created unprecedented challenges for our communities, public health departments, and healthcare facilities.
World TB Day News and Events Timeline
To highlight World TB Day activities happening across the country, CDC created a 2021 World TB Day News & Events Timeline. Many of our partners held their activities virtually due to the COVID-19 response. Thank you to everyone who shared a World TB Day activity – there were 11 different events featured on the website! Learn more about the events that occurred across the United States on the News and Events Timeline webpage.
World TB Day Digital Media Toolkit
This year, CDC created a World TB Day digital toolkit designed to help plan communication activities to inform and educate partners, stakeholders, and media about TB-related problems and solutions, and the importance of supporting TB control and prevention efforts. The digital media toolkit included sample messaging, resources, and virtual events.
Updated resource: The Core Curriculum on Tuberculosis: What the Clinician Should Know
On March 19, 2021, CDC released an updated edition of the Core Curriculum on Tuberculosis: What the Clinician Should Know pdf icon[PDF – 6.65 MB]. This 2021 edition is an update to the 2013 edition and contains updated information about the treatment of latent TB infection and TB disease, based on the latest available guidance. The Core Curriculum resource is intended for use as a reference manual for clinicians caring for persons with or at high risk for TB disease or latent TB infection. The curriculum is designed in a self-study format so that each person can work at his or her own pace to learn more about latent TB infection and TB disease. Continuing education (CE) credits for this course are offered free of charge. To learn more, visit the CDC website.
Provisional TB Surveillance Data for 2020 Show a Dramatic Decline in Reported TB Cases in the United States
On March 25, 2021, DTBE published provisional 2020 U.S. TB data in Morbidity and Mortality Weekly Report. Data reported to CDC’s national TB surveillance system show a dramatic decline among U.S.-born and non-U.S.–born individuals. This decline is likely due to multiple factors related to the COVID-19 pandemic, and raises concerns about missed or delayed TB disease diagnoses.
The number of TB disease cases in the United States has fallen steadily since 1993, thanks to the dedicated work of TB programs to detect, treat, and prevent TB disease. Since 2010, TB incidence has decreased by an average of 2%–3% annually. However, provisional data show a 20% reduction in the number of reported cases of TB disease in the United States in 2020 (7,163 cases) compared with 2019 (8,909 cases). The incidence rate of TB disease in the United States in 2020 was 2.2 per 100,000 persons compared with 2.7 per 100,000 persons in 2019.
The decline in reported TB cases is much larger than has been observed in recent years and is likely due multiple factors related to the COVID-19 pandemic that have led to both an under-ascertainment of cases and a true decline in TB disease incidence. While COVID-19 pandemic mitigation efforts and reduced travel might have contributed to the decline, the size of the decrease across different groups raises concerns about missed or delayed TB disease diagnoses. CDC is conducting supplemental analyses to further examine the causes of the steep decline in cases.
Timely TB diagnoses save lives and prevent the spread of TB disease. CDC encourages healthcare providers to consider TB disease when evaluating patients with signs and symptoms consistent with TB disease, especially when SARS-CoV-2 diagnostic tests are negative. People with signs and symptoms of TB disease (e.g. cough, fever, night sweats, and weight loss) should seek medical care.

Preliminary study results show clinicians favor short-course treatment regimens for latent TB infection
Healthcare providers in clinics affiliated with local TB programs are moving towards selecting shorter-term regimens for treatment of latent TB infection, according to preliminary results of a CDC-funded study. The finding is an encouraging indicator of progress in the effort to improve treatment completion for latent TB infection.
More than 80% of people who develop TB disease in the United States each year get sick from longstanding, untreated latent TB infection. CDC estimates that up to 13 million people in the United Statesexternal icon have latent TB infection. These people are infected with Mycobacterium tuberculosis but do not have TB disease, have neither signs nor symptoms of TB disease, and cannot spread M. tuberculosis to others. However, about 5%-10% of infected people will develop TB disease over their lifetime if not treated for latent TB infection. Healthcare providers can accelerate progress toward TB elimination by identifying and treating people with latent TB infection, thereby preventing TB disease.
In 2020, CDC and the National Tuberculosis Controllers Association (NTCA) published “Guidelines for the Treatment of Latent Tuberculosis Infection” in CDC’s Morbidity and Mortality Weekly Report Recommendations and Reports that preferentially recommend short-course, rifamycin-based, 3- or 4-month latent TB infection treatment regimens over 6- or 9-month isoniazid monotherapy. Studies have shown that the shorter treatment regimens have similar efficacy, better tolerability, and are more likely to be completed than 6 or 9 months of isoniazid. However, little information is available on how clinicians have responded to the changes in the recommendations and if they have moved toward prescription of shorter regimens. Information on clinicians’ responses to shorter treatment regimens is important to policymakers, program evaluators, and public health leaders as they work to improve testing and treatment of latent TB infection.
To assess how clinicians have responded to the changes in the recommendations, researchers analyzed data from the CDC-funded TB Epidemiologic Studies Consortium (TBESC), a partnership of 10 academic institutions and public health departments in 11 U.S. states. From September 2012 ̶ May 2017, TBESC led a study to describe and compare the ability of three diagnostic tests – TB skin test (TST) and two interferon gamma release assays (IGRAs) – to predict progression to TB disease. Extensive treatment information was collected for study participants who had at least one positive test result and were offered and accepted latent TB infection treatment. From the subgroup of 4,068 participants who had detailed treatment information available, study results revealed that clinicians’ preferences for the two short-course regimens in standard use at the time of the study increased from 53% in 2013 to 73% in late 2016. The two short-course regimens in standard use at the time of the study were three months of once-weekly isoniazid plus rifapentine (3HP) and four months of daily rifampin pdf icon[PDF – 406KB] (4R). The results of the study demonstrate that more clinicians are recommending short-course treatment options for latent TB infection. CDC continues to develop messages to inform healthcare providers, TB programs, and the public about treatment options for latent TB infection.

TB Tests and COVID-19 Vaccines
COVID-19 vaccination is an important tool to help stop the pandemic, and as the U.S. COVID-19 vaccination program continues, some may have questions about the interaction between COVID-19 vaccines and tests used for tuberculosis (TB) infection.
The COVID-19 vaccine should not be delayed because of testing for TB infection. TB skin tests and TB blood tests are not expected to affect the safety or the effectiveness of the COVID-19 vaccine. Visit Interim Clinical Considerations for Use of COVID-19 Vaccines Currently Authorized in the United States for more information.

Division of Tuberculosis Elimination staff have begun piloting a tool to assess the costs of electronically directly observed therapy (eDOT). In particular, the Excel-based tool evaluates the cost of video directly observed therapy (video DOT), estimates the resources needed to start a video DOT program, and allows for comparison to telemedicine reimbursement rates. Currently, two jurisdictions are in the initial stages of piloting the tool: Los Angeles and Kentucky.
With the video DOT costing tool, programs do not need to go through a large data collection and analysis process to evaluate their cost. Instead, the basic information required to use the tool are (1) the number of patients who use video DOT, (2) the expected cost of the video DOT software platform, and (3) whether or not the program will be providing smartphones for patients. The tool uses data previously collected during a three-site evaluation to estimate costs (Beeler Asay et. al., 2020). The three-site evaluation found that video DOT was preferred to traditional forms of DOT (Field and Clinic) from the health department and patient cost perspective. However, video DOT costs varied by site, and lower-incidence sites had greater costs per session. The video DOT costing tool will allows sites to compare their costs with the published evaluation.

NSTC/NTCA Release Testing and Treatment of Latent Tuberculosis Infection in the United States: Clinical Recommendations
The National Society of Tuberculosis Clinicians (NSTC), a section of the National Tuberculosis Controllers Association (NTCA), released Testing and Treatment of Latent Tuberculosis Infection in the United States: Clinical Recommendationsexternal icon. Led by NSTC members Drs. Marcos Burgos and Charlie Crane, a national group of TB experts developed these patient-centered and practical state-of-the-art recommendations as a companion reference to support health care providers in implementing the 2020 latent TB infection treatment recommendations, “Guidelines for the Treatment of Latent Tuberculosis Infection: Recommendations from the National Tuberculosis Controllers Association and CDC.”
The Clinical Recommendations are written for health care providers in both the public and private sectors and the authors include clinicians and nurses with experience in TB from multiple perspectives: professional roles in patient care, public health, and scientific research and locations with different epidemiology and public health infrastructure and resources. Their medical background, clinical experience, and research based the recommendations on the best available knowledge, whether research- or expert opinion-based.
The Clinical Recommendations will be a living document that resides on the NTCA websiteexternal icon and will be updated as the TB community learns more about LTBI testing and treatment. Learn more in the press releaseexternal icon published on February 5, 2021.

TB Community Engagement Network is now the TB Elimination Alliance
The TB Elimination Alliance (TEA), formerly known as the TB Community Engagement Network, is a CDC-funded initiative to work more closely with state and local TB control programs, as well as community-based organizations and community health centers. The initiative is spearheaded by the Association of Asian Pacific Community Health Organizations, Asian & Pacific Islander American Health Forum, Hepatitis B Foundation, and Stop TB USA. TEA’s mission is to cultivate a national partnership of community leaders dedicated to eliminating TB disease and latent TB infection inequities among Asian American, Native Hawaiian, and Pacific Islander populations through education, raising awareness, and innovation. TEA’s vision is to create healthy communities free of TB.
TEA was formally launched in July 2020, and members include 14 organizations spanning from Hawaii to Washington D.C. Members include community-based organizations, community health centers, local coalitions, health agencies, and academic institutions that serve patients with limited English proficiency, immigrants, refugees, those with limited or no health coverage, and those at-risk for other infectious diseases. Members deliver culturally and linguistically appropriate services to serve vulnerable and marginalized communities. Collectively, the members represent a workforce of more than 2,000 clinicians, non-clinical providers (e.g., Community Health Workers), public health administrators, and volunteers.
TEA’s goals are to conduct outreach to underserved Asian American, Native Hawaiian, and Pacific Islander communities with the highest TB burden, increase awareness and understanding of culturally and linguistically appropriate latent TB infection/TB disease testing and treatment strategies, share resources and best practices among providers, and develop partnerships to scale existing initiatives. To date, TEA has hosted several trainings, including an inaugural virtual TB Summit in November 2020, and implemented a Mini-Grants program for community-based organizations and community health centers to innovate in TB elimination.
