Background: Tuberculosis (TB) cases and deaths in the United States fluctuated substantially during the COVID-19 pandemic. We analyzed multiple data sources to understand the factors contributing to these changes and estimated future TB trends.

Methods: We identified four mechanisms potentially contributing to observed TB trends during 2020-2023: immigration, respiratory contact rates, rates of accurate diagnosis and treatment initiation, and mortality rates for persons with TB disease.

Importance: Despite significant progress made toward tuberculosis (TB) elimination, racial and ethnic disparities persist in TB incidence and case-fatality rates in the US.

Objective: To estimate the health outcomes and economic cost of TB disparities among US-born persons from 2023 to 2035.

Design, Setting, And Participants: Generalized additive regression models projecting trends in TB incidence and case-fatality rates from 2023 to 2035 were fit based on national TB surveillance data for 2010 to 2019 in the 50 US states and the District of Columbia among US-born persons.

Background: For settings with low tuberculosis incidence, disease elimination is a long-term goal. We investigated pathways to tuberculosis pre-elimination (incidence <1·0 cases per 100 000 people) and elimination (incidence <0·1 cases per 100 000 people) in the USA, where incidence was estimated at 2·9 per 100 000 people in 2023.

Methods: Using a mathematical modelling framework, we simulated how US tuberculosis incidence could be affected by changes in tuberculosis services in the countries of origin for future migrants to the USA, as well as changes in tuberculosis services inside the USA.

Background: In the United States, over 80% of tuberculosis (TB) disease cases are estimated to result from reactivation of latent TB infection (LTBI) acquired more than 2 years previously ("reactivation TB"). We estimated reactivation TB rates for the US population with LTBI, overall, by age, sex, race-ethnicity, and US-born status, and for selected comorbidities (diabetes, end-stage renal disease, and HIV).

Methods: We collated nationally representative data for 2011-2012.

Article Synopsis
  • - The study examines racial and ethnic disparities in tuberculosis (TB) diagnosis and treatment outcomes in the USA, using data from 2003 to 2019 to highlight differences along the TB continuum of care.
  • - Researchers analyzed national surveillance data to identify how various racial and ethnic groups, classified by US Census standards, experienced TB diagnosis (like diagnosis after death) and treatment results (such as treatment discontinuation and mortality during treatment).
  • - Findings revealed that non-Hispanic Black, Hispanic, and American Indian or Alaska Native individuals faced higher risks of adverse TB outcomes compared to non-Hispanic White individuals, indicating persistent disparities in TB management and care.

Background: In the United States, the tuberculosis (TB) disease burden and associated factors vary substantially across states. While public health agencies must choose how to deploy resources to combat TB and latent tuberculosis infection (LTBI), state-level modeling analyses to inform policy decisions have not been widely available.

Methods: We developed a mathematical model of TB epidemiology linked to a web-based user interface - Tabby2.

Little is known about co-occurring tuberculosis (TB) and COVID-19 in low TB incidence settings. We obtained a cross-section of 333 persons in the United States co-diagnosed with TB and COVID-19 within 180 days and compared them to 4,433 persons with TB only in 2020 and 18,898 persons with TB during 2017‒2019. Across both comparison groups, a higher proportion of persons with TB-COVID-19 were Hispanic, were long-term care facility residents, and had diabetes.

Objective: Tuberculosis (TB) is a public health problem, especially among people experiencing homelessness (PEH). The Advisory Council for the Elimination of Tuberculosis issued recommendations in 1992 for TB prevention and control among PEH. Our goal was to provide current guidelines and information in one place to inform medical and public health providers and TB programs on TB incidence, diagnosis, and treatment among PEH.

Objective: In 2020, the COVID-19 pandemic overburdened the US health care system because of extended and unprecedented patient surges and supply shortages in hospitals. We investigated the extent to which several US hospitals experienced emergency department (ED) and intensive care unit (ICU) overcrowding and ventilator shortages during the COVID-19 pandemic.

Methods: We analyzed Health Pulse data to assess the extent to which US hospitals reported alerts when experiencing ED overcrowding, ICU overcrowding, and ventilator shortages from March 7, 2020, through April 30, 2021.

Background: Reductions in tuberculosis (TB) transmission have been instrumental in lowering TB incidence in the United States. Sustaining and augmenting these reductions are key public health priorities.

Methods: We fit mechanistic transmission models to distributions of genotype clusters of TB cases reported to the Centers for Disease Control and Prevention during 2012-2016 in the United States and separately in California, Florida, New York, and Texas.

Background: An elevated risk of tuberculosis (TB) disease in persons who have received tumor necrosis factor alpha inhibitor medications (TNF-α inhibitors) has been reported for nearly two decades, but clinical diagnostic features and outcomes of TB in this population remain poorly described.

Methods: We analyzed national surveillance data for TB cases among persons aged 15 years and older reported in the United States during 2010-2017 and associated mortality data reported through 2019 to describe the clinical characteristics of those receiving TNF-α inhibitors.

Results: Of 70 129 TB cases analyzed, 504 (0.

Introduction: Preventing tuberculosis (TB) disease requires treatment of latent TB infection (LTBI) as well as prevention of person-to-person transmission. We estimated the LTBI prevalence for the entire United States and for each state by medical risk factors, age, and race/ethnicity, both in the total population and stratified by nativity.

Methods: We created a mathematical model using all incident TB disease cases during 2013-2017 reported to the National Tuberculosis Surveillance System that were classified using genotype-based methods or imputation as not attributed to recent TB transmission.
