Tuberculosis - United States, 2023.

After 27 years of declining U.S. tuberculosis (TB) case counts, the number of TB cases declined considerably in 2020, coinciding with the COVID-19 pandemic.

Tuberculosis - United States, 2022.

Incidence of reported tuberculosis (TB) decreased gradually in the United States during 1993-2019, reaching 2.7 cases per 100,000 persons in 2019. Incidence substantially declined in 2020 to 2.

Tuberculosis - United States, 2021.

During 1993-2019, the incidence of tuberculosis (TB) in the United States decreased steadily; however, during the later years of that period the annual rate of decline slowed (1) until 2020 when a substantial decline (19.9%) was observed. This sharp decrease in TB incidence might have been related to multiple factors coinciding with the COVID-19 pandemic, including delayed or missed TB diagnoses or a true reduction in TB incidence related to pandemic mitigation efforts and changes in immigration and travel (2).

Tuberculosis - United States, 2020.

Tuberculosis (TB) disease incidence has decreased steadily since 1993 (1), a result of decades of work by local TB programs to detect, treat, and prevent TB disease and transmission. During 2020, a total of 7,163 TB cases were provisionally reported to CDC's National Tuberculosis Surveillance System (NTSS) by the 50 U.S.

Tuberculosis - United States, 2019.

Since 1989, the United States has pursued a goal of eliminating tuberculosis (TB) through a strategy of rapidly identifying and treating cases and evaluating exposed contacts to limit secondary cases resulting from recent TB transmission (1). This strategy has been highly effective in reducing U.S.

Noncountable Tuberculosis Case Reporting, National Tuberculosis Surveillance System, United States, 2010-2014.

Objectives: Supplemental federal funding is allocated to state and local tuberculosis (TB) programs using a formula that considers only countable cases reported to the National Tuberculosis Surveillance System (NTSS). Health departments submit reports of cases, which are countable unless another (US or international) jurisdiction has already counted the case or the case represents a recurrence of TB diagnosed ≤12 months after completion of treatment for a previous TB episode. Noncountable cases are a resource burden, so in 2009, NTSS began accepting noncountable case reports as an indicator of program burden.

Tuberculosis - United States, 2017.

In 2017, a total of 9,093 new cases of tuberculosis (TB) were provisionally* reported in the United States, representing an incidence rate of 2.8 cases per 100,000 population. The case count decreased by 1.

Disparities in Tuberculosis Treatment Completion by Incarceration Status, U.S., 1999-2011.

Introduction: Treatment completion is the cornerstone of tuberculosis (TB) control strategy globally. Although the majority of reported TB cases in the U.S.

The US National Tuberculosis Surveillance System: A Descriptive Assessment of the Completeness and Consistency of Data Reported from 2008 to 2012.

Background: In 2009, the Tuberculosis (TB) Information Management System transitioned into the National TB Surveillance System to allow use of 4 different types of electronic reporting schemes: state-built, commercial, and 2 schemes developed by the Centers for Disease Control and Prevention. Simultaneously, the reporting form was revised to include additional data fields.

Objective: Describe data completeness for the years 2008-2012 and determine the impact of surveillance changes.

Tuberculosis among healthcare workers, United States, 1995-2007.

Objective: We examined surveillance data to describe the epidemiology of tuberculosis (TB) among healthcare workers (HCWs) in the United States during the period 1995-2007.

Design: Cross-sectional descriptive analysis of existing surveillance data.

Setting And Participants: TB cases reported to the Centers for Disease Control and Prevention from the 50 states and the District of Columbia from 1995 through 2007.

Tuberculosis in older adults in the United States, 1993-2008.

Objectives: To describe older adults with tuberculosis (TB) and compare demographic, diagnostic, and disease characteristics and treatment outcomes between older and younger adults with TB.

Design: Descriptive analysis of all confirmed people with TB aged 21 and older.

Setting: The National Tuberculosis Surveillance System (NTSS) for the 50 United States and the District of Columbia from 1993 to 2008.

Epidemiology of extrapulmonary tuberculosis in the United States, 1993-2006.

Background: Almost one-fifth of United States tuberculosis cases are extrapulmonary; unexplained slower annual case count decreases have occurred in extrapulmonary tuberculosis (EPTB), compared with annual case count decreases in pulmonary tuberculosis (PTB) cases. We describe the epidemiology of EPTB by means of US national tuberculosis surveillance data.

Methods: US tuberculosis cases reported from 1993 to 2006 were classified as either EPTB or PTB.

Trends in tuberculosis reported from the Appalachian region: United States, 1993-2005.

Context: Appalachia has been characterized by its poverty, a factor associated with tuberculosis, yet little is known about the disease in this region.

Purpose: To determine whether Appalachian tuberculosis risk factors, trends, and rates differ from the rest of the United States.

Methods: Analysis of tuberculosis cases reported to the Centers for Disease Control and Prevention's National Tuberculosis Surveillance System (NTSS) within the 50 states and the District of Columbia from 1993 through 2005.

Tuberculosis in South Asians living in the United States, 1993-2004.

Background: Patients with tuberculosis (TB) in the United States are often described in 2 broad categories, US-born and foreign-born, which may mask differences among different immigrant groups. We determined characteristics of patients born in South Asia and diagnosed as having TB in the United States.

Methods: All 224,101 TB cases reported to the US National Tuberculosis Surveillance System from the 50 states and the District of Columbia from 1993 to 2004 were included.
