Background

Mycobacterium tuberculosis

The Centers for Disease Control and Prevention (CDC) provides funding for tuberculosis control activities in 50 U.S. states and 9 cities (Baltimore, MD; Chicago, IL; District of Columbia; Houston, TX; Los Angeles, CA; New York City, NY; Philadelphia, PA; San Diego, CA; and San Francisco, CA) through the Tuberculosis Elimination and Laboratory Cooperative Agreement.  Information about each newly reported case of tuberculosis (TB) in the 50 states and 9 cities is submitted to CDC’s National TB Surveillance System (NTSS) with a standard form, the Report of Verified Case of TB (RVCT). The initial case report includes a patient’s demographic data, occupation, initial drug regimen, and information on HIV status, substance use, homelessness, and residence in correctional or long-term care facilities. Follow-up reports collect drug susceptibility test results for Mycobacterium tuberculosis isolates and treatment status, among other items.

CDC also collects information from states and cities about their contact investigation activities: finding and examining persons who have had contact with TB cases, and treating those found to have TB disease or latent TB infection (LTBI). Data for contact investigation are reported by each TB control jurisdiction annually through the Aggregate Reports for Program Evaluation (ARPE).

TB control programs

National TB Indicators are key process and outcome measures for TB control programs in the United States. These indicators are selected by CDC in cooperation with partners in state and local health departments. Data for calculating these indicators are derived from existing surveillance systems such as NTSS and ARPE. CDC publishes TB indicator data to assist in evaluating progress toward achievement of national objectives through monitoring of TB program performance, assessment of needs for education and technical assistance, and identification of areas that need improvement.[1] [2]  For the purposes of this report, states and cities were categorized into 3 groups based on the numbers of TB cases reported to NTSS in the relevant year for each indicator (2017 for TB incidence and known HIV status, 2016 for LTBI positive contacts of smear positive cases who started and completed preventive treatment, and 2015 for completion of treatment of newly diagnosed TB cases).  The cutoffs for the groups were determined by the numbers of cases that fell within the 33rd and 66th percentiles.  City results for Baltimore, MD; Chicago, IL; District of Columbia; Houston, TX; Los Angeles, CA; New York City, NY; Philadelphia, PA; San Diego, CA; and San Francisco, CA are not included in the respective state results (e.g., percentage of known HIV results for Texas are exclusive of known HIV results for Houston).
