Surveillance data: active and passive data collection.
The National Tuberculosis Surveillance System collects information on each newly reported case of tuberculosis (TB) disease in the United States. The program is a cooperative effort of the Centers for Disease Control and Prevention (CDC) and state and local health departments, who report cases of TB to CDC.
Selected Content
The initial case report includes patient demographics, laboratory results, and risk factors associated with TB, in addition to other items. . Follow up reports collect drug susceptibility results, genotyping information, and treatment outcome, in addition to other items.
Population Covered
The U.S. population
All reporting areas (the 50 states, the District of Columbia, New York City, the 5 U.S. territories [American Samoa, Guam, Northern Mariana Islands, Puerto Rico, U.S. Virgin Islands], and the 3 freely associated states [Federated States of Micronesia, Republic of the Marshall Islands, Republic of Palau]) report TB cases to CDC electronically, using standard reporting criteria. Reported cases are verified according to the TB case definition for public health surveillance. Cases may be verified using the laboratory, the clinical case definition, or a provider diagnosis. Follow up reports collect information obtained after the initial case report has been submitted. Data are transmitted to CDC electronically, using CDC-supplied software.
