title: Guidelines for the investigation of contacts of persons with infectious tuberculosis. Recommendations from the National Tuberculosis Controllers Association and CDC.
abstract: In 1976, the American Thoracic Society (ATS) published brief guidelines for the investigation, diagnostic evaluation, and medical treatment of TB contacts. Although investigation of contacts and treatment of infected contacts is an important component of the U.S. strategy for TB elimination, second in priority to treatment of persons with TB disease, national guidelines have not been updated since 1976. This statement, the first issued jointly by the National Tuberculosis Controllers Association and CDC, was drafted by a working group consisting of members from both organizations on the basis of a review of relevant epidemiologic and other scientific studies and established practices in conducting contact investigations. This statement provides expanded guidelines concerning investigation of TB exposure and transmission and prevention of future cases of TB through contact investigations. In addition to the topics discussed previously, these expanded guidelines also discuss multiple related topics (e.g., data management, confidentiality and consent, and human resources). These guidelines are intended for use by public health officials but also are relevant to others who contribute to TB control efforts. Although the recommendations pertain to the United States, they might be adaptable for use in other countries that adhere to guidelines issued by the World Health Organization, the International Union against Tuberculosis and Lung Disease, and national TB control programs.
