Introduction Purpose Use this section to understand and follow national and Alaska guidelines to classify patients with tuberculosis (TB) disease and latent TB infection (LTBI); detect suspected cases of TB; know when to report suspected or confirmed cases of TB; and diagnose TB disease. It is important to understand when a person should be evaluated further for TB disease. Not recognizing TB symptoms promptly will lead to delays in treating a TB case—and to more infection, TB disease, and contacts to evaluate. In the 2005 guideline, “Controlling Tuberculosis in the United States: Recommendations from the American Thoracic Society, Centers for Disease Control and Prevention, and the Infectious Diseases Society of America,” one of the recommended strategies to achieve the goal of reduction of TB morbidity and mortality is early and accurate detection, diagnosis, and reporting of TB cases, leading to initiation and completion of treatment. 1 Contacts are mentioned within this section, but their evaluation and followup and contact investigation are covered in more depth in the Contact Investigation section 11.1. For information on treatment, refer to the Treatment of Tuberculosis Disease section 6.1. Improvement in the detection of TB cases is essential to progress toward elimination of TB in the United States. 2 Case detection includes the processes that lead to the presentation, evaluation, receipt of diagnosis, and reporting of persons with active TB. 3 Detecting and reporting suspected cases of TB are key steps in stopping transmission of Mycobacterium tuberculosis because it leads to prompt initiation of effective multipledrug treatment, which rapidly reduces infectiousness. 4 TB is commonly diagnosed when a person seeks medical attention for symptoms caused by the disease or a concomitant medical condition. Thus, healthcare providers, particularly those providing primary healthcare to populations at high risk, are key contributors to TB case detection. 5 The majority of pulmonary TB cases continue to be diagnosed at an advanced stage. Earlier diagnosis would result in less individual morbidity and death, greater success in treatment, less transmission to contacts, and fewer outbreaks of TB. 6 A L A S K A T U B E R C U L O S I S P R O G R A M M A N U A L Diagnosis of Tuber culosis Disease 5.2 R e v i s e d N o v e m b e r 2 0 1 2
