Number of Contacts of Bacteriologically Confirmed Pulmonary TB Cases who Were Screened for TB Infection (and/or Tested for TBI) According to National Screening Protocols during the Specified Reporting Period

Number of contacts of bacteriologically confirmed pulmonary TB cases who were screened for TBI according to national screening protocols during the specified reporting period. Every contact will first be assessed for active TB as per national protocols; once active TB has been ruled out, assessment for TBI becomes relevant. This indicator is calculated as "total number of contacts screened" minus "the number of contacts who were diagnosed with TB." TBI screening protocols may vary by country; some countries may screen using a screening test such as TST or IGRA.
