(3.8)1 Total number of *M. tuberculosis* genotyped cases that are eligible to be evaluated for recent transmission (i.e., complete data for the plausible-source case method’s algorithm).2 Number of cases attributed to recent transmission includes any given case with a plausible source case regardless of cluster size.3 Number of cases attributed to extensive recent transmission includes only cases in a plausible chain of transmission of six or more cases (five secondary and one source case).4 Cavitary disease only assessed for persons with pulmonary TB and an abnormal x-ray.
