1Total 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).
2Number of cases attributed to recent transmission includes any given case with a plausible source case regardless of cluster size.
3Number 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).
4Excludes New York City.
