1Counties (and county equivalents) that had >5% of cases attributed to extensive recent transmission are included in table 66.
2Total 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).
3Total number of unique GENTypes identified in the county among all genotyped cases that are eligible to be evaluated for recent transmission.
4Number of cases attributed to overall recent transmission includes any given case with a plausible source case regardless of cluster size.
5Number 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).
6Proportion of cases attributed to extensive recent transmission calculated for counties with 10 or more genotyped cases.
