Investigation of a Genotype Cluster of Tubercuosis Cases --- Detroit, Michigan, 2004--2007
This report describes the investigation of a genotype cluster of eight tuberculosis cases in US born patients in the Detroit metropolitan area. The investigation was done by the Detroit Department of Health and Wellness Promotion, the Michigan Department of Community Health, and the Centers for Disease Control and Prevention.

Seven additional cases were reported in patients with TB genotypes matching that of the index patient.
