The epidemiology of tuberculosis in urban populations is changing.
Combining conventional epidemiologic techniques with DNA fingerprinting of Mycobacterium tuberculosis can improve the understanding of how tuberculosis is transmitted.
We used restriction-fragment-length polymorphism (RFLP) analysis to study M. tuberculosis isolates from all patients reported to the tuberculosis registry in San Francisco during 1991 and 1992.
These results were interpreted along with clinical, demographic, and epidemiologic data.
Patients infected with the same strains were identified according to their RFLP patterns, and patients with identical patterns were grouped in clusters.
Risk factors for being in a cluster were analyzed.
