Tuberculosis in Healthcare Workers: A Molecular Epidemiologic Study in San Francisco

Abstract

Although most cases of tuberculosis in HCWs, as in non-HCWs, developed as a result of endogenous reactivation of latent infection, at least half of clustered cases of tuberculosis in HCWs were related to work. The number of work-related cases of tuberculosis in HCWs decreased during the study period.
