title: Tuberculosis: a re-emerging problem for health care workers.
abstract: The current upward trend in the incidence of tuberculosis, particularly in the USA, and the problems of treating multiply drug resistant strains of Mycobacterium tuberculosis have caused a resurgence of interest in this infection. This review describes the microbiology, routes of transmission and epidemiology of Mycobacterium tuberculosis infections. The emergence and problems of treating multiply drug resistant strains are outlined. The significant potential for occupationally acquired infection among health care workers is discussed, together with a summary of the available infection control measures currently being examined. The true level of occupational risk to dental personnel remains uncertain.
