Tuberculosis in health care workers during declining tuberculosis incidence in New York State.

Background: Nosocomial tuberculosis (TB) transmission has decreased dramatically in New York State since 1992; however, health care workers (HCWs) still compose >3% of TB cases.

Methods: Aggregate surveillance data on incident TB cases from 1994 to 2002 were examined for trends among HCWs. Additional information was available for HCW cases from 1998 to 2002, including facility type, tuberculin skin test (TST) result at hire, and treatment of latent TB infection (TLTBI).
