Tuberculosis outbreak in a community hospital--District of Columbia, 2002.
After declining for nearly 30 years, during 1985-1992, tuberculosis (TB) rates in the United States experienced a resurgence, and several large nosocomial TB outbreaks occurred. Although data on such outbreaks are not collected systematically by CDC, the occurrence of nosocomial TB is believed to have declined sharply since the issuance and widespread implementation of infection-control guidelines in 1994. During April 2-September 12, 2002, TB was diagnosed in six persons who either had been patients or had worked in a large community hospital (hospital A) in March or early April. This report describes the results of an investigation of the presumed source patient, who had spent 3 weeks on two general medical wards of hospital A before being placed in respiratory isolation and having TB diagnosed on April 2. To prevent transmission of Mycobacterium tuberculosis, hospital staff should remain vigilant to identify and treat suspected TB cases promptly.
