Probable transmission of multidrug-resistant tuberculosis in a correctional facility--California

Abstract

During 1990-1991, an inmate in a California prison spent a total of 6 months in the prison infirmary with multidrug-resistant tuberculosis (MDR-TB). As a result, from November 1990 through March 1991, 11 of the 21 prison infirmary physicians and nurses underwent tuberculin skin testing; two persons could be documented as newly positive. In addition, two correctional officers (from an unknown number tested) also had newly positive tuberculin skin tests. State and local departments of health, industrial relations, and corrections investigated the possibility of nosocomial TB transmission from inmates to staff. This report presents the findings from their investigation.
