Nosocomial Transmission from an Adolescent with Sputum Smear-Negative Pulmonary Tuberculosis.
We describe a case of sputum smear-negative pulmonary tuberculosis in an adolescent boy, where a delay in diagnosis and institution of appropriate infection control measures resulted in transmission of infection to at least 3 and possibly as many as 6 healthcare workers. Lapses in the use of standard precautions for infection control were also identified.
