RESUMO
A systematic approach to contact investigations has long been a cornerstone of interrupting the transmission of tuberculosis in community settings. This paper describes the implementation of a systematic 10-step contact investigation within an acute care setting during a multistate outbreak of healthcare-associated tuberculosis. A systematic approach to contact investigations might have applicability to the prevention of other communicable infections within healthcare settings.

A nationwide tuberculosis outbreak linked to a viable bone allograft product contaminated with Mycobacterium tuberculosis was identified in June 2021. Our subsequent investigation identified 73 healthcare personnel with new latent tuberculosis infection following exposure to the contaminated product, product recipients, surgical instruments, or medical waste.

On December 11, 2015, the Fort Wayne-Allen County (Indiana) Department of Health was notified by a local hospital laboratory of a suspected case of meningococcal meningitis based on Gram stain results of cerebrospinal fluid. The county health department interviewed close family members and friends of the patient to establish an infectious period, timeline of events, and possible exposures. Close medical and household contacts were offered chemoprophylaxis (1). This case was associated with an elementary school. The patient had intermittent, close, potentially face-to-face contact with many students, and was reported to have had a persistent, productive cough throughout the exposure period. In light of these unusual circumstances, and the fact that elementary school-aged children are not routinely vaccinated against meningococcal disease,* local and state health officials, with CDC support, decided to offer chemoprophylaxis to the patient's contacts. A total of 581 child and adult contacts were identified.
