"2023 U.S. Tuberculosis Surge Linked to Contaminated Bone Allografts"
A second nationwide tuberculosis (TB) outbreak in the United States in 2023 has been linked to contaminated bone allografts containing live cells from a deceased donor, similar to an outbreak in 2021. The Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) responded promptly, preventing the use of the implicated allografts in up to 53 additional patients. This incident highlights the need for improved donor screening, culture-based testing, and public health practices to prevent Mycobacterium tuberculosis transmission through tissue transplantation.
