Somehow, tuberculosis was transmitted via a lung transplant in California, according to MedPage Today.

Genotyping revealed that the organ donor was linked after death to an ongoing TB outbreak that occurred in a separate county from where the organ recipient resided.

This finding has implications for health officials involved in TB control, the investigators wrote in the latest issue of the CDC’s Morbidity and Mortality Weekly Report, published online Aug. 3.

“Organ recipients and donors are often not located within a single health jurisdiction, and state TB control programs can play a critical role in systematically reviewing and interpreting TB genotypes from organ recipients,” wrote researcher Alexander Kay, MD, of the Tuberculosis Control Branch of the California Department of Public Health, and colleagues.
