Tuberculosis transmission across three states: the story of a solid organ donor born in an endemic country, 2018.

Transmission of tuberculosis (TB) from a deceased solid organ donor to recipients can result in severe morbidity and mortality. In 2018, four solid organ transplant recipients residing in three states but sharing a common organ donor were diagnosed with TB disease. Two recipients were hospitalized and none died. The organ donor was born in a country with a high incidence of TB and experienced 8 weeks of headache and fever prior to death, but was not tested for TB during multiple hospitalizations or prior to organ procurement. TB isolates of two organ recipients and a close contact of the donor had identical TB genotypes and closely related whole-genome sequencing results. Donors with risk factors for TB, in particular birth or residence in countries with a higher TB incidence, should be carefully evaluated for TB.
