Rabies Transmission via Organ Donation in the United States Has Been Documented Only Four Times Since 1978, and Every Case Was Fatal.

The recent Michigan case, where a man died after receiving a rabies-infected kidney from a donor who had contracted the virus while saving a kitten from a skunk, is the fourth such incident in U.S. history. Each of these cases has underscored the extraordinary rarity but devastating consequences of rabies transmission through transplantation.

The first known occurrence was in 1978, when a corneal transplant led to rabies infection in the recipient. At that time, rabies was not considered in donor screening, and the case highlighted the potential for human-to-human transmission via tissue.

A second cluster of cases emerged in 2004, when four recipients of organs from a single donor in Texas all died of rabies. The donor had been misdiagnosed with another neurological condition, and the rabies infection was only discovered after the recipients developed symptoms.

This incident prompted widespread alarm and led to new recommendations for considering rabies in cases of unexplained encephalitis in donors.

A third case occurred in 2013, when a kidney recipient in Maryland died of rabies more than a year after transplantation. The donor had been infected with a raccoon variant of the virus, and the recipient’s delayed onset of symptoms demonstrated how rabies can remain latent for months before manifesting.

This case reinforced the difficulty of detecting rabies in organ donors and the importance of long-term vigilance in recipients.

The fourth and most recent case, documented between October 2024 and February 2025, involved the Michigan man who received a kidney from an Idaho donor. The donor had contracted rabies after rescuing a kitten from a skunk attack, sustaining a scratch that introduced the virus. His organs were transplanted before rabies was suspected, and the recipient developed symptoms within weeks, dying in early 2025.

The CDC confirmed the infection as the silver-haired bat variant of rabies, which circulates widely in North American wildlife.

Taken together, these four cases illustrate the unique challenges rabies poses to transplant medicine. Unlike other infections, rabies is almost universally fatal once symptoms appear, and its incubation period can vary widely.

Because routine rabies testing is not feasible for all donors, the emphasis has shifted toward careful donor history-taking, especially when unexplained neurological illness or wildlife exposure is involved.

Experts argue that while the risk is vanishingly small, the consequences are so severe that heightened awareness is essential.

This historical perspective shows that rabies transmission via organ donation is not only rare but also catastrophic, with every documented case ending in death.

The Michigan tragedy now joins this small but sobering list, reminding the medical community of the need for vigilance in donor screening and public awareness of rabies risks.
