Rabies Kills Kidney Transplant Patient After Donor Scratched by Skunk

A Hero's Act Turns Deadly

An Idaho man's attempt to save a kitten from a predatory skunk would ultimately claim two lives in an extraordinary chain of transmission that highlights critical gaps in organ donation safety protocols. In late October 2024, a skunk approached the donor as he held a kitten in an outbuilding on his rural property. During an encounter that rendered the skunk unconscious, the donor sustained a shin scratch that bled, but he did not think he had been bitten.

Five weeks later, the Idaho man began experiencing confusion, hallucinations, and difficulty swallowing. He was discovered unresponsive at home after a suspected heart attack, was reportedly revived at a hospital but was declared brain-dead and removed from life support. Hospital staff initially attributed his symptoms to chronic conditions, unaware of the skunk encounter that would prove fatal.

Hospital staff members who treated the donor were initially unaware of the skunk scratch and attributed his preadmission signs and symptoms to chronic comorbidities. The family documented the skunk encounter in the donor risk assessment, but the form did not screen for rabies, citing its "rarity in humans."

From Idaho to Michigan: A Fatal Transfer

In December 2024, an adult male Michigan resident received a left kidney transplant from an Idaho donor at an Ohio hospital. For five weeks, everything seemed normal. Then the symptoms began: tremors, weakness, confusion, and incontinence. Seven days after symptom onset, he was hospitalized with fever, hydrophobia, dysphagia, and autonomic instability.

The telltale sign emerged quickly—hydrophobia, an irrational fear of water that serves as rabies' calling card in humans. On hospital day 2, he required invasive mechanical ventilation. On hospital day 7, the recipient died. Testing confirmed what doctors suspected: Rabies virus RNA was detected in saliva, nuchal skin, and brain tissue samples. Viral characterization was consistent with the silver-haired bat rabies virus variant.

The investigation revealed a three-step transmission chain: a rabid bat infected the skunk, which infected the Idaho donor, who unknowingly passed the virus through his donated kidney. Health officials said the kidney recipient's death marks the fourth documented case of rabies transmission through an organ transplant in the U.S. since 1978.

Racing Against Time

Once rabies symptoms appear, survival becomes nearly impossible. The disease is almost always fatal once symptoms appear; fewer than 50 cases of survival have been documented worldwide, with medical specialists rarely succeeding in keeping patients alive despite extreme measures. This reality made the post-discovery response critical for other potential victims.

Health officials also reached out to 370 people who could have been in contact with the donor. Forty-six of them were recommended to undergo rabies procedures. Three people who received corneal tissue from the same donor had their grafts immediately removed and received post-exposure prophylaxis—a highly effective treatment when administered before symptoms develop.

Closing the Safety Gap

Rabies is excluded from routine donor pathogen testing because of its rarity in humans in the United States and the complexity of diagnostic testing. This case exposes a vulnerability in current protocols where animal exposure histories may not trigger appropriate screening measures.

Transplant teams are now advised to consult public health officials if a potential donor has recent bites or scratches from rabies-susceptible animals, especially if the donor has had unexplained neurological symptoms. However, "no standard guidance currently exists for addressing reported donor animal exposures by transplant teams."

The tragedy underscores how a single moment of compassion—a man protecting a kitten—can ripple through the medical system in unforeseen ways. While organ transplant-transmitted rabies remains extraordinarily rare, this case will likely reshape how donation teams evaluate potential risks, ensuring future heroes don't inadvertently become victims of their own kindness.
