In an unprecedented and tragic case, a Michigan resident has succumbed to rabies after receiving a kidney transplant from a donor who harbored the virus, marking the first human rabies death in the state since 2009. This incident underscores the complexities and risks associated with organ transplants.

The deceased, whose identity remains undisclosed, underwent the kidney transplant at the University of Toledo Medical Center (UTMC) in Ohio in December 2024. Unfortunately, they passed away just a month later, in January 2025. According to the Michigan Department of Health and Human Services (MDHHS) spokesperson, this rare event has drawn attention to the potential for rabies transmission through organ transplantation—an occurrence that is extremely unusual.

Rabies is a viral infection that predominantly affects mammals, including humans, and is almost always fatal once clinical symptoms manifest. While rabies is typically transmitted through the bite of an infected animal, this case highlights the unusual risk presented by organ donors. The Centers for Disease Control and Prevention (CDC) reports that person-to-person transmission through organ transplants is documented in a handful of cases, primarily linked to rabid organ donors.

The CDC confirmed that the organ donor had been exposed to rabies from a wild animal in Idaho five weeks prior to their death. Alarmingly, the donor did not exhibit any classic symptoms of rabies and had not sought medical help or reported the incident to health officials, which could have initiated preventive measures.

Symptoms of rabies can initially mimic flu-like conditions, evolving into severe neurological issues, including hallucinations, paralysis, and hydrophobia (fear of water). Given the rapid progression of the disease, timely intervention is critical. Post-exposure prophylaxis (PEP), which includes wound cleansing and a series of rabies vaccinations, can prevent the onset of the disease following potential rabies exposure.

Remarkably, rabies-related deaths in the U.S. remain relatively low, with around 10 cases reported annually. Most U.S. rabies cases are linked to wildlife, particularly bats, raccoons, skunks, and foxes. Globally, domestic dogs are responsible for over 95% of rabies-related fatalities, emphasizing the significant public health focus on rabies prevention.

In the aftermath of the Michigan resident's death, notable action was taken concerning other transplant recipients who received corneal grafts from the same donor. A total of three patients in different states received these grafts and, following the emerging information about the transplant recipient's death, were administered PEP and are reportedly in good health. A fourth graft was intercepted before it could be implanted.

Experts, however, stress that while cases of rabies transmission through organ donations are concerning, they are exceedingly rare and should not deter patients from pursuing life-saving transplants. Dr. Daniel Kaul, a clinical professor at the University of Michigan, emphasized the catastrophic consequences of untreated organ failure vastly outweigh the risks presented by such rare occurrences.

Furthermore, organ screening processes strive to detect common infectious diseases, but the nature of rabies testing poses challenges due its quick post-transplant viability. Nevertheless, protocols ensure that donors showing signs of rabies or disclosing prior infection are excluded from the donation process.

This unfortunate incident adds to the database of documented rabies cases in organ transplantation, yet highlights the importance of continued vigilance, education, and preventive measures in the field of organ donation and transplantation.
