Hood River County health officials have confirmed three cases of Creutzfeldt-Jakob disease (CJD), a rare and invariably fatal brain disorder, within the past eight months. Two of the affected individuals have died, while the third remains under investigation, according to a statement released by the Hood River County Health Department on April 14, 2025.
CJD is a rapidly progressive neurodegenerative disease caused by infectious proteins called prions, which induce abnormal folding of normal brain proteins, leading to brain damage. The disease is characterized by symptoms such as severe cognitive decline, memory loss, personality changes, loss of coordination, speech difficulties, visual disturbances, and involuntary jerking movements. As the disease advances, patients lose mobility and brain function, ultimately resulting in death within months to a year after symptom onset. There is currently no cure or treatment to halt or slow the progression of CJD; medical care focuses on symptom relief and supportive measures.
One of the three cases was confirmed through autopsy, while the other two are considered probable and await post-mortem confirmation, which involves detailed examination of brain tissue and cerebrospinal fluid and can take several months. The health department has emphasized that there is no identifiable link between these cases at this time, and investigations are ongoing in collaboration with the Oregon Health Authority and the Centers for Disease Control and Prevention (CDC). Officials are examining potential common risk factors but note that such findings are often inconclusive due to the complex nature of prion diseases.
Hood River County, with a population of about 23,000 to 24,000 people, has seen an unusual cluster of cases given that CJD typically affects 1 to 2 people per million worldwide, with around 350 cases reported annually in the United States. Despite the cluster, the risk to the general public remains extremely low. CJD is not contagious through air, water, touch, or social contact. Transmission can only occur through direct exposure to infected brain or nervous system tissue, typically in medical settings involving contaminated instruments or tissue transplants. The current cases are not believed to be linked to contaminated beef or environmental sources.
Health officials urge individuals with neurological symptoms such as rapid cognitive decline or unusual motor disturbances to seek medical evaluation. Healthcare providers in the region have been alerted to consider CJD in their differential diagnoses. The Hood River County Health Department pledges to continue monitoring the situation and keep the public informed of any new developments or risks to public health.
